Mobile Lead Engineer

About the role

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.

What you’ll do

• 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.

What you’ll bring

• 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.
• Experience with both Flutter and React Native.
• White-label or multi-brand mobile delivery, including per-tenant build pipelines and separate store listings.
• Native iOS (Swift) or Android (Kotlin) development background.
• Push notification infrastructure (APNs, FCM) at scale.
• Mobile payments, wallets, or card tokenization (Apple Pay, Google Pay, or similar).
