- Contributing to technical design discussions and leading multi-phase improvements, breaking work into incremental, testable deliveries aligned with team priorities
- Supporting continuous improvement initiatives that raise quality, reduce toil, and improve operational readiness within the domain
- Joining our on-call rota, sharing out of hours support duties as part of our incident response process
What We're Looking For:

- Strong TypeScript skills and a solid understanding of React patterns, architecture, and maintainable code practices at scale
- Practical experience profiling and improving performance in React Native applications (startup time, rendering, responsiveness, memory, etc.)
- Experience with React Native native modules / bridging; native Android (Kotlin/Java) and/or iOS (Swift) experience is a plus
- Familiarity with mobile development best practices, testing strategies, and CI/CD pipelines
