Full-Stack Product Engineer
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 understands what great developer experience looks like and wants to shape it hands-on.
What you’ll do
-
Build product features that developers love (and actually use)
-
Use in-house LLMs to solve real workflow pain
-
Own the full stack – from backend logic to UI polish
-
Contribute to the evolution of a dev tool you’d be proud to use yourself
What you’ll need
-
4+ years of experience in software engineering
-
Fluency with React, Next.js, and TypeScript, plus backend experience
-
You've built things other devs have used (or at least ranted about)
-
Solid understanding of Docker, CI/CD, and AWS or similar cloud infra
-
Bonus points for experience with LLMs or feature flag tooling
Why this team?
-
Competitive pay and meaningful equity
-
Hybrid model (3 days in-office, central London)
-
Small, fast-moving team with high ownership and zero corporate nonsense
-
Real AI products – not just decks and demos
