American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

Competitive salary, flexible working environment & location, if you are interested, feel free to email: ayeeye.careers@gmail.com (subject: “HN – Role”)

Modern hardware supply chains run on spreadsheets, email, and PDFs. It's like fax woke up in 2025. We're fixing this with an AI-first procurement platform for aerospace, defense, and nuclear manufacturing.

Our customers: Machina Labs, Astranis, K2 Space, Castelion, Antares, and more. They use us to manage suppliers, track $M+ in orders, automate RFQs, and stay ITAR-compliant. Every day of production delay costs $50k+—our platform keeps them moving.

The role: Own features end-to-end, build ERP integrations that sync POs and manufacturing data, real-time order tracking dashboards, and a user experience that people LOVE. Work directly with customers whose supply chains depend on what you ship.

Stack: TypeScript, React, Next.js, Hasura (GraphQL), PostgreSQL, Trigger.dev, AWS GovCloud, Pulumi, Elbow grease.

You: 5+ years shipping production systems, strong full-stack or frontend generalist who moves fast, thrive on customer feedback and direct impact, bonus: ERP integrations, B2B SaaS, or regulated industries

Traction: 5x'd customer count last year, $5M funding to date, landing massive defense/space logos. Small team shipping incredibly fast—you'll work directly with our founders (Isaac and myself).

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

Senior IC role, report to me directly.

You'll need to bring real world experience from designing and running systems that really matter, a true "full stack" mentality (from UX deep down into the DB), team-spirit, and have worked in the EU before. We'll provide: Colleagues who are not only highly competent but you'll actually enjoy working with, 3-2 onsite/home-office model, great office in the heart of beautiful Hamburg, latest Macbook, excellent e2e/integration testing setup, pseudomised customer DB dumps for realistic development data, completely cloud-agnostic, "airplane mode" (you can spin up a full dev environment locally and without internet!), Open Telemetry, and more.

I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.

I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FPGA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.

I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.

What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

Osaurus is a native macOS AI platform. The core idea: inference is a commodity — everything else (context, memory, tools) should be owned by you, locally. Think of it as the runtime layer for AI on Mac that works with any provider (OpenAI, Anthropic, xAI, local models via MLX).

3.7K+ GitHub stars and 54K+ downloads with zero marketing spend. Open source, local-first, provider-agnostic.

Looking for a protocol engineer who wants to build agent-to-agent networking and communication infrastructure. You'd be the first hire.

What we work with: Swift, macOS native APIs, Apple Silicon optimization, provider-agnostic API layer, plugin architecture. You don't need Swift experience specifically — strong systems fundamentals and the ability to pick things up fast matter more.

If this sounds interesting, try the app (https://github.com/osaurus-ai/osaurus), share your GitHub, and tell me what you'd change.

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

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.

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. 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.

* 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 hopefully be the first to know about it.

We’re hiring 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 building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

Neoteny AI is building the sovereign intelligence layer for code. We are a team of builders from Meta, AWS, and NYU who believe that the future of coding intelligence is not a generalist chatbot in the cloud, but a specialized, repository-aware model that lives inside the enterprise perimeter.

We are looking for a founding researcher to lead our core research agenda. You will work at the intersection of representation learning, program synthesis, and efficient inference.

You will figure out how to teach models the latent physics of a codebase, the implicit architectural rules, dependency patterns, and style constraints that generalist models miss. Your work will range from designing new data engines to experimenting with novel architectures that break the memory wall of current transformers.

We are looking for someone with deep ML expertise (PhD or equivalent) who is code-fluent and comfortable writing kernels, not just training scripts.

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 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.

Adobe is building a Real-Time Customer Data Platform (CDP) that operates at a scale most companies never see. We aren't just building another "enterprise app"; we are managing trillions of events and solving complex state problems in real-time.

If you find "distributed systems" a lifestyle rather than a buzzword, we want to talk. We are currently tackling challenges in high-throughput streaming, identity resolution at scale, and sub-millisecond data retrieval.

The Stack:

Core: Java, Scala, Spring Boot

Compute/Stream: Spark, Flink, K8s

Storage/Messaging: Kafka, FoundationDB, Aerospike, Cosmos DB, Delta Lake

Infrastructure: Multi-cloud (Azure/AWS), Docker, Vector DBs

What we’re looking for:

The "8+ Years" Profile: You’ve spent a decade breaking and fixing large-scale distributed systems.

Concurrency & Performance: You don’t just write code; you tune it. You understand the JVM, memory models, and how to squeeze performance out of every thread.

Architecture: Experience with Flink/Kafka/Spark isn't just about using the API—it's about knowing how they fail and how to keep them running under massive load.

The Logistics:

Locations: San Jose, New York, or San Francisco (Hybrid/Onsite).

Comp: $177,900 – $257,550 base + Equity + Adobe’s notoriously good benefits.

