React Mobile Application Developer

Senior React Native Engineer The organisation is exploring how to deliver features more efficiently by combining native (Swift/Kotlin) applications with React Native and WebView-based journeys. If you thrive on de-risking emerging technologies and guiding architectural transitions, this role is ideal. We’re seeking a Senior React Native Engineer who can bridge native and hybrid technologies, run feasibility spikes, and provide guidance on where hybrid delivery is viable and where native implementation remains essential.

Lead technical investigations into the adoption of React Native for selected mobile journeys. Define integration strategies between React Native components and existing Swift and Kotlin codebases. Build proof-of-concept implementations to validate performance, reliability, and integration patterns.

Partner with iOS and Android technical architects to create aligned cross-platform delivery plans. Support experimentation with WebViews for configuration-driven or dynamic features. 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.
