Lead React Native Engineer
The RoleWe are looking for a Lead React Native Engineer to join a well funded health technology company building mobile products that power clinically meaningful diagnostic experiences.
This is a hands on senior individual contributor role with React Native at the core of the platform. You will take ownership of the mobile architecture across iOS and Android, working on core application foundations, performance critical features, and scalable mobile systems used in real world healthcare settings.
This is not a feature factory role. You will have genuine architectural input, clear ownership over what you build, and influence over how the mobile platform evolves as the company scales internationally.
- Own and evolve the React Native mobile platform across iOS and Android
- Design and implement scalable mobile architecture using React Native and TypeScript
- Work closely with product, design, and backend teams to deliver high quality mobile experiences
- Define performance standards and improve reliability across the mobile stack
- Architect and maintain state management and application structure at scale
- Integrate native modules using Swift or Kotlin where required
- Work with device capabilities including camera and other hardware integrations
- Improve release processes, testing strategy, and engineering discipline
- Contribute to CI and CD pipelines and mobile deployment workflows
- Lead architectural discussions and set technical direction for mobile engineering
- Strong production experience with React Native and TypeScript
- Experience using Expo in live production environments
- Deep understanding of React hooks, performance optimisation, and state management patterns
- Experience architecting and scaling complex mobile applications
- High standards for performance, testing, reliability, and release quality
- Ability to communicate architectural trade offs clearly
- Strong ownership mindset and ability to operate autonomously in a senior individual contributor capacity
- Experience with modern React Native architecture including Fabric, JSI, and TurboModules
- Native module integration experience with Swift or Kotlin
- Experience working with camera APIs or device level integrations
- Experience with mobile CI and CD tools such as Fastlane, GitHub Actions, or Bitrise
- Exposure to crash monitoring and observability tooling such as Sentry or Firebase
- Experience scaling mobile products across international markets
- Remote first within the UK with occasional travel for key sessions and events
- £80,000 to £90,000 base salary
- Equity options included
If you are excited by owning a mobile platform that delivers meaningful healthcare impact, shaping architecture from the ground up, and raising engineering standards in a scaling environment, we would love to hear from you.
