The AMF works to fight malaria in an extremely cost effective way with insecticide treated bed-nets. Every year hundreds of millions of people will be infected with malaria, and half a million of them will die, with many more being debilitated or disabled. Independent charity evaluators, such as GiveWell, have ranked the AMF as one of the most cost-effective charities in the world for over a decade, due to our long and well-studied track record preventing hundreds of millions of cases of malaria.

Our tech team is just a couple people, and all-remote. Our software is essential to the charity work we do; it is one of the ways we stand out among other charities, by allowing us to automate, analyze, and validate our work in novel ways. Our tech stack includes C# .NET, Blazor, and Python.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools.

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

- ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

- Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

- Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

- ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from leaders at Hugging Face, DeepMind, and Black Forest Labs, XTX Ventures & Balderton.

Identity Labs has generated 2B+ views across Twitter. We've worked with Bryan Johnson, Chamath Palihapitiya, Tony Fadell, partners at a16z, partners at Kleiner Perkins, and YC founders. We are a small team of 15 people.

If the 21st century gets defined by 100 influential ideas, Identity Labs wants to be instrumental in popularizing 10 of them.

We believe every founder who's built something massive has five Paul Graham level essays inside them. Our job is to find those essays and give them distribution.

We're hiring a Creative Director.

Your job is to sit with someone who built a billion dollar company, talk for two hours, figure out which idea from that conversation will make 10 million people stop scrolling on Twitter, then write it.

It's intellectual sparring plus longform journalism plus an obsessive understanding of what spreads on Twitter and why.

We're growing at 1500%+ YoY. A Creative Director can 5x their salary within 2 years as they grow into a Partner role.

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and tiny bit of Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Ridgeline International builds software that fights Ubiquitous Technical Surveillance (UTS), which is the growing threat of everyday commercial devices, apps, and networks being used to passively collect data on people and organizations without their knowledge. Think smartphones, smart TVs, IoT devices, and third-party apps leaking sensitive behavioral and location data at scale. Our tools help U.S. government and enterprise customers understand and manage that exposure, often before they even realize they have a problem.

This is a genuinely full-stack role. You will own features from design through deployment, working with Java (backend), Angular (frontend), REST and GraphQL APIs, SQL databases, and cloud infrastructure with DevOps workflows. For the first four months you will support legacy systems built on C# and Azure, then transition to our modern core platform. That bridge phase is intentional, not a bait-and-switch.

What you need:

U.S. citizenship required, ability to obtain a security clearance 5 or more years of professional software development Strong OOP fundamentals and relational database experience Comfort with REST APIs and a genuine growth mindset

Bonus if you have: Java or Angular experience, GIS or mapping work, DevOps and CI/CD, or containerization (Docker, Kubernetes).

Perks include flexible PTO, a generous 401k match up to 10% with automatic 3% safe harbor, full health benefits, HSA employer contribution, professional coaching, and personal privacy protection services.

At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action.

We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year.

Apply via the link above!

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures.

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—the foundational infrastructure where all biological data is transformed into life-saving breakthroughs. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + deep biological nuances) requires high-bandwidth, in-person collaboration.

We dissolved traditional departmental silos. We are hiring hardcore builders, not analysts, for a critical core role:

*Senior TypeScript (SDK & Platform):* You will architect our frictionless, AI-native SDK to scale our ecosystem. This is not a CRUD web dashboard. You will build a heavy local desktop application that bridges directly with a high-performance Rust data layer. You must treat the browser engine as a runtime for heavy local apps. The standard is simple: if the SDK is too messy for us to build blocks at AI-speed, it is too messy for the world.

The Offer: * Comp: Top-tier EU salaries (€90k - €120k EUR). * Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions - up to 50% in total). * The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin. * Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have." * Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search). * Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.

Process: No HR screening. You will talk directly to the engineering team.

Email me (I am the CEO): stanp [at] milaboratories [dot] com. Please mention "HN" in the subject and include your GitHub.

L2 Labs is a brand new applied AI lab advancing database systems, data mapping, and data integration. We're fast growing: we closed a pre-seed funding round, established partnerships with Cornell and NYU, and secured a large enterprise customer in less than 3 months. We are a team of hard-working researchers and engineers who are obsessive about intricate, greenfield data problems - we love whiteboarding, spinning up experiments, ordering pizza, and suddenly it’s 2am and we've actually solved something. We build impactful products + publish in A* research venues.

