You’ll also mentor other engineers and help the team maintain high technical standards.We value strong Kotlin or Java backend experience, paired with frontend skills in React and TypeScript. If you’re motivated by cross-cutting impact, enjoy working across service boundaries, and are excited by foundational engineering challenges, we’d love to hear from you.This role is primarily based in our Prague or Brno office with an office-centric hybrid schedule.Responsibilities
  • Take full ownership of features and platform capabilities, working across backend (Kotlin) and frontend (React/TypeScript) layers to deliver end-to-end solutions.
  • Lead the delivery of complex or ambiguous fullstack projects, breaking down problems, scoping technical work, and shipping iteratively.
  • Work primarily in Kotlin-based services to build reliable, scalable, and maintainable internal systems.
  • Contribute to platform-wide efforts like authentication, permissions, notifications, and shared UI patterns.
