Mobile Lead Developer (Flutter)

OUR OPPORTUNITY We are looking for a Mobile Lead Engineer to drive the development of modern, scalable, and user-centric cross-platform mobile applications for iOS and Android. This role combines strong hands-on development expertise with leadership responsibilities, guiding mobile engineers and ensuring high-quality, performant, and secure applications from a single shared codebase. The ideal candidate is passionate about clean architecture, design systems, and delivering seamless mobile experiences in complex, data-driven environments. YOU WILL » Lead the design, development, and delivery of cross-platform mobile applications for iOS and Android. » Define and enforce mobile architecture, state management patterns, coding standards, and best practices. » Mentor, coach, and manage mobile engineers, supporting their growth and performance. » Collaborate closely with UX/UI, Product, Backend, and QA teams to deliver high-quality solutions. » Drive the adoption and evolution of a shared component library and consistent design language across both platforms. » Own runtime theming and configuration, so branding and enabled features can be configured rather than forked per build. » Ensure applications meet accessibility standards on both platforms. » Own mobile security posture — secure storage, certificate pinning, biometric authentication, root/jailbreak detection, and safe token handling. » Integrate mobile applications with backend REST APIs and OAuth2 / OpenID Connect authentication flows. » Optimize application performance, startup time, rendering, battery and network efficiency. » Own the release process end to end: build pipelines, code signing, App Store and Google Play submission, phased rollout and crash monitoring. » Oversee code reviews, technical decisions, and quality assurance processes. » Stay up to date with the latest mobile technologies, framework releases, and industry trends. Requirements » TO BE SUCCESSFUL IN THE ROLE YOU NEED » Bachelor's degree in Computer Science, Engineering, or a related field. » 7–10 years of experience in mobile development, with at least 2–3 years in a lead role. » Strong proficiency in Flutter and Dart, or in React Native and TypeScript, with a willingness to work in either. » Proven experience shipping and maintaining production cross-platform applications on both 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 manage Xcode and Gradle build configuration. » Strong understanding of mobile architecture patterns and state management (Bloc, Riverpod, Provider, Redux, or equivalents) in a modular app structure. » Solid grasp of mobile security best practices and secure handling of sensitive data on device. » Experience with RESTful API integration, offline handling, and background synchronization. » Experience with mobile CI/CD (Fastlane, GitLab CI, or similar) and automated build and signing. » Familiarity with mobile testing (widget/component tests, integration tests, and device-farm or emulator-based E2E). » Experience with version control systems (Git) and Agile/Scrum environments. » Excellent leadership, communication, and problem-solving skills.
