  • Collaborate closely with the Solution Architect, product managers, UI/UX designers, and other developers to deliver smooth, pixel-perfect user experiences.
  • Take full ownership of the development lifecycle, from technical design and implementation to testing, release, and post-launch maintenance.
  • Drive best practices for code quality, modular architecture, and component reusability within the React Native ecosystem.
  • Integrate mobile applications with backend APIs, and third-party SDKs and services.
  • Work with TypeScript, React Hooks, and state management tools to build scalable and maintainable codebases.
  • Lead efforts in mobile CI/CD pipelines, automated testing, and app distribution for Google Play Store and Apple App Store.
  • Debug and resolve complex technical issues across devices and operating systems, ensuring app performance and stability.
  • Provide technical leadership, mentoring, and guidance to junior and mid-level engineers.
  • Participate in Agile ceremonies: sprint planning, retrospectives, and daily stand-ups.
  • Collaborate on architectural decisions, contribute to documentation, and help define mobile development standards across the project.
  • Stay ahead of mobile and front-end trends, especially within the React Native and JavaScript/TypeScript ecosystem.

What you have:

  • 5+ years of professional experience in mobile application development, with at least 3 years in React Native.
  • Proven expertise with React Native architecture, TypeScript, and JavaScript.
  • Deep understanding of React component lifecycles, navigation patterns, and state management frameworks.
  • Experience with Vibe Coding methodology, React Native Reanimated, Expo, or React Native Vision Camera.
  • Demonstrated ability to deliver smooth, pixel-perfect interfaces and seamless animations across iOS and Android.
  • Experience taking end-to-end ownership of mobile app projects, from concept and architecture through development, testing, deployment, and iteration.
  • Experience integrating mobile apps with backend APIs, and authentication systems.
  • Familiarity with native modules and bridging for iOS (Swift/Objective-C) and Android (Kotlin/Java) when deeper system integrations are required.
  • Strong grasp of mobile UI/UX principles, responsive design, and accessibility standards.
  • Experience with CI/CD pipeline and version control.
  • Proven track record of thriving in fast-paced, product-centric teams, working closely with designers and product owners to bring ideas to life.
  • Solid understanding of software architecture patterns.

  • Thrived in a product-driven, fast-paced environment, adapting quickly to evolving requirements while maintaining a focus on quality and delivery.
