Job description

A well-funded YC-backed startup is building a next-gen development environment – an AI-powered IDE designed to reduce context-switching, automate repetitive workflows, and help engineers ship faster. They're looking for full-stack product engineers who are as much users as they are builders – engineers who understand what great developer experience looks like and want to shape it hands-on.

What you’ll do

1. Build product features that developers love (and actually use)
2. Use in-house LLMs to solve real workflow pain
3. Own the full stack – from backend logic to UI polish
4. Contribute to the evolution of a dev tool you’d be proud to use yourself

What you’ll need

1. 4+ years of experience in software engineering
2. Fluency with React, Next.js, and TypeScript, plus backend experience
3. You've built things other devs have used (or at least ranted about)
4. Solid understanding of Docker, CI/CD, and AWS or similar cloud infra
5. Bonus points for experience with LLMs or feature flag tooling

Why this team?

1. Competitive pay and meaningful equity
2. Small, fast-moving team with high ownership and zero corporate nonsense
3. Real AI products – not just decks and demos
