About the role
Build and ship the Windmill product end-to-end. The core challenge of building a developer platform: make it a delightful, intuitive experience while keeping the depth and power that developers expect.
For example, Windmill parses your code to extract dependencies in Python/TypeScript, generates a lockfile, and extracts parameters from function signatures to auto-generate a UI - letting developers focus on the code that matters while handling all the boilerplate, with escape hatches for manual control. All of that while being the fastest workflow engine on the market.
You'll work across the full stack, owning features from design to production:
- Frontend: build and refine the web IDE, flow editor, app builder, and dashboards in Svelte / TypeScript. Obsess over developer experience.
- Backend integration: wire frontend features to the Rust backend - APIs, real-time execution feedback, state management.
- Product sense: talk to users, read feedback, spot friction. Ship what matters, cut what doesn't.
- Full ownership: spec → design → implement → ship → iterate. Small team, no handoffs.
Example projects in your first 3 months
- Rebuild the flow editor's error handling UX - inline logs, step-level retry controls, visual diff between expected and actual output
- Ship a new component system for the app builder that lets users compose reusable, parameterized UI blocks
- Redesign the script editor's dependency management - auto-detect imports, inline version pinning, lockfile preview
- Build a real-time collaboration layer for the web IDE so multiple users can edit a workspace simultaneously