We are currently seeking Founding Research Scientists + SWEs, with very meaningful upside in the form of a generous equity package. To learn more/reach out, email hiring@l2labs.ai.

For those who know what they're doing - even without AI. Our focus is agentic engineering: building and improving systems, workflows, and engineering practices around AI agents and AI-assisted development. We use AI tools heavily, but we expect engineers to know when they help, when they hurt, and how to keep generated code out of the debt spiral.

This is a hands-on role for someone who cares about maintainability, testing, refactoring, deployment safety, and engineering judgment under pressure. You should be able to improve systems yourself, help other engineers work effectively with AI, and raise the bar across teams.

You’ll likely fit if DORA metrics are useful to you, not decorative; if you know why small commits matter; if you’ve seen what a good deployment pipeline does to a team; and if you can use AI to scale quality, not just output.

Apply at jobs@techtalk.at. No cover letter. Instead, tell us about a system you improved with AI, and what your contribution actually was. Find out more: https://techtalk.at/job-offers/principal-software-engineer-a...

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures. Lots of learning resources including a full AI engineering bootcamp when you onboard.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll be the first to know about it.

We’re hiring staff+ SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write open-source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

Machine Learning Infra Engineer: Own our GPU-backed serving stack, Kubernetes clusters, and media serving layer.

Systems Engineer (Real-Time Engine): Build our core server-side runtime. High-concurrency, low-latency systems. Python/Asyncio today, transitioning to Rust.

Why join?

Massive ownership in a high-bar, research-heavy environment.

Work on the frontier of multimodal generative AI and real-time graphics.

Competitive equity and the chance to shape a company from the ground up.

Apply: Check out the roles at https://www.nuancelabs.ai/careers and mention "hackernews" for how you heard about us.

Fully remote, fully async, fully open-source. A CRE is a point of contact available, both internally and externally, to advise on best practice. Normally, they are knowledgeable in a specific area (i.e. Realtime, Postgres) but they aim to be generalists on the platform as a whole. They do not have specific customers that they help; instead they get involved with deeper, longer-running cases to achieve an outcome.

Looking for more of a focused development role? Sure thing, we have many roles open!

We're building a computational geometry engine from scratch in C++20. B-Rep modeling, surface-surface intersection, tolerance-aware geometric algorithms, and next-gen data exchange formats like QIF and STEP AP242. Clean codebase, no legacy code, no C++98.

If you've worked on a geometry kernel, CAD internals, or computational geometry libraries, you know how rare it is to find a modern codebase in this space. We're looking for someone who has actually implemented or worked closely with things like half-edge data structures, NURBS/spline evaluation, parametric surface operations, or spatial indexing for geometric queries. Experience with ACIS, Parasolid, or OpenCascade is a strong signal.

Huge bonus if you understand GD&T, tolerancing, or model-based definition well enough to implement it, not just read a drawing. The intersection of manufacturing domain knowledge and C++ engineering skill is exactly what we're building for.

Small team, early stage. Every engineer has real influence over architecture and technical direction. This is also a customer-facing role: you'll participate in demos and technical conversations with enterprise customers, so communication skills matter.

Requirements: modern C++ (C++17/20), US citizenship (required for government CUI work).

$95K–$125K base + performance bonuses, health insurance, 401k match, home office budget, professional development budget. Fully remote, US time zones.

Looking for a player-coach: hands-on in TypeScript/Node.js + React + AWS (Lambda, ECS, RDS, SST, PostgreSQL) every day, while mentoring a junior engineer and owning architecture decisions. Healthcare integrations are messy (EHR systems, labs, SFTP file drops, claims data) - if you've done this kind of work, you know.

Healthcare/HIPAA experience strongly preferred. This is a path to running the technical operation, not a staff augmentation gig. Small team, real ownership, no bureaucracy.

Paid take-home assessment (no LeetCode). We compensate you for your time regardless of outcome.

Health/dental/vision (50% covered), 401(k), unlimited PTO.

I’m the CTO at GameBrain. I previously spent 6 years helping to build autonomous vehicle perception stacks at Cruise and Ford.

At Gamebrain, we’re applying SOTA computer vision models to help teams dramatically accelerate game prep and scouting, saving days of manual repetitive work per week to give coaches and analysts massive leverage over their opponents. One of the biggest unlocks: legal access to real, high-quality sports data through deep relationships in the sports industry. Anyone who has built production CV systems knows how rare, and how valuable, that is.

