Our client is seeking a Senior Mobile Engineer with deep experience in Flutter and strong native Android skills (iOS experience is a plus). In this role, you’ll play a key part in scaling our mobile platform—building high-performance, cross-platform features while using your native engineering expertise to optimise platform-specific capabilities.

Key Responsibilities

• Design, build, and maintain mobile features using Flutter and Dart, ensuring a consistent and seamless user experience.
• Apply your Android (Kotlin/Java) expertise—and optionally iOS (Swift/Objective-C)—to write native modules, develop custom plugins, and optimise performance.
• Implement efficient data communication with backend services using GraphQL (and optionally REST), focusing on reliability, performance, and robust error handling.
• Write clean, maintainable, well-tested code. Participate in code reviews and contribute to defining and reinforcing best practices in both Flutter and native mobile development.
• Work with Backend Engineers to shape effective GraphQL schemas and partner with Product and Design teams to ensure technical feasibility and an exceptional user experience.
• Support and mentor junior engineers by sharing knowledge on Flutter development, architectural patterns, and native integrations.

• Required Technical Qualifications
• 5+ years of professional software engineering experience, including at least 3+ years in mobile development with a history of shipping and maintaining production apps.
• Expert-level proficiency in Flutter and Dart
• Strong proficiency in a native mobile platform, preferably Android (Kotlin/Java), with bonus points for iOS experience (Swift/Objective-C)
• Significant hands-on experience integrating mobile apps with backend services via GraphQL (e.g., Apollo, GraphQL-Flutter), with a strong understanding of best practices.
• Experience applying modern mobile architecture patterns—such as Provider, Bloc/Cubit, Riverpod, MVVM, or Redux—to build scalable, maintainable apps.
• Proficiency with state management, dependency injection, performance profiling, and writing comprehensive unit and widget tests in Flutter.
