Senior Mobile Engineer (React Native)

Senior React Native Engineer 

This role is an opportunity to define hybrid mobile strategy within a large-scale, native mobile ecosystem. 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.

The Impact You’ll Make

• 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.

• Quickly identify feasibility constraints and provide clear recommendations on hybrid vs. native choices.

• 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.

• Provide guidance on dependency management, packaging, and bridging techniques for hybrid components.

• Support experimentation with WebViews for configuration-driven or dynamic features.

• Mentor engineers as hybrid techniques are introduced into the organisation.

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.
