About the role

  • Making architectural decisions around observability, testing, and security best practices

Qualifications

  • 3-5+ years shipping production backend services, with deep expertise in Go
  • Strong API design — REST/RPC, contracts, versioning
  • Solid with PostgreSQL: schema design, query optimization, migrations
  • Backend fundamentals: authentication/authorization, server-side performance, real-time data flows (WebSockets, SSE)
  • Working TypeScript (Next.js is a plus) competence — ability to wire features end-to-end in the frontend if needed
  • Understand data fetching patterns on frontend side
  • Excited to work in person from Prague on a devtool product
  • Ownership mentality: end-to-end project ownership
  • Comfortable talking to customers and explaining technical tradeoffs
