• Architect, develop, and maintain reusable internal libraries and native modules.
• Collaborate with backend teams, QA, and design to deliver seamless, responsive mobile experiences.
• Maintain app stability during version transitions by identifying breaking changes and updating impacted code areas.
• Work in a monorepo environment, managing shared packages and internal tooling across multiple apps.
• Advocate for and implement performance and upgrade best practices across teams

• 5+ years of professional experience in mobile development, with extensive experience in React Native (4+ years).
• Deep understanding of:
• React hooks, state management patterns (e.g., Redux, Zustand).
• React Navigation, Reanimated, gesture handling and animation lifecycle.
• The JS/native bridge, async rendering, and threading implications.
• Strong TypeScript skills and a structured, modular coding approach.
• Hands-on experience maintaining and upgrading React Native apps, including handling deprecated APIs, breaking changes, and dependency conflicts.
• Proven experience integrating native SDKs and building custom native modules (Swift/Obj-C and Java/Kotlin).
• Familiarity with monorepo tools like Nx, TurboRepo, or Lerna.
• Proficient in using profiling tools (e.g. Flipper, Instruments, Hermes, Android Studio Profiler) to diagnose and fix app performance issues.
• Excellent communication, problem-solving, and technical documentation skills.

Nice to Have

• Experience in OTT/video app development or TV platforms (e.g. Android TV, tvOS).
• Contributions to open-source React Native libraries or performance tools.
• Familiarity with CI/CD tools and mobile deployment pipelines.
• Exposure to Hermes engine internals and React Native New Architecture (Fabric/TurboModules).
