For one of our clients, we are looking for an experienced Senior React Native Developer to join a strategic greenfield initiative focused on building a brand-new mobile application from the ground up using Expo.

Key Responsibilities
  • Design and develop a cross-platform mobile application using React Native and Expo.

  • Implement multi-screen navigation flows using React Navigation.

  • Translate the client’s design system into a scalable, reusable component library (tokens → primitives → complex components).

  • Build high-quality UI screens based on Figma designs and the newly created components.

  • Implement complex input forms with strong validation and smooth user experience.

  • Propose, justify, and implement the optimal technical stack and architectural approach.

  • Write and maintain automated tests using Jest and React Native Testing Library.

  • Integrate and manage push notifications, including permissions, routing, and background behavior.

  • Consume REST APIs using clean, maintainable data-access patterns.

  • Support deployment to the Apple App Store and Google Play Store (EAS or store workflows).

  • Implement monitoring, crash reporting, and performance tracking solutions.

  • Develop and integrate native modules where required.

  • Ensure long-term performance, maintainability, and scalability of the application.

Required Skills & Experience
  • Strong hands-on experience with React Native and Expo.

  • Advanced knowledge of TypeScript.

  • Proven expertise in React Navigation and multi-screen architectures.

  • Experience converting design systems into high-quality, scalable component libraries.

  • Strong testing experience with Jest and React Native Testing Library.

  • Hands-on experience with push notifications (Expo Notifications or custom native solutions).

  • Solid experience working with REST APIs, including authentication, error handling, and caching strategies.

  • Experience publishing mobile applications to both iOS and Android app stores.

  • Ability to write native code when required (Swift, Objective-C, Kotlin, Java).

  • Strong ability to work from Figma and deliver pixel-perfect UI components.

  • Excellent architectural skills with the ability to clearly justify technical decisions.

We offer a flexible collaboration model based on a B2B contract, with the opportunity to work on diverse projects