I'm hiring a Staff Deep Learning Computer Vision Engineer. If you've spent your career designing, training, and scaling complex perception stacks - in AV, robotics, AR/VR, or anywhere that demands rigorous 3D spatial reasoning and multi-view fusion - this role was made for you.

The engineering problems: automated homography with unknown camera intrinsics/extrinsics, temporal tracking through heavy occlusion, and multi-view sensor fusion.

We do not want a 50-person engineering org. We want a highly elite and specialized team to outperform massive legacy organizations.

You will own the zero-to-one architecture of our perception pipeline. We just hired an Active learning expert from the self driving car space who you will work closely with.

You must deeply understand projective geometry, representation learning vs. pixel reconstruction, and how to build robust active learning loops.

We compensate at parity with tier-one AV companies (Tesla, Waymo) for this role.

Location: Anywhere. Required to come to Troy 1-2 weeks per quarter (which we will pay for). Required to take meetings when needed during Eastern Time hours.

If you are a high-leverage operator who wants to build complex spatial architecture that actually sees production on day one, apply below:

I'm Kris, a manager on Access Control at Verkada.

Access Control is a core product at Verkada. We build the systems that power how customers secure and manage their offices, schools, and campuses. Our software unlocks nearly 8 million doors every day. These are mission-critical systems, not internal tools, and reliability and usability matter a lot.

My frontend team builds more than small widgets or forms. We design and deliver entire workflows that bring clarity to complex systems - managing doors, groups, schedules, users - all within a unified, elegant interface. This means working closely with world-class designers (and debating them when needed), but also having the vision and technical depth to lead when design resources are scarce.

I'm looking for a React expert who can bridge craft and leadership: - Lead technically within the frontend team, setting patterns and guiding others. - Collaborate deeply with our web infrastructure and component library teams to shape the building blocks of our platform. - Champion UX - because building secure, intuitive experiences at global scale is as much about design empathy as it is about React/Redux mastery.

This is a team for engineers who want real ownership, visible impact, and problems rooted in production reality. Verkada is pre-IPO with a $5.8B valuation, and the entire engineering org is about 350 people, which keeps scope high and teams relatively autonomous.

Technologies: Distributed systems, database architecture, F1/Spanner, infrastructure scaling, technical debt triage

Résumé/CV: https://www.linkedin.com/in/joebar/

Email: joe@barrera.org

Distributed systems architect. 30 years building infrastructure at CMU, Microsoft Research, Google. I help startups (10-100 people, Series A-C) avoid catastrophic scaling mistakes. I'd rather prevent your outage than debug it.

What I've built: Mach kernel at CMU under Rick Rashid. Research systems at Microsoft BARC (Gordon Bell, Jim Gray). 9 years on F1/Spanner at Google. 4 USPTO patents in distributed systems.

What I'm good at: "Your database architecture will fail at 10x scale, here's why and here's the fix." Technical debt triage with limited resources. Pattern recognition from decades of catastrophic failures. Currently thinking about LLM verification architectures and why static alignment is the VLIW of AI safety.

What I'm looking for: Fractional CTO or senior advisory role (20-30 hrs/week). Series A-C, 10-100 people, real infrastructure problems.

Looking for experienced engineers to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >30% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).

You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.

We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.

If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* our CTO is the founder and still writes code

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Alterdd is building the fit intelligence layer for fashion. Currently, brands lack structured data on how their products actually fit real customers, making it a massively costly problem. We are fixing this by helping brands understand their fit so they can sell clothes that fit correctly the first time.

We are looking for our first technical hire to take full ownership of our engineering, moving our technology from prototype to production.

Why this role is interesting:

This is specifically designed as a bridge for a hungry Senior Engineer who is ready to step up into a Lead role. If you want the autonomy to build both the product and underlying systems from the ground up without waiting for direction, this is your shot to earn that Lead title. You will work directly with the founder with zero layers between idea and execution.

What you will do & stack:

- Design and build scalable systems across frontend, backend, and data layers. - Stack: Full-stack applications using TypeScript, React, Node, Python (or similar). - Data: PostgreSQL , building pipelines to ingest product feeds and fit data. - Integrations: Embedding our tech into e-commerce platforms like Shopify. You will need to design systems that handle highly inconsistent product and sizing data across different brands.

Working style & Interview: Hybrid working (2-3 days a week in person) in London or Cambridge. The interview process is fast and respects your time: one online technical interview, followed by one in-person interview with the founder.

