Code. Build. Innovate. 

You have built and published multiple React Native apps using Expo. You focus on achieving the best user experience and are searching for a team that’s as forward-thinking  as you are. Sounds good? Then you’re in the right place place.

Your role 

As a React Native Developer, you will assist in building and maintaining mobile platforms for leading clients such as Rituals, KNVB, and VodafoneZiggo. You’ll be part of a small team of React Native developers who collaborate with native (iOS/Android) developers to uphold a high standard of app development while maintaining a focus on the end product.

You play a key role in developing and maintaining mobile applications while actively contributing to new features and improvements. You enjoy working with the latest and well-established technologies such as Expo, Fastlane, and Cursor/CoPilot Agent.

• Build and optimize React Native apps using Expo. 

  • Focus on building applications that have the native feel for end-users. 

  • Exploring new ways of working and bringing them to the team. 

  • Filling in the gaps in technology by writing your own native modules/plugins

• Maintain a high standard of code quality and making sure to continuously deliver:

  • Writing Typescript with strong type safety and clear typings. 

  • Use Jest and other testing solutions to roll out with confidence. 

  • Setting up and improving CI/CD based on the project’s needs. 

• Creating a feedback cycle that focuses on getting to the desired product:

  • Distribute applications to the client, testers and end-users. 

  • Add monitoring and analytics to get feedback on app usage. 

  • Translate feedback after each release to new work items and improve the product. 

• Finding your way to deliver value to your team and clients. 

  • Mentor Junior developers and interns. 

  • Actively speak your mind and listen to input. 

  • Be open about your expertise and limitations to find the sweet spot for collaboration. 

• Experience: At least 3 years as a React Native Developer with a strong focus on mobile applications. 

• Skills: You know Expo, Expo Router, TypeScript, and React inside out. 

• Extras: Experience with native modules, other platforms like TV, Watches and web, are a plus. 

• Language: Fluent in English. Dutch is a bonus. 

• Mindset: You’re a team player and an innovator who is always looking for new solutions.
