• Drive performance improvements: bundles, memory, startup, animations, offline.

• Participate in PR reviews and pair programming.

• Contribute to AI features (chatbots, scraping, retrieval systems).

• Manage store releases, updates, and monitoring.

• 2-3+ years' commercial React Native experience.

• Strong skills in TypeScript, navigation, and state management (Redux, Zustand, or React Query).

• Experience with performance profiling and optimisation in React Native

• Comfortable integrating REST and GraphQL APIs.

• Exposure to CI/CD, app store releases, and OTA updates (e.g. CodePush).

• Nice-to-haves: Native modules (Swift/Kotlin), app security, crash/analytics tools, or experience with chatbots/RAG systems.

• Salary guide £60,000; up to £70,000 for candidates close to senior level.

• Hybrid in Holborn: around three days a week in the office initially, with more flexibility once established.

• Small, agile team working with modern tooling and quick feedback loops.