To apply, please reach out to tech[dot]jobs[at]alterdd.com

Building an AI-powered iOS app that helps professionals make better daily decisions about fueling, movement, recovery, and schedule - timed to their real-world context (calendar, biometrics, personal history), not generic advice.

The technical challenges: HealthKit data ingestion across multiple biometric signals, real-time context assembly for LLM reasoning, a predictive model that combines multiple physiological inputs to forecast the user's state forward, and a server-side pipeline that turns all of this into one actionable recommendation at the right moment.

Stack: Swift/SwiftUI, Supabase (Postgres + Auth + Edge Functions), Claude API. AI coding tools (Cursor, Claude) are core to how we build.

You'd be engineer #1. No legacy code, no inherited decisions. You shape the architecture from the first commit. Looking for someone who's built from zero before, is strong in Swift/SwiftUI, and comfortable owning the full stack including backend. HealthKit experience is a strong plus.

We build a SaaS to extract data from complex platforms like Shopee. They use heavy obfuscation & anti-bot systems, and our job is to break them.

We are working on a deobfuscator that turns obfuscated JavaScript into readable code. It behaves like a decompiler:

- restore strings (e.g. `f(42)` → "my-string")

- simplify control flow (`a && b || !a && c` → `if (a) { b } else { c }`)

- unpack sequence expressions (`var a = (c=1, b=1+c, 3+b+c)`)

- decompile a custom bytecode VM (70K instructions)

This is not typical web/backend work. The target platforms evolve constantly.

We're looking for someone who:

- enjoys understanding complex systems by experimentation

- is comfortable with partially understood code

- has built non-trivial tools (parser, interpreter, RE tool, etc.)

You will:

- own the deobfuscator

- work directly with the founder

- have time to go deep (long-term problem)

https://dqc.ai/careers/senior-software-engineer-backend

We're building the AI-powered platform for enterprise data. Automatically analyse data quality, automatically fix and enhance data, and prevent bad data. Our platform automatically detects issues in master and transactional data, generates improvement suggestions using AI and human expertise, and prevents problems at the source — across systems like Snowflake, Databricks, SAP, and more.

*The problem we're solving*: Bad data costs businesses millions. Rules get written manually, issues get caught too late, and fixes are slow. We're replacing that with agentic AI that generates data quality rules, finds anomalies, and drives corrections (!) yes, it automatically fixes the broken data — with humans in the loop where it matters. Our customers across industrial goods, energy, automotive, and healthcare are already seeing real results.

*About us*: DQC is a Munich-based AI startup founded in 2022. We're a small (15 ppl), fast-moving team where engineers have real ownership and direct impact on product direction and technical architecture. Short decision paths, no bureaucracy, steep learning curves.

*The role*: As a Senior Backend Engineer, you'll own the full lifecycle of feature development — from architecture and design to production deployment. You'll work cross-functionally with backend, frontend, and product to ship features that thousands of users rely on. Our platform sits at the intersection of backend systems, modern data stacks, and LLM-driven workflows, so you'll be building at the frontier of what's possible with AI in production. We practice agentic coding daily and our tech interview includes a live agentic-coding exercise — we want engineers who embrace these tools with judgment, not hype.

If you want real ownership, direct product impact, and the chance to build at the intersection of backend engineering and AI — let's talk.

Build is a full-stack cloud platform — we own the stack from bare metal up. Our customers are engineering-led SaaS teams who've outgrown their current setup and want effortless deployment, real environments, and predictable pricing without the infrastructure overhead.

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.

We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.

Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.

What we're looking for:

3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.

What you get:

Meaningful early-stage equity (not a token option grant)

Direct access to founders and decision-makers, no layers

A say in the technical architecture from day one

Relocation to Miami fully covered

Health, dental, vision

Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.

Email: ksantos --at--direzzefamilyoffice.com, subject line "HN April 2026" so I can find you.

Our intention is to build one of the largest real estate companies in the world, and to be the most technology-native real estate owner in history.

We are hiring a Founding Engineer (Full-Stack) to design and build our proprietary technology stack from inception. You will own the development of our tech stack and have significant autonomy to build. Experience with Python, React / TS, LLM APIs, data pipelines, Ruby, Ruby on Rails, web scraping and entity resolution are relevant.

Cash compensation of $250K - $350K with meaningful equity compensation as the Founding Engineer of a new business.

