Staff Mobile Engineer, Spend Foundation

As a Staff Mobile Engineer on the Mobile Foundations team, you will lead the technical direction of our mobile platform across iOS and Android. You will design and evolve the core architecture, own critical shared components, and act as a multiplier for mobile engineers across product teams.

You will:

Define and evolve mobile architecture Lead the design and evolution of the shared architecture for our native mobile apps, including navigation, state management, networking, offline strategies, and error handling. Drive modularisation and clear boundaries between foundation modules and product features.

Own core mobile platform capabilities Own and maintain shared libraries and frameworks (e.g. design system components, analytics, feature flags, experimentation, authentication, payments, observability). Be responsible for the application's authentication and authorization mechanisms. Ensure these components are stable, well-documented, and easy to adopt and extend by product teams.

Improve security, reliability, performance, and observability Drive mobile application security, including anti-tampering measures, certificate pinning, and security best practices. Define and track platform-level metrics such as crash-free sessions, ANRs, app start-up time, bundle size, and network performance. Partner with product teams to drive initiatives that improve reliability, performance, and overall mobile quality. Strengthen end-to-end observability across mobile (logging, metrics, tracing, crash reporting) and use data to guide priorities.
