Enjoy benefits such as high-impact projects, modern tech, and a dynamic, creator-led environment.
The ideal candidate has extensive experience delivering large-scale apps using React Native, JavaScript/TypeScript, and libraries such as Reanimated, Skia, Apollo Client, Expo, and React Navigation. Strong skills in mobile architecture, state management, app store deployment, automated testing, CI/CD, and cloud platforms (AWS, GCP, Azure) are essential. Excellent communication, a self-driven mindset, and excitement for AI-assisted development are critical to success in this collaborative and fast-paced team.
We are Affinity Labs, a UK-based venture studio building AI-powered, creator-led software brands for the creator economy. We partner with leading creators to transform their influence into scalable technology companies, having shipped 4 mobile applications in 4 months across education, wellness and productivity.
This is a rare opportunity to join a fast-moving studio at the ground floor and take ownership of mobile development across our growing portfolio of products. You'll work directly with our founding team to build, ship and scale React Native applications that reach engaged communities of hundreds of thousands of users.
You'll be hands-on across the full product lifecycle - from rapid MVP builds through to production-grade releases - while helping establish the mobile engineering foundations for a multi-product studio.