At Constellation, we are building a future where technology is the lethal advantage in credit investing.

Credit documents govern everything from how much debt a company can incur, or pay in dividends, to what they can do with proceeds from selling assets. Hidden debt capacity, loosely drafted provisions, or ambiguous definitions can materially alter recovery, making precise covenant interpretation essential to investing outcomes.

Constellation makes it easy to read credit documents, calculate covenant capacity, and plan liability-management transactions, reducing the mechanical bottlenecks to analyzing credits and generating alpha.

Our team is comprised of subject matter experts who have spent a decade in credit (Goldman Sachs/Citadel), AI/ML researchers, and full-stack engineers who are dedicated to solving frontier problems in their application to the world's largest asset class.

We recently raised a $3.25mm round led by Haystack and Company Ventures. We are hiring for these roles: https://www.constellationfinance.ai/#/careers

Generation Alpha Transistor (Gen-Alpha) is a San Francisco based start-up, building AI tools for chip designers. It's a space that’s gaining enormous momentum as demand for AI silicon keeps growing.

We’re looking for talented software engineers and language-agnostic developers to join our rapidly growing team, collaborating in-office with the founding engineers. We are a small, all-technical team with PhD grads from Berkeley, MIT, and Carnegie Mellon with extensive tenure in companies like Apple, Amazon, Synopsys, and Cadence. This role will also have direct exposure with customers who are some of the world’s biggest and highest-impact semiconductor designers and fabs.

If you are interested, please send your resume along with you some upcoming availability to henry@gen-alpha.io. If there is a potential fit, I can help get a call set up with you and one of our founding engineers to talk more about the opportunity!

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, 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.

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.

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 Balderton, XTX Ventures and leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

Transfyr is building physical AI for science.

Why is it that a professional athlete has dramatically more information about every play they make than a scientist has about the cause of any experimental failure? At Transfyr, we are building the infrastructure to make real-world scientific work legible, transferable, and reproducible.

Modern science is capable of extraordinary outcomes, but much of the most important insights never become explicit: how experiments are actually executed, protocols drift, how experts make gametime decisions on the fly, why experiments fail on Tuesdays. This tacit knowledge is rarely captured, making it difficult to reliably reproduce results, much less hand off protocols to new team members or collaborators. We believe our systematic failure to capture tacit knowledge is holding back the entire industry.

We’re building systems that operate directly in real laboratory environments to elucidate, capture, and interpret this missing information. Our platform records and analyzes multimodal data about how scientific work is performed and turns it into durable, operational knowledge. In doing so, we are also building the world’s largest commercial dataset on real-world scientific execution.

This foundation is critical not only for driving elite human performance today, but for enabling meaningful automation tomorrow. Physical AI systems cannot learn from outcomes alone; they require rich, grounded records of how work is actually done in the real world.

Key domains of expertise we’re looking for (hiring from entry level to senior leadership):

- Computer Vision: take messy real-world images and video and make sense of them

- AI / ML Research & Engineering: build the best digital brains to support the best physical brains on the planet

- Full Stack Engineering: integrate our AI and data into tools that solve real customer problems.

A change from when I posted here previously: we are now focused on on-site in-person roles, at our lab/office in Cambridge, MA. And, we are particularly interested in DevOps/backend experience for the full stack role.

If you're interested, apply here! https://transfyr.ai/join-us

Fullstack Developers

You'll work across the JavaScript and TypeScript layer of our local AI stack. Depending on the project, you might build user-facing applications (mobile or desktop) or contribute to the platform layer that bridges our C++ inference engines with the app ecosystem. Either path puts you at the heart of making local AI usable: whether you're crafting polished product experiences or building the SDK and bindings that other developers rely on. This role suits engineers who thrive in a full-stack JS environment and want to be part of a system where AI runs privately, locally, and fast.

Strobe is building the world's largest power plant — not a single site, but a distributed fleet of buildings, batteries, EVs, and generators buying and selling power in real time across wholesale energy markets.

We need a senior engineer to own our data integration and cloud infrastructure layer — the connective tissue between utilities, grid operators, OEM hardware, weather services, and our optimization engine.

What you'd own:

– Wholesale market integrations (NYISO, CAISO, ERCOT) — real-time pricing, capacity markets, demand response signals

– OEM hardware integrations — API and data bridges to building equipment manufacturers for monitoring, control, and telemetry

– Green Button Connect pipelines — ingesting interval consumption, billing, and meter data from utilities (ConEd, PG&E, SCE, etc.) via OAuth2 + ESPI

– Weather and solar forecast data pipelines

– Utility bill reproduction engine — modeling site economics before and after Strobe to forecast financial impact across dozens of rate structures. This simulation infrastructure is core to how we sell and deliver value.

