Senior Mobile Developer (Flutter) at CoorB

Job description

OUR OPPORTUNITY We are looking for a Senior Mobile Engineer to build modern, scalable, and user-centric cross-platform mobile applications for iOS and Android. This role is hands-on and technically deep, with ownership of significant parts of the mobile application from design through to release. The ideal candidate is passionate about clean architecture, design systems, and delivering seamless mobile experiences in complex, data-driven environments — and takes pride in raising the standard of the codebase and the engineers around them. YOU WILL » Design, develop, and deliver features for cross-platform mobile applications, owning them end to end. » Contribute to mobile architecture, state management patterns and coding standards, and apply them consistently. » Build and evolve a shared component library and consistent design language across both platforms. » Implement runtime theming and configuration, so branding and enabled features are configured rather than hard-coded. » Ensure features are accessible and behave correctly across a range of devices and screen sizes. » Write platform-specific native code where the framework's plugin ecosystem falls short. » Apply mobile security best practices — secure storage, biometric authentication, and safe token handling. » Integrate with backend REST APIs and OAuth2 / OpenID Connect authentication flows, handling offline and error states properly. » Optimize application performance, startup time, rendering, and network efficiency. » Write and maintain automated tests (unit, widget/component, and integration). » Review your colleagues' code, mentor less experienced engineers, and raise the quality bar of the team. » Write clear technical documentation and design notes on Confluence. » Participate in daily, weekly and monthly team ceremonies and planning. Requirements » TO BE SUCCESSFUL IN THE ROLE YOU NEED » Bachelor's degree in Computer Science, Engineering, or a related field. » 5+ years of hands-on mobile development experience. » Strong proficiency in Flutter and Dart, or in React Native and TypeScript, with a willingness to work in either. » Proven experience shipping production cross-platform applications to the App Store and Google Play. » Working knowledge of the underlying native platforms — enough to write platform channels or native modules, debug platform-specific issues, and work with Xcode and Gradle build configuration. » Strong understanding of mobile architecture patterns and state management (Bloc, Riverpod, Provider, Redux, or equivalents). » Solid grasp of mobile security fundamentals and secure handling of sensitive data on device. » Experience with RESTful API integration, offline handling, and background synchronization. » Experience with automated mobile testing. » Comfortable with Git, code review workflows and Agile delivery. » Good verbal and written English communication skills.
