Cross‑team collaboration: partner with Product Engineering squads to enable faster and safer delivery of mobile features, guiding them in best practices for mobile architecture, performance optimisation, instrumentation, and observability. Drive performance improvements: lead efforts to reduce app startup time, optimise critical paths, migrate core systems, and remove legacy/native dependencies. Operational leadership: ensure the adoption and effective use of internal mobile tools such as monitoring (Prometheus, Honeycomb), error tracking (Sentry), and performance profiling. Stakeholder management: collaborate closely with leaders across engineering, product, and design to align priorities, balance trade‑offs, and remove road‑blocks. Must Have Proven experience managing mobile engineering teams or senior‑level technical leadership in mobile development. Strong technical background with Flutter and/or native mobile development (Android/iOS). Solid understanding of mobile software engineering principles, architectural patterns, and modularisation strategies. Experience with performance optimisation, dependency injection, and migration of core systems. Knowledge of mobile observability, monitoring, and debugging tools.
