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.

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.

• 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.

• 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
