We work with robots that run biology experiments. The robots are accurate, but programming them by hand takes so long that most labs don't bother. So we wrote a compiler and visual editor a scientist can use. They describe their protocol in plain language, we parse it into a structured format, and compile that to optimized code. Our end goal is to build the infrastructure for autonomous science and a centralized cloud lab. Short demo: https://tinyurl.com/mrx63phb
The team is three software engineers, an automation engineer, the founders, and soon a designer. The codebase is one monorepo containing an OCaml compiler, Python backend services, and a TypeScript/React editor. The challenges come in the form of eliciting scientific context and tacit knowledge and in the fact that a protocol has to deterministically run correctly.
We are looking for at least 3 years of experience. OCaml isn't a requirement, just a willingness to learn it. Nice if you've done DSLs, compilers, life sciences or lab automation, an ML-family language, or LLM parsing and evals.

Aquabyte is on a mission to revolutionize the ocean sustainability and efficiency of aquaculture. By making fish farming cheaper and more viable than livestock production, we aim to mitigate one of the biggest causes of climate change and help prepare our planet for impending population growth. Aquaculture is the single fastest growing food-production sector in the world, and now is the time to define how technology is used to harvest the ocean for generations to come. Through custom underwater cameras, computer vision, and machine learning we are able to quantify fish weights, detect sea lice infestations, and generate optimal feeding plans in real time. Our product operates at three levels: on-site hardware for image capture, cloud pipelines for data processing, and a user-facing web application. As a result, there are hundreds of moving pieces and no shortage of fascinating challenges across all levels of the stack.

One of our customers has thousands of packaging assets spread across dozens of markets, languages, regulations, and brand standards.
Every change needs to be reviewed before launch. Humans currently do most of that work.
We are automating it. The challenge isn't generating text. The challenge is building systems that can be wrong almost never.
We're looking for:
- Forward Deployed Engineers who enjoy sitting with customers, figuring out what's actually broken, and building solutions faster than a roadmap ever could.
- Applied AI Engineers who obsess over retrieval, evaluation, orchestration, reliability, and all the ways AI systems fail in production.
Small team. Real customers. Revenue. Lots of difficult edge cases.

Today we use ML to make data warehouses and spark jobs more efficient. We're hiring staff ML engineers to train models that can understand how much compute a job needs, how it scales to larger machines, whether a machine can run more jobs, and so on; and staff infra engineers to take those models and deploy them on real-world production systems.
We're also looking for FDEs who can help us talk to users and run pilots. This is a pretty technical role (you need to be able to do data analysis and debug in prod) that's also user-facing - it should be a good fit for a former (or future) technical founder.
If this sounds cool, please email me: alexis [at] espresso [dot] ai
We're building Tenki — Luxor's compute platform. It started as internal runner infrastructure, now powers code-review agents and isolated agent sandboxes (ADE), and the roadmap extends to agent workflows, background automation, and CPU/GPU compute. If you know what that space involves, you'll understand why our bar is high.
We need someone with real engineering experience who has also built a public technical audience. A GitHub with stars, a blog that's been running for a couple years, a YouTube channel engineers watch, or X threads people argue with. You don't need all of them, but you need something real to show.
What you'll actually be doing: Show up at SF meetups, hackathons, and developer events — be the person engineers meet first when they hear about Tenki
Working side by side with engineering and product teams so you can speak honestly about how things work — and making sure that developer feedback shapes the roadmap Weekly livestreams running Tenki against real OSS bugs Teardown threads on X when a release ships Public benchmarks and honest post-mortems Structure: You'd be the first person in this seat. Small, technical team. No playbook yet — full ownership. We want to grow with and because of you.

Puntt AI is the system of record for enterprise marketing compliance. Our AI agents turn hours of manual brand and packaging review into minutes of automated precision. Danone, Nestlé, and Kenvue are live customers. The product works. Now we scale.
Forward Deployed Engineer | $190k + equity https://wellfound.com/l/2CiVyv
The FDE is the person in the room when an enterprise customer shows you their actual broken process. You run discovery, figure out what's really going wrong, configure and ship against it, and bring that signal back to product in a way the team can actually use. You work directly alongside our CEO in live enterprise cycles. What you learn shapes what we build next.
Best fit: solutions engineering, field engineering, or technical founder background. You've been in enterprise rooms, you get to the real problem fast, and you can build the thing that proves the fix. Full stack, AI-native, 7+ years.
Senior Applied AI Engineer | $185k-$210k + 0.75%-1.25% equity https://wellfound.com/l/2C3WzL
This role owns the agentic core -- multi-agent orchestration, RAG and retrieval, stateful async workflows (Temporal), and the eval frameworks that make compliance AI trustworthy at scale. If you've spent real time thinking about failure modes, observability, and what reliable actually means when LLMs are in the loop, that's who we're looking for.
5-7+ years production engineering. 1-2+ years building with LLMs in real applications. Strong Python. Hands-on RAG.

