Lead the technical direction of our mobile platform across iOS and Android.
Design and evolve the core architecture, own critical shared components, and act as a multiplier for mobile engineers across product teams.
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 and maintain shared libraries and frameworks (e.g. design system components, analytics, feature flags, experimentation, authentication, payments, observability).
Ensure these components are stable, well-documented, and easy to adopt and extend by product teams.
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.
Own and continuously improve our mobile CI/CD pipelines (e.g. GitHub Actions, Bitrise), reducing build times, flakiness, and friction in releasing features.
Improve developer experience for mobile engineers through tooling, templates, documentation, and automation.
Own the end‑to‑end mobile release process across iOS and Android, ensuring timely and reliable delivery of new versions.
Establish clear guidelines and lead the on‑call rotation for critical platform‑level incidents, ensuring rapid response and resolution.
Define, document, and enforce mobile engineering best practices across the organization to maintain a high bar for code quality and platform consistency.
Drive cross‑squad projects (e.g. rollout of a new design system, major architectural changes, cross‑platform feature foundations) from problem definition through to rollout and adoption.
Align stakeholders (EMs, PMs, designers, backend/platform teams) around technical direction and trade‑offs.
Lead by example with clean, testable, well‑structured code on either iOS or Android, while setting standards across both platforms.
Provide technical mentorship and guidance to senior and mid‑level engineers through design reviews, pairing, and coaching.
Contribute to and influence hiring, onboarding, and the growth of the mobile engineering community at Airwallex.
Requirements
8–10+ years of experience building native mobile applications on iOS or Android, including at least 3+ years operating at a Senior or Staff level.
Deep expertise in iOS: Swift, SwiftUI, Combine, async/await, or Android: Kotlin, AndroidX, Jetpack, Coroutines, Hilt with commercial knowledge of both platforms.
Proven track record leading cross‑team technical initiatives and evolving mobile architectures (e.g. modularisation, design systems, networking, offline support, or similar).
Strong focus on code quality and reliability:
Designs for testability and maintainability.
Writes high‑quality automated tests and uses coverage meaningfully.
Experience owning and improving mobile CI/CD pipelines (e.g. GitHub Actions, Bitrise), including build optimisation, test stability, and release workflows.
Demonstrated ability to influence without authority:
Aligns engineers, PMs, and designers around technical direction and makes pragmatic trade‑offs.
Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
