Technology Stack & Requirements ● Strong professional experience with React Native, including integration with native modules. ● Proficiency in JavaScript / TypeScript. ● Working knowledge of Swift and Kotlin to support integration within existing native architectures. ● Experience delivering hybrid mobile features in environments with large native applications. ● Understanding of cross-platform performance considerations, constraints, and architectural patterns. Bonus Points ● Experience scaling hybrid solutions across large engineering organisations. ● Deep familiarity with native module bridging for both iOS and Android. ● Experience with WebView-based solutions in mobile contexts. ● Exposure to complex enterprise mobile environments with multi-team ownership. What You’ll Bring to Us ● Ability to evaluate feasibility rapidly and articulate architectural trade-offs. ● Practical experience guiding teams through hybrid adoption. ● Strong cross-platform communication skills. ● Balanced, pragmatic thinking combining stability, performance, and delivery considerations. ● Curiosity and a methodical, experimental approach to new technology adoption.