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.
The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.
A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.
You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.
You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead
Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.
To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.

We raised a $150M Series C at a $1.5B valuation, backed by Khosla Ventures, Sequoia, Blackstone, Insight Partners, NEA, and NVIDIA.
We're hiring across the stack:
- AI Engineer: agentic systems, LLM integrations, evals
- Fullstack Engineer: platform, APIs, auth, billing, terminal UIs
- Frontend Engineer: web and desktop apps (React, TypeScript, Electron)
- Platform Engineer: infrastructure, sandboxing, CI/CD, cloud
- Product Engineer: end-to-end feature ownership
- Data Engineer: pipelines, analytics, telemetry at scale
- Security Engineer / Research Engineer
Stack: TypeScript, React, Node.js/Bun, Python, GCP/AWS, Firestore, Electron.
We're also hiring in these roles: Enterprise & Mid-Market AEs, Solutions Engineers, Forward Deployed Engineers, Product Marketing, Product Manager, Product Designer, Partnerships, and Operations (RevOps, BizOps, People Ops, Recruiting). Some roles available in NYC and London.

Hey HN! I'm Alexander, one of the founders of Hatchet. Hatchet is an open-source platform for running background jobs at scale.
We're hiring engineers who are excited to build the next class of engineering primitives, starting with queues, background tasks and durable execution. We started in early 2024 after launching our distributed task queue (https://news.ycombinator.com/item?id=39643136).
Hatchet is currently used by thousands of engineers for all kinds of workloads: log ingestion pipelines, code review agents, video encoding, GPU scheduling, etc. Our target customer is fast-growing startups who have a strong need for background jobs system. These days, that tends to be AI companies, though we're general-purpose and not exclusively targeted for AI workloads.
Stack: Postgres, Go, Typescript, React, Kubernetes
Applying: email me at alexander@hatchet.run and tell me about something impressive you've built, along with your CV and why you're interested in Hatchet.

AI data centers are creating a massive new wave of electricity demand, and the grid is already stretched. Strobe is building an autonomous power company to help meet that demand: software that turns buildings, batteries, EVs, and generators into a distributed power plant that can buy, sell, and dispatch electricity in real time.
We’re a 6-person, well-funded team backed by top investors. This is early, high-ownership, and very real-world: the software you build will control physical assets and move money in energy markets. We are the only company actively trading distributed power in New York - the space is entirely new and unlocked by recent FERC regulation.
I’m looking for a staff engineer to own the data integrations and cloud infrastructure that make the whole system work. That means connecting to utilities, grid operators, OEM hardware, weather providers, and our optimization engine — then making sure it all runs reliably when market events are happening and dollars are on the line.
You’d work on things like:
* Wholesale market integrations with NYISO, CAISO, ERCOT: pricing, capacity markets, dispatch signals * OEM hardware integrations for monitoring, control, and telemetry * Utility data pipelines, including Green Button Connect / ESPI, interval usage, billing, and meter data from utilities like ConEd, PG&E, and SCE * Weather forecast pipelines feeding our scheduling engine * Event-driven AWS infrastructure using Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, Timestream, Amplify, and CloudWatch * Terraform IaC, observability, alerting, and the reliability work needed when downtime has real financial consequences
Good fit if you have deep AWS experience, have used Terraform seriously in production, and write a lot of Python. Energy experience is a plus, but not required. Experience with utilities, government APIs, OEMs, hardware, telemetry, or other “real world is messy” systems is very relevant.
Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We use an AI-agent-optimized monorepo and are investing heavily in agent-enabled engineering efficiency.
Small team, no layers, high trust.

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.
We're hiring for two roles right now:
- Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market?
- Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast.

Column is building the infrastructure that powers the US dollar globally. We're a software first company, but also own a nationally chartered bank that we've built from the ground up. We're currently processing trillions of dollars annually (yes, that's with a T), supporting some of the largest and most sophisticated companies out there like Wise, Bilt, Brex, Ramp, Mercury and dozens of others.
Started by the founder of Plaid (plaid.com), Column is focused on keeping an extremely lean and experienced team: currently 10 engineers that all report to the CEO (many of whom we hired through HN). We are looking for an ambitious infrastructure, product, and backend engineer (one of each) that want to build incredible software from first principles.
Profitable and 100% owned by employees and founders.

