Full description
This is a remote position.
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.
