Build the future of AI agents

stagewise is building the open-source infrastructure layer for sovereign AI agents. We enable organizations to create, orchestrate, and operate AI agents across their entire business while maintaining full control over their models, data, and workflows.

Backed by Y Combinator, we're building the foundation for a future where AI agents become a core part of how companies build software, automate operations, and get work done.

What You'll Do

You'll work on the stagewise IDE, our open-source platform for managing coding agents in the age of agentic software development. Your mission is simple: build the go-to agentic IDE developers will reach for when working with AI.

You'll:

Ship features end-to-end across our React, TypeScript, and Node.js stack
Own GitHub issues from backlog to production
Review, improve, and approve agent-generated pull requests
Build stagewise with stagewise
Continuously benchmark competing products and identify where we should win
Improve performance, reliability, and developer experience
Create reusable UX patterns that scale across the product

If you enjoy eliminating unnecessary re-renders, squeezing out performance gains, refining interactions, and turning rough ideas into polished products, you'll probably enjoy this role.

Who We're Looking For

Strong TypeScript & React experience
Solid Node.js experience
Daily user of agentic coding tools
Comfortable taking ownership and driving projects independently
Understands what makes products feel great
Excellent English skills
Basic German skills

React and TypeScript expertise are not optional. You should be comfortable building and maintaining production-grade applications.

If your GitHub profile doesn't represent some of your proudest work, this role is probably not for you.

Bonus points if you:

Contribute to open source
Have built developer tools before
Have strong opinions about AI-assisted software development
Compare products and tools for fun

Why stagewise?

We believe the best people do their best work when they're trusted with real responsibility. You'll work directly with the founders, help shape our product roadmap, and have the freedom to pursue ideas you believe will move the company forward.

We're looking for people who are excited about what we're building and want to contribute to something very ambitious. If you want to help revolutionize the world with AI, you'll fit right in.

Also, the stagewise IDE is open source, and all of your contributions will be visible to the community.
