Overview of the role:

We are looking for a talented React Native developer to join our team. The ideal candidate will work primarily on building and maintaining modern, scalable mobile applications using React Native, contributing to a smooth and performant user experience across both iOS and Android platforms. This role is perfect for someone passionate about clean, maintainable code, mobile UI/UX best practices, and continuous improvement. Familiarity with native modules, state management libraries (like Redux), and performance optimization for mobile apps is a strong advantage.

This role follows a hybrid approach to working, allowing you to combine working from home with working in our modern offices. These discussions are between you and your manager to find the best pattern for you both, while recognising that quality time together is essential for keeping us mission-aligned.

Our teams work from a lively location nestled within this historic city. Enjoy the best of both worlds with winter and summer offices, tantalizing free snacks and a gaming paradise for endless entertainment.

What you’ll do:

• Develop and maintain cross-platform mobile applications using React Native and modern JavaScript (ES6+) standards;

• Build scalable and maintainable mobile UI components, with a strong focus on performance and mobile UX best practices;

• Collaborate with designers, backend developers, product owners, and stakeholders to implement intuitive and user-friendly mobile solutions;

• Integrate mobile apps with RESTful APIs, and other third-party services;

• Write clean, reusable, and testable code following best practices in mobile development and architecture;

• Debug, troubleshoot, and optimize mobile app performance across devices and platforms;

• Contribute to documentation, including component usage, architectural decisions, and mobile-specific guidelines;

• Ensure device and OS compatibility, including various screen sizes, resolutions, and operating systems;

• Participate in peer code reviews and uphold high standards for code quality and consistency across the mobile team;

• Perform related duties as assigned.

What you’ll bring:

Skills, Capabilities & Experience Required:

• 2–4 years of professional experience in mobile development, with hands-on experience building applications using React Native and TypeScript

• Solid working knowledge of React Native and its ecosystem, including Hooks, Context API, navigation, and common state management solutions (e.g., Redux, Zustand, or similar)

• Experience contributing to and shipping production-ready mobile applications, with an emphasis on code quality, maintainability, and scalability

•  Good understanding of mobile UI/UX principles, accessibility basics, performance considerations, and platform-specific design patterns (iOS and Android)

•  Practical experience integrating mobile applications with RESTful APIs

• Confidence in implementing responsive layouts and styling for mobile apps

• Experience working with Git and collaborating in team-based, Git-driven workflows (e.g., GitHub or GitLab)

• Exposure to unit and/or integration testing for mobile applications (e.g., Jest, React Native Testing Library); deeper testing experience is a plus

• Familiarity with CI/CD pipelines, mobile build processes, deployment automation, or over-the-air updates is a plus

• Some exposure to WebView usage or native modules is a plus, with willingness to learn more about platform-specific code when needed

• Awareness of cloud services and mobile deployment processes (e.g., Firebase, App Store, Google Play) is a plus

• Comfortable communicating in written and spoken English within a cross-functional team