ParadeDB is a Postgres extension that delivers state-of-the-art search in Postgres. Our customers, including Alibaba Cloud, BILT Rewards, Modern Treasury (YC S18), and many others, rely on us to deliver the performance and feature set of dedicated vector databases/Elasticsearch natively in Postgres, simplifying their stack and day-to-day operations.
If you like systems, this might be for you. We're a team of 10, a Series A company based in SF but distributed across North America. We're hiring for database internals work (e.g., building the database in Rust) and distributed systems work (e.g., building the database-as-a-service platform in Go).
We're open-source at https://github.com/paradedb/paradedb.

Caplight is a profitable fintech company reimagining the private markets. We build data, trading, research, and workflow tooling for VCs and other private company investors. We're closing a Series A on the back of strong success with our current platform which focuses on helping late-stage VCs track realtime pricing on pre-IPO companies like Anthropic, Stripe, SpaceX, etc. Our goal over the next year is to build powerful agentic workflows to automate large parts of the VC ecosystem.
Looking for product-minded AGI-pilled engineers. If interested, email me with a short description of your background and why you believe you're right for the role: justin at caplight.com (if you write your email with AI I will not read it)
I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.
Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).
The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.
You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.
We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Gulid.ai is the control plane for agents. We're building a new way of orchestrating and sharing agents that mimics some of the best parts of Github, with the centralized control and credential management that enterprise shops need.
From our about us: We are builders at heart—founders, SREs, open-source stewards, architects of large systems, and people who love creating things from scratch. We believe AI should amplify the creativity of everyone who builds software, not just speed up tasks. If you’re technical, curious, customer-driven, and want to shape how the next generation of software is created, we’d be thrilled to work with you.
We have multiple open roles, including AI Engineer, Forward Deployed Engineer, and Software Engineers.
I’m an Engineering Manager in Security at Chime, and we’re actively hiring for three roles on our broader Product Security org:
Senior Application Security Engineer: https://careers.chime.com/jobs/8373535002/senior-application...
Product Security Engineer: https://careers.chime.com/jobs/8141068002/product-security-e...
Manager - Product Security: https://careers.chime.com/jobs/8526680002/manager-product-se...
Chime is a financial technology company focused on helping everyday Americans unlock financial progress. We built Chime on the premise that core banking services should be helpful, easy, and free, and our security teams play a direct role in protecting the products and infrastructure that members rely on.
Our Product Security org works across application and infrastructure security, security design and architecture reviews, and vulnerability management. We partner closely with engineering teams to identify, prioritize, and remediate risk early, with an emphasis on making security practical, embedded in everyday development, and useful to the teams building Chime’s products. If you’re excited about being on the front lines of securing both AI and financial technology, this is a particularly interesting place to do that work. We currently have Senior Application Security Engineer, Product Security Engineer, and Manager - Product Security open.
If none of those are quite the right fit, feel free to apply anyway! We expect to open more security roles in the near future across a range of experience levels and specializations.
Tenera (https://trytenera.ai) is building the product decision layer for agents and humans, backed by a top tier VC (announcing soon). We help teams validate what they build across the entire software development lifecycle, grounding AI personas in real user behavior and business context, then proving them out by replaying past product decisions.
We are a small, exceptionally talented team (ex-Amazon, Nvidia, Uber, Stanford, CMU) hiring our first engineer. We work onsite in SF five days a week (open to relocation for the right person) and offer meaningful founding equity.
This is an unconventional role. We want an "agent-native" engineer. If you are still writing every function by hand, this isn't for you. You will orchestrate multiple coding agents in parallel, managing worktrees, concurrency, and shared context, while owning the architecture decisions that matter most: big data pipelines, schema design, system tradeoffs, and evals.
Requirements: 3+ years shipping full-stack apps, comfortable with LLM infrastructure and tracing, fluent with git worktrees and isolated workspaces, and strong product taste. Active GitHub contributors preferred.

- You've shipped something with LLMs in production (agents, RAG, evals — not just wrappers)
- Comfortable owning a feature from idea to production without a lot of hand-holding
- Based in the US — SF Bay Area or LA strongly preferred
Why Cora:
- Work on cutting-edge applied AI: voice agents, knowledge graphs, multi-agent systems, evals, simulations, and more
- Real users, real impact, high autonomy
- Fast, fair interview loop — no BS
- Fully covered healthcare for you and your dependents
- 401(k) plan
- Flexible time off

Conductor lets builders run teams of coding agents. We're a small team, we recently announced our $22m Series A, and we're looking for exceptional software engineers and designers to join us.
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 recently announced our $42M Series B! 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.
