  • Partner with Product and Design to translate requirements into shipped solutions

What they're looking for

  • SDK and library design with clean, intuitive APIs
  • React and TypeScript (2–3 years professional experience)
  • AI/LLM integration and custom automation workflows (Claude, etc.)
  • Library packaging and distribution (tsup, Rollup, Vite, npm, ESM/CJS)

  • Technical writing and developer documentation
  • Code review and standard engineering workflows

Benefits