We'd like to feed the world through AI, here is our product concept:

https://taonexus.com/publicfiles/mar2026/render%203-2.webp

https://taonexus.com/publicfiles/mar2026/render%204.webp

We currently donate money to food banks and would like to set up end-to-end infrastructure so we could deliver free food to people's homes. Our concept is that AI does all the work (including farming) and gives away free goods and services. Where this runs into problems is the question of who's going to make and distribute food and how people are going to get it. While we haven't figured out all parts of food delivery we'd like to work on the distribution channel. We think it's very important.

What we're looking for is someone who is passionate about owning network infrastructure in people's homes and would like to help run the software stack, since at the moment AI is not talented enough to autonomously run the full infrastructure stack. This is an unpaid volunteer position.

What you would be in charge of is food distribution algorithms, equality, fairness, and the long-term future for humanity.

You can email me directly at: rviragh@gmail.com - please mention relevant volunteering or organizations you support.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Mixpeek is multimodal AI infrastructure — we turn unstructured content (video, images, audio, documents) into searchable, programmable assets through a unified API. Think of us as the data infrastructure layer that sits between your raw media and your AI applications. If you've ever tried to build a pipeline that extracts features from video, makes them retrievable, and serves them at scale — you know this is a 12-18 month infrastructure project. We compress that to an afternoon.

We're currently building MVS (Mixpeek Vector Store) — a distributed vector database built on Ray + S3, designed to handle 100B+ vectors at a fraction of the cost of existing solutions. Architecture details: shard-level WAL, LIRE-based adaptive search, replica sets, and agent-native query primitives. If you've ever wanted to rethink how vector search works from the storage layer up, this is that project.

Some things we're shipping right now:

- IP safety for media & sports — our copyright detection platform (https://copyright.mixpeek.com) helps brands and leagues detect unauthorized use of visual IP at scale. We're working with partners in the media/sports ecosystem including Backblaze for storage-native integration.

- Healthcare pipelines — multimodal extraction for clinical trial recruitment and SNF/MDS coding workflows, working with enterprise partners in the space.

- Ad verification — we contribute to the IAB Tech Lab ARTF working group and power contextual intelligence for ad safety.

Our core primitives: feature extractors, retrievers, taxonomies, clusters. Decompose with extractors, recompose with retrievers. Docs: https://docs.mixpeek.com

Stack: Python, Ray, S3, FastAPI, React/TypeScript. We also maintain amux [https://github.com/mixpeek/amux], an open-source tmux multiplexer for running parallel Claude Code agent sessions — if you're into agentic dev workflows, check it out.

I'm Ethan (founder/CEO, previously led search at MongoDB). Small team, high ownership, real problems. We're preparing for NAB Show next week and scaling enterprise pipeline work across healthcare, adtech, and media.

Hi, Alex and Jeremy here from UMH.

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.

What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.

Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.

We just announced our $42M Series B last week! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

(Hear from our CEO here: https://www.shepherdinsurance.com/blog/behind-our-42m-series...)

(Hear from our CTO here: https://www.shepherdinsurance.com/blog/the-road-to-autonomou...)

This year, we’re doubling our engineering team from 20 to 40. We’re looking for product-minded engineers to join us as we continue to scale! We’re looking for someone who thrives on ownership, drives results, and cares deeply about both technical excellence and customer impact.

We’re hiring various mid-level, senior-level and staff-level engineers. See some of our openings below:

At Volcore, we model the electricity system to do proprietary trading that helps balance the grid and facilitate renewables integration. Our technical roles are a blend of Software Engineering and Data Science, wherein we solve problems end-to-end, from data ingestion and analysis to optimisation and deployment. Often these require novel solutions, drawing on original research and experimentation. We are a profitable and ambitious scale-up looking for people who can both crack these kinds of problems and continually improve our shared libraries, tooling and workflows to ensure they are fast, accurate and a delight to work with.

Our team are close-knit, with minimal hierarchy and almost zero meetings. We work together in-office to whiteboard solutions together and everything we build is used by people sitting next to us.

Typically these positions attract talented people looking to build a career out of solving challenging computational problems; and/or people who have outgrown their previous role and are seeking more responsibility or more challenging subject matter. Every team member owns important projects very early on, and if you can deliver value in a particular area, you’ll be recognised and rewarded for it, regardless of job title.

Our tech stack includes Python, backend Typescript, Postgres and Rust.

We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.

Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.

Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.

We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.

Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.

Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).

