You'll work across our entire product stack — from the AI pipeline to the customer-facing widget and dashboard. We ship fast and value engineers who bring opinions to the table.


What you'll do

  • Build and maintain product features end-to-end across Next.js, Convex, and our AI agent layer
  • Own the developer experience of our embed/widget SDK
  • Collaborate with the founding team to shape product direction
  • Review PRs and raise the bar for code quality across the codebase

What we're looking for

  • 5+ years of production experience with TypeScript and React
  • Strong familiarity with server-side rendering and API design
  • Experience shipping and maintaining complex SaaS products
  • Comfortable working in a fast-moving, ambiguous early-stage environment

Nice to have

  • Prior work on AI/LLM product integration
  • Experience building developer tools or SDKs
