Product Engineer (Working Student) (m/w/d)

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.
