Y Combinator created a new model for funding early stage startups. Four times a year we invest in a large number of startups. Backed by Y Combinator.
About the role
Y Combinator is building a new generation of products for the AI-native era — and we're hiring product engineers to build them. Some ship in the open to hundreds of thousands of developers (gstack, gbrain — already north of 130,000 GitHub stars between them). Some are proprietary products in their own right (Paxel). All of them start from the same belief: a single builder with the right tooling now ships like a team of twenty, and we intend to build the tools — and the platforms — that prove it.
What they're looking for
- Nice to have - LLMs, prompt engineering, or agent-based systems - Open-source maintainership and community engagement - TypeScript, Postgres/pgvector, Rails, React (the stack our current products run on) - Retrieval, search, or knowledge-graph systems
- We care more about your ability to build and ship complete products than any specific stack

This is a rare seat. You won't be maintaining someone else's roadmap. You'll be taking new products from zero to one, owning them end-to-end, and putting them in front of real users fast.
Take new products from 0→1 — design, build, and ship full-stack systems and developer tools end-to-end
Build AI-native software: agent orchestration, semantic search, embeddings, knowledge graphs, LLM workflows
Own developer and user experience completely — 30-second installs, time-to-first-value measured in minutes, interfaces people actually want to use
Ship some work in the open and engage a real community; ship other work as commercial product. Pick the right call for each
Use your own fully...
