Requirements
  • At least 4 years of professional experience in frontend or mobile engineering, with a meaningful portion spent on platform, infrastructure, or developer tooling work
  • Production-grade TypeScript - strong typing discipline, not just familiarity
  • Hands-on React Native experience in a production app, including an understanding of the native layer
  • Practical Kotlin experience on Android - native modules, build configuration, or Android-side CI/CD work
  • Direct involvement in CI/CD pipeline ownership or significant contribution — mobile or frontend, any tooling
  • Ability to think in systems and write code for other engineers, not just end users
  • Comfortable working autonomously and making decisions without waiting for full consensus
Responsibilities
  • Own and evolve our monorepo, ensuring it stays healthy, performant, and easy to work in as the codebase grows
  • Design, build, and maintain CI/CD pipelines for React Native and web targets, driving reliability and fast feedback loops for the engineering team
  • Author and maintain shared TypeScript libraries — state management patterns, networking layers, error handling utilities — consumed across all frontend products
  • Own the mobile release process end-to-end, including Android build configuration, versioning, and deployment automation
  • Integrate and maintain observability tooling (Sentry, Amplitude) at the platform level, so product teams get reliable instrumentation out of the box
  • Identify and resolve build bottlenecks, dependency issues, and tooling gaps that slow down engineering velocity
  • Collaborate closely with product frontend teams to understand their pain points and translate them into platform improvements
Desired Qualifications
  • Hands-on experience with nx or pnpm workspaces specifically
  • Familiarity with Vite and Expo for tooling or build configuration
  • Exposure to Reanimated or React Native Gesture Handler
  • Background in fintech or a high-scale consumer app where release reliability was business-critical
