  • Build scalable, reusable, and maintainable components following modern mobile engineering best practices.
  • Take ownership of complex technical problems across the React Native application stack.
  • Evaluate and adopt appropriate libraries, frameworks, and architectural patterns as the mobile platform evolves.
  • Contribute to internal libraries and platform capabilities where existing solutions do not adequately address engineering requirements.
  • Drive mobile performance improvements across rendering, startup time, memory usage, responsiveness, and application stability.
  • Identify and eliminate unnecessary re-renders and inefficient render cycles.
  • Optimize large lists and complex UI interactions to deliver smooth experiences across a wide range of devices.
  • Analyze application performance and proactively identify bottlenecks before they impact customers.
  • Establish and promote performance engineering best practices across the mobile team.
  • Work deeply with React Native internals and modern React Native architecture.
  • Build and optimize solutions using technologies such as FlashList, React Native Reanimated, React Native Gesture Handler, and Expo.
  • Investigate complex framework and platform-level issues across iOS and Android.
  • Work with TurboModules and native platform capabilities when React Native abstractions are insufficient.

  • Develop and maintain comprehensive test cases to ensure application quality and reliability.
  • Debug complex production and development issues across the mobile stack.
  • Establish practices that improve application stability, performance, and release quality.
  • Participate in code reviews and provide thoughtful feedback on architecture, implementation, performance, and maintainability.
  • Partner with Product, Design, Backend, and other engineering teams to define and implement scalable mobile solutions.
  • Translate product and customer requirements into robust technical designs and implementation plans.
  • Collaborate across teams to identify technical dependencies, trade-offs, and opportunities for improving the overall customer experience.
  • Communicate technical decisions and complex mobile engineering concepts clearly to both technical and non-technical stakeholders.
  • Mentor junior and mid-level engineers and help raise the technical bar across the mobile team.
  • Promote clean coding practices, performance optimization, testing, and engineering excellence.
  • Contribute to technical discussions, architecture decisions, and long-term mobile engineering strategy.
  • Stay current with developments in React Native, mobile platforms, and modern application performance techniques.

Qualifications
