Senior Mobile Engineer (Flutter + Native)

About the Role

At Doodle, we are dedicated to solving time and unleashing people's growth. We are looking for a Senior Mobile Engineer with deep expertise in Flutter and strong proficiency in Android (iOS is nice-to-have). This role is critical for scaling our mobile platform, where you will be responsible for building high-quality, performant, and cross-platform features using Flutter, while leveraging your native expertise to bridge the gap and optimize specific platform functionalities.

You'll work closely with product and design teams to translate complex requirements into beautiful, fast, and reliable mobile experiences.

Key Responsibilities

• Cross-Platform Feature Development: Design, build, and maintain features across our mobile applications using Flutter and the Dart language, ensuring a consistent experience across iOS and Android.

• Native Integration & Optimization: Utilize your expertise in Android (Kotlin/Java) (and potentially iOS with Swift/Objective-C) to write native code for platform-specific modules, custom plugins, or performance-critical optimizations that cannot be achieved solely in Flutter.

• API Communication: Implement and manage efficient data communication with our backend services using GraphQL (and potentially REST), ensuring robust error handling and smooth data flow.

• Code Quality & Standards: Write clean, well-tested, and maintainable code; participate actively in code reviews, and help define and enforce best practices for mobile development (Flutter and native).

• Collaboration: Partner with Backend Engineers to define effective GraphQL schemas and with Product/Design to ensure technical feasibility and optimal user experience.

• Mentorship: Provide technical guidance and knowledge sharing to more junior engineers on Flutter development, architecture patterns, and native integration techniques.
  

Required Technical Qualifications

Experience: 5+ years of professional software engineering experience, with at least 3+ years focused on mobile application development and a track record of successfully launching and maintaining production apps.

Core Technology:

• Expert-level proficiency in Flutter and Dart.

• Strong proficiency in at least one native platform, preferably Android (Kotlin/Java), and optionally iOS (Swift/Objective-C).

• Data Communication: Deep, practical experience integrating mobile applications with backend services using GraphQL (e.g., Apollo, GraphQL-Flutter) and understanding its benefits and best practices.

• Architecture: Proven experience applying modern mobile architectural patterns (e.g., Provider, Bloc/Cubit, Riverpod, MVVM, Redux) to build scalable and maintainable Flutter applications.

• Tools & Testing: Experience with state management, dependency injection, mobile performance profiling, and implementing comprehensive unit and widget testing in Flutter.