– Event-driven AWS infrastructure (Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, TimeStream, Amplify, CloudWatch)

– Terraform IaC — real module design, remote state, multi-workspace patterns

– Observability and alerting on systems where downtime means missed market events and real dollars

Strong fit if you have:

– Deep AWS experience (IAM, Lambda, API Gateway, AppSync, EventBridge, TimeStream or similar TSDB)

– Production Terraform (modules, remote state, multi-workspace patterns)

– Extensive Python (pydantic for models, click for CLIs, boto3 for AWS, async pipelines)

– Experience integrating messy third-party APIs at scale (utilities, government, energy, OEMs)

– Comfort with on-call for systems that control physical hardware and move real money

Stack: Python / TypeScript / Rust / Terraform / AWS / GraphQL (AppSync) / MQTT / Grafana — AI-agent-optimized monorepo with deep investment in agent-enabled engineering efficiency.

Small team, high ownership, no layers. 5 days/week onsite at Newlab, Brooklyn Navy Yard.

We're a mental health 501(c)(3) nonprofit building a care navigation platform – think "find the right therapist" but across every type of mental health treatment – with insurance awareness and consumer-aligned privacy baked in. Small team, startup pace, mission that matters.

We're an AI-native team – actively experimenting with the best ways to leverage AI in how we build, not just what we build. LLM-powered data enrichment workflows, agent coding teams, the works. You'd own a significant chunk of the architecture and ship across the full stack: NestJS backend, Next.js frontend, data pipelines for provider and condition data. You'll shape eng culture and hiring as we grow.

What we're looking for: someone who's startup tested and ready to be the first FT eng hire in the office. Comfortable making architecture calls and still writing code daily. Experience with data-heavy consumer products (search, marketplaces, health tech) is a strong plus. https://jobs.lever.co/project-healthy-minds/514c5d68-8e18-45...

*Who we are*

We're reimagining what mortgage underwriting looks in a world where engineers and operators gain leverage through the use of modern agentic AI. We're at the forefront of using AI tools to hack our own workflow, but also to build automation and tools for our clients.

We currently work with 8 of the top 20 mortgage lenders in the country. NewRez lending, a publicly-traded, top-5 lender recently selected us to be a cornerstone of their AI underwriting strategy, calling this out on their last quarterly earnings call.

https://www.newrez.com/press-news/strategic-ai-investment-in...

*Who You Are*

While we have a number of roles, we're primarily looking for a specific attitude: talented, motivated individuals who tolerate ambiguity and can bridge the gap between business uses cases and engineered solutions. We believe that modern AI tools bring a great deal of leverage to engineers and we're motivated

We're looking specifically for engineers who can work directly with me (CTO/Co-Founder) and a small group of of SF-based engineers/PMs. In particular looking for a strong Frontend/Design engineer, along with a backend engineer.

We've hired from HN in the past and are excited to keep going.

I'm and old time programmer, almost retired now, want to stay anonymous here. Will do supervising and project management for this job.

Looking for X86 reverse engineer with good experience of C decompilation, knowning modern tools like Reko, Ghidra, BNinja and such, maybe with AI.

Have a few projects to do, quite esoteric. Can support your own projects for old games or other software. Salary is negotiable per project and agreed KPI, like 50K-100K USDT for around a month-long project.

Weekly progress towards agreed goals is expected, with payments due after results reviews. Mostly async communications. Please mail your free form introduction to mcm10000@gmail.com with words "decompile job" in subject.

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.

See our roles here: https://jobs.lever.co/sprucesystems/

Senior Software Engineer: You'll own complex technical problems end-to-end—translating customer needs into scalable architecture, optimizing AI model efficiency through prompt engineering, and shipping features that directly impact how revenue teams operate. We want bold ideas and people who push boundaries.

Junior Software Engineer: You'll work across our stack (Python, FastAPI, Next.js, React) alongside senior engineers, contributing to real features from day one. Great fit if you're hungry to learn, ship fast, and grow with a startup building cutting-edge agentic systems.

New Grad Software Engineer: Entry point for recent grads excited about AI and agentic systems. You'll get hands-on experience with our modern data stack (Postgres, ElasticSearch, ClickHouse, DuckDB), Kubernetes/AWS deployment, and Temporal.io workflow orchestration while shipping production code.

This role is based in our Manhattan office (4 days/week in-person). Full health and dental coverage.

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us

Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.

Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).

Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.

Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.

The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers

But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.

That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/

As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.

Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com

Ever wanted to build indie video games at a startup? Let's talk. Elsewhere is a San Francisco-based company building a new kind of multiplayer social video game, inspired by indie roguelike deckbuilding games like Slay the Spire and CCGs like Magic: The Gathering. We're using generative AI in a creatively interesting way to build the first AI game that doesn't suck. We're backed by top Silicon Valley investors, and graduated from the first cohort of a16z's SPEEDRUN program, which is kind of like YC for games.

