We are seeking a Senior/Lead React Native Engineer to take ownership of mobile application architecture, framework, and overall quality. This role goes beyond coding—it requires establishing best practices, improving architecture, and ensuring delivery of a high-quality, production-grade application across both iOS and Android.

Key Responsibilities

  • Architecture & Framework
    • Define and implement scalable architecture patterns for React Native.
    • Establish strategies for over-the-air (OTA) updates to streamline app delivery.
  • Code Quality & Testing
    • Set up and maintain a unit testing framework (e.g., Jest, Detox, RN Testing Library).
    • Enforce linting, static analysis, and code review processes to raise overall code quality.
  • CI/CD & Deployment
    • Implement CI/CD pipelines for automated builds, testing, and deployments.
    • Optimize release workflows to deliver fast and reliable builds for iOS and Android.
  • Analytics & Event Tracking
    • Verify that event funnels and user interactions are captured correctly.
    • Collaborate with product and analytics teams to ensure accurate data collection.
  • Performance Optimization
    • Improve application performance, including rendering, load times, and memory usage.
    • Apply build optimizations for scalable, production-grade delivery.
  • Leadership & Mentorship
    • Provide technical leadership to the mobile team.
    • Introduce best practices and guide the team in building sustainable solutions.

Skills, Knowledge and Expertise

Requirements
  • 5+ years of professional experience in React Native building production-grade apps.
  • Strong expertise in Xcode, Android Studio, native build tools, and deployment workflows.
  • Hands-on experience with CI/CD pipelines (e.g., GitHub Actions, Fastlane, Bitrise, CircleCI).
  • Solid knowledge of testing frameworks (Jest, Detox, RN Testing Library).
  • Proven ability to design scalable architecture and improve code quality.
  • Strong understanding of analytics and event tracking tools — including Google Events, Meta Events, and Sentry (for app analytics).
  • Familiarity with OTA update solutions for React Native.
  • Experience with TypeScript in React Native projects.
  • Strong understanding of analytics and event tracking tools.
  • Excellent debugging, problem-solving, and performance optimization skills.
  • Ability to lead, mentor, and collaborate effectively.
Nice to Have
  • Knowledge of mobile app security, offline-first approaches, and data synchronization.
  • Familiarity with App Store and Play Store release processes.
  • Background in scaling apps with large user bases.
