About the role

  • Deep expertise in mobile architecture (Flutter/Dart, native bridges, modularization, monorepos), designing end-to-end solutions for app startup, navigation, state management, and release lifecycle.
  • Advanced knowledge of BDC (Backend Driven Content) as the primary server-driven UI platform, defining integrations with Flutter and NuDS for fast, safe iterations without dependence on store releases.
  • Ability to define technical vision for Mobile Platforms areas (App Foundations, App Enablement, App Release), aligning architectural choices with corporate goals such as App Excellence and Magic App.
  • Strong track record leading ambiguous, large-scale cross-organizational initiatives, such as native-to-Flutter/BDC migrations, startup refactors, performance optimizations, and observability redesigns.
  • Experience in platform engineering: defining canonical patterns, RFCs, reference implementations, tools and reusable libraries for easy adoption by internal teams.
  • Passion for observability, reliability and mobile release health: integrating metrics (startup, TTFD, crashes, jank), CI/CD, rollouts and on-call practices.
  • Motivated by high-impact horizontal platforms, shaping in-app experiences across multiple markets.

Requirements

  • Experience with test automation (unit, integration, end-to-end) and implementing continuous quality processes.
  • Familiarity with error and metrics monitoring tools (Crashlytics or DataDog).
  • Ability to develop robust, scalable applications, prioritizing quality, performance and user experience.
  • Proficiency with BloC (flutter_bloc, bloc_test) applied in real projects.
  • Experience with Clean Architecture.
  • Published production apps on Google Play and the App Store.
  • Experience with REST/GraphQL APIs and secure authentication (OAuth 2.0, JWT, biometric).