Please email us at jobs@kinelo.com. If you want to stand out, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009

We are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted.

Most of the software engineering positions have been repeating here for years because we've been continually hiring for them, scaling our whole team to now over 300 people—many of those hires have come through Hacker News. We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

We build real-time civilian threat intelligence for conflict zones — and we just landed our first operational pilot. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G.

This is not a pitch deck. We have a working system: Django backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts. Since our last HN post: 93 candidates vetted across two months, 1 Senior AI/Backend Engineer hired (now owns the verification pipeline), and we've begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation).

*We need one person:*

*Founding Product Engineer / Systems Architect* You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. Our AI pipeline lead handles the Gemini orchestration — your job is to own the data layer, build the API surface, and wire it directly into the offline-first client. This is not drawing backend diagrams. You must be an end-to-end builder who cares about how a civilian interacts with the system on the ground in a crisis. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone.

Must have: Python/Django, MongoDB, Flutter (or high competence to pick it up fast), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial.

We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack.

*Compensation (No BS):*

- Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity. - Seed (6-12 months): 75% market salary + equity. Increases from there.

If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk.

*Stack:* Python 3.9+, Django 4.1.13, MongoDB, Flutter, Vertex AI (Gemini 3 Pro Preview / 2.5 Flash / 3 Flash Preview), Docker, AWS.

*Apply:* Email PeterJFrancoIII@gmail.com with subject line `[SENTINEL-BUILDER] - HackerNews Application`. To prove you read this, include the word "Atlas" in your first sentence. Include your Resume or GitHub + what you'd build in your first week. (Emails without the exact subject line are auto-archived.)

We have roles open for a principal software engineer:

We're looking for a Principal Software Engineer to join as a founding engineer. You'll work directly with the founders to build the core of our agent security runtime. This is a high-autonomy role - you'll shape architecture, engage with early customers, and make the trade-offs that define the product.

You will build the layer between agentic reasoning and system execution — intercepting, classifying, and validating every agent intent against security policy before it runs. Design systems that capture and cryptographically verify every instruction and action, maintaining ground truth in environments prone to hallucination and injection. Architect fine-grained, time-scoped primitives that allow least-privilege permissions, with the ability to escalate under controlled, auditable conditions. Work with research to stress-test our security primitives at scale. Turn emerging threat vectors (prompt injection, tool misuse, privilege escalation) into adaptive defences.

Staff solutions engineer:

We're looking for a Solutions Engineer join as a founding engineer and to sit at the intersection of our open source community and our growing base of enterprise design partners. You'll spend your time contributing to Nono, helping shape its architecture, and working directly with customers who are integrating it into proof-of-concept and pilot programmes. This is a hands-on role - early on you'll be deep in the code, reviewing pull requests, triaging issues, and experimenting with deployment architectures, all while being a trusted technical voice for both community members and enterprise stakeholders. Over time, the role will evolve toward solutions architecture and customer-facing engagement, as you build the domain expertise and relationships that make you the go-to person for designing how Nono fits into complex enterprise environments.

What You'll Do" Contribute directly to the Nono open source project - code, documentation, and architectural proposals. Experiment with different deployment architectures for Nono across cloud environments, on-premise infrastructure, and hybrid setups and share your findings with others at Always Further, and often with the community, via our blogging platforms or YouTube channel. Work closely with early design partners to integrate Nono into proof-of-concept and pilot programmes, gathering feedback and translating it into engineering priorities. Produce technical content - blog posts, architecture guides, demos.

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.

Tech stack: Angular moving to React | Node / Bun | ECS | Mongo | Snowflake

Small team doing big things.

We've taken the team AI native, the platform will be there withing a few months. An existing v1 platform built with "boring" technologies allows us to make sure money and data remain safe whilst ensuring the frontend can be built at the speed that AI enables.

One of our team is taking everything they've been playing with for the last couple of years and stepping in to a YC principal role with our blessing. We're looking for their replacement to help continue bringing the team to the same level.

We've spent years creating the brand advocacy category, and are now seeing huge growth in all areas. We took Series A last year, are seeing massive growth, and still finding the time to have fun.

You need to back yourself. We'll expect a lot form you, but you'll be given the autonomy you need to do your best work. We focus on hiring bloody brilliant, utterly lovely people.

No recruiters. The role is being opened as we speak (I'm on holiday, spotted the who is hiring!); for now, please reach out to: joe via duel.tech.
