Technical Lead React Native

This role offers the opportunity to define and lead hybrid mobile delivery within a high-scale mobile engineering organisation serving millions of users. As the organisation continues to evolve its native iOS and Android applications, React Native and WebView-based journeys are being explored to accelerate delivery, improve reuse, and unlock configuration-driven experiences.

We’re seeking an experienced React Native Engineering Lead with strong architectural judgement and hands-on capability. You will own the hybrid mobile strategy across platforms, working closely with iOS and Android Technical Architects to evaluate feasibility, define guardrails, and establish scalable patterns for hybrid delivery within a complex native ecosystem.

You will operate as a senior technical leader — embedded with engineering teams, guiding architectural decisions, running technical spikes, and ensuring hybrid approaches are introduced safely, pragmatically, and at scale.

The Impact You’ll Make

• Own the technical direction and strategy for React Native and hybrid delivery across iOS and Android platforms.
• Define when hybrid approaches are appropriate and where native implementation remains essential.
• Lead feasibility assessments and proof-of-concepts to validate performance, stability, security, and developer experience.
• Design and govern integration patterns between React Native and existing Swift and Kotlin codebases.
• Establish standards for dependency management, packaging, versioning, and native module bridging.
• Collaborate closely with iOS and Android Technical Architects to align on cross-platform architectural decisions.
• Support experimentation with WebView-based and configuration-driven mobile experiences.
• Identify and resolve architectural constraints that impact release velocity, maintainability, or reliability.
• Provide technical leadership across multiple teams adopting hybrid approaches.
• Mentor engineers and uplift hybrid engineering capability across the organisation.

Technology Stack & Requirements

• Strong, hands-on experience delivering production React Native applications at scale .
• Excellent knowledge of JavaScript / TypeScript and modern React architecture.
• Working knowledge of Swift and Kotlin , sufficient to design, review, and guide native integrations.
• Proven experience embedding React Native within large, existing native mobile applications .
• Deep understanding of mobile performance, lifecycle management, and platform constraints.
• Experience operating within complex, multi-team mobile environments.

Bonus Points

• Experience scaling hybrid delivery across large engineering organisations.
• Deep familiarity with native module bridging on both iOS and Android.
• Experience designing governance models for shared hybrid components.
• Experience with WebView-based mobile architectures.
• Background in high-scale consumer or transactional mobile applications.

Location

• Based in London (Farringdon)
• Hybrid: 2-3 days in the office
