What you’ll do

• 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

What you need to have

• 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

• 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