Ideally, you:

* Have worked as a software engineer before, ideally on a small team.

* Have built and shipped games before, either professionally or on your own time.

* Have experience with full-stack web development, using TypeScript, React, etc.

* Love games yourself, and have always wanted to work in the games industry.

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.

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.)

Support Engineer - If you want to use Claude or Codex (or Shelley!) to trawl through our code base, augmented with (carefully scoped) API keys to make our customers lives better, we are hiring.

Designer - If you want to use Claude or Codex (or Shelley!) to make our product functional and beautiful, we are hiring. You do not ship mocks or assets to other teams. There is no other team. You ship by pushing to production. Don't worry, we've got your back.

Software Engineer - If you see a pattern here, we are hiring. Expect to design, build, and run entire subsystems. What matters is attention to product detail and overall architecture, we have agents for writing code.

With significant industry experience, pay will be over $200,000 with meaningful equity.

We are a small team and going to stay one. The focus is building a high-trust environment. Success for us is if you say "I'm going to fix the load balancer" we all sigh with relief, because you are on it and we can rely on you to take on and solve large projects.

By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production.

Apply Here: https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email Jason.dupree@baseten.co

We are hiring for multiple core roles:

1. Solution Architect: You will partner closely with sales and customers to translate business needs into technical solutions, run technical discovery, and guide repeatable deployments and proofs of value for customers. This role is a great fit for entrepreneurial, customer-facing technical professionals who want a front-row view into how modern companies adopt AI at scale, and who enjoy working across technical discovery, solution design, demos, deployment scoping, and hands-on customer implementations, in close partnerships with Sales and Engineering

2. AI Solutions Engineer/Forward Deployed Engineer: You will partner directly with customers to architect, build, and deploy high-scale production AI applications on Baseten’s platform. You’ll own the journey with customers from initial exploration to production deployment. To be clear, this is a technical engineering role with hands-on coding and software dev that also includes aspects of product management, technical customer success and pre-sales solutions engineering mixed in. We’re language agnostic but strong Python and ML experience is a big plus.

3. Forward Deployed SRE: You will serve as the primary post-sales technical owner for our most strategic customers, ensuring smooth deployment, performance, and reliability of ML workloads in production. The role blends hands-on debugging, infrastructure expertise, AI model performance, and executive level customer facing ownership. We’re looking for deep Kubernetes and container orchestration experience along with a polished communication and executive level presence.

The Offer:

Compensation: Very competitive, we’re looking for folks with a breadth of experience

Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform

Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.

Process: If you’re interested, please apply here https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email me direct at Jason.dupree@baseten.co

I'm looking for a software engineer to be our head of Strategic Finance. In addition to modeling our revenue streams in Excel/Sheets, we make heavy use of Claude Code to create tools to track popular titles, store charts, basically any data we can use to understand the gaming market. We then use that data to determine the direction for the company.

Reasons you’d love working with us:

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

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.

Hi HN. I am an Engineering Manager at Nectar Social, and we're hiring across product, design and engineering.

The traditional playbook of buying ads on social media platforms no longer works for most brands. Buyers make purchasing decisions from organic conversations on social media platforms like Instagram, Reddit, X, and LinkedIn. Nectar listens to conversations in real time, surfaces actionable insights, attributes engagement to revenue, and drives conversions.

We came out of stealth last year and we are on a fast growth trajectory working with brands like OLIPOP, Hatch, K18, and Little Spoon. The company is ~30 FTEs and has many interesting challenges:

1. We ingest data from major social media which brings scaling and performance problems

2. We run AI agents on the content which requires us to control cost and optimize quality

3. We need to present lots of information about social conversations in an understandable way which requires good design.

4. We need to build resilient systems that can work within the constraints of our third party dependencies.

Our tech stack is React, Typescript, AWS, Pulumi, Postgres, Clickhouse and Turbopuffer. We use AI tools thoughtfully to optimize our daily work - Cursor, Claude Code, Graphite, v0 / Replit, and Granola.

The roles we are hiring for:

- Staff Backend Engineer - https://jobs.ashbyhq.com/nectar-social/e5797dfd-275e-4a7a-b9...

- Staff Product Engineer - https://jobs.ashbyhq.com/nectar-social/2f942c62-bc21-41a2-ae...

- Founding Mobile Engineer (React Native) - https://jobs.ashbyhq.com/nectar-social/192caa1d-8f36-472f-b9...

- Senior Product Designer - https://jobs.ashbyhq.com/nectar-social/673bbd54-9a3b-4478-84...

- Senior Product Manager - https://jobs.ashbyhq.com/nectar-social/b63c6254-df3d-406e-83...

Please email careers@nectarsocial.com with "HN" in the subject line if you're interested.

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.

Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.

We’re looking for:

- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)

- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)

We can’t sponsor visas but relocation assistance to SF is possible.
