Mobile Developer

Role: Engineering Lead, Frontend (Mobile Platforms)

Location: Miami FL — Onsite

Duration: Contract

Job Summary:

We are seeking an experienced Frontend Engineering Manager to lead our mobile application development team across Android and iOS. The ideal candidate has strong hands-on background in native mobile development and has successfully led or participated in a React Native brownfield migration. This role blends technical leadership, people management, and architectural decision-making to modernize our mobile platform while ensuring continuity of existing functionality and user experience.

Key Responsibilities

• Lead, mentor, and grow a team of frontend/mobile engineers working across Android, iOS, and React Native.
• Own the technical strategy and roadmap for migrating legacy native mobile applications (Android/Kotlin/Java, iOS/Swift/Objective-C) into a unified React Native codebase using a brownfield migration approach.
• Define and enforce best practices for incremental migration, ensuring minimal disruption to existing app functionality, performance, and release cadence.
• Partner with product managers, designers, and backend engineering teams to align technical execution with business and UX goals.
• Establish CI/CD pipelines, testing strategies, and code quality standards suited to a hybrid native/React Native codebase.
• Drive decisions on native module bridging, third-party library evaluation, and platform-specific edge cases during migration.
• Manage sprint planning, technical estimation, and delivery timelines for mobile initiatives.
• Conduct code reviews and provide technical guidance on architecture, performance optimization, and app stability.
• Oversee the native-to-React Native integration boundary (navigation bridging, Turbo Modules/JSI, lifecycle handoff) owned by the iOS and React Native leads, ensuring consistent architecture across platforms.
• Own production monitoring, crash analytics, and performance metrics (App Store/Play Store ratings, crash-free rates, load times).
• Support hiring, onboarding, and career development of mobile engineers.
• Stay current with Android/iOS platform updates, React Native releases, and mobile ecosystem trends; assess their impact on the roadmap.

Required Qualifications

• 8+ years of experience in mobile/frontend software development, with 2+ years in a people management or technical leadership role.
• Strong working knowledge of native Android development (Kotlin/Java) and native iOS development (Swift/Objective-C).
• Demonstrated experience leading or executing a brownfield migration — integrating React Native into an existing native mobile application (not a greenfield/new-app build).
• Solid understanding of React Native architecture, native module bridging, and hybrid app performance considerations.
• Familiarity with native module/bridge and Turbo Module/JSI patterns used to expose native iOS and Android capabilities to React Native.
• Experience with mobile CI/CD tools (Fastlane, Bitrise, GitHub Actions, Jenkins, etc.).
• Familiarity with app store release processes (Apple App Store, Google Play Console), including versioning, phased rollouts, and compliance requirements.
• Strong understanding of mobile app architecture patterns (MVVM, MVI, MVP, MVC, MV, Clean Architecture) and state management (Redux, MobX, Context API, etc.).
• Experience with performance profiling, crash reporting, and monitoring tools (Firebase Crashlytics, Sentry, New Relic).
• Excellent communication skills with the ability to work cross-functionally with product, design, QA, and backend teams.
