Sobre este puesto de Senior App Developer en Basic-Fit
Do you get excited about building software that scales to millions of users? Are you the kind of engineer who doesn't just fix problems — but reshapes the way a team works? And does the idea of your code directly impacting the fitness experience of 4.7 million members across Europe sound like your kind of challenge? Then keep reading.
At Basic-Fit, technology isn't a support function — it's how we grow. Our clubs run 24/7 thanks to the software and hardware we build in-house, and our members manage everything from freezing their membership to tracking their workouts through our app. That means what you build truly matters — at scale, across 6 countries, every single day.
Your Role
As a Senior App Developer, you're not just shipping features off a roadmap. You're a pivotal engineer who shapes how the team works, raises the bar on quality, and helps define our long-term engineering direction. You'll be working in Tilburg alongside a talented mix of React (Native) developers, Node.js developers, Product Owners, Designers - and even a Talent Coach dedicated to your personal growth.
Your tasks:
Working closely with Product and Design to build high-quality mobile experiences
Taking ownership of the mobile application architecture and keeping the app scalable and maintainable
Constantly improving the release process and ensuring stable iOS and Android releases
Monitoring and improving app performance, stability, and crash rates
Keeping up with the React Native/mobile ecosystem and constantly evaluating recent trends while scoping them to Basic-Fit context.
Mentoring other developers and sharing (mobile) best practices
Your tech stack:
We build our applications with React Native, TypeScript, Tailwind, Storybook, Service Workers, Next.js and Playwright. Our APIs run on Nest.js, TypeScript, Prisma, Postgres, Redis, Azure EventGrid and Azure ServiceBus. To keep everything running, we use Heroku, Azure DevOps, New Relic, Akamai and GitHub Copilot.
Who are you?
You're a problem solver at heart, with software as your weapon of choice. You understand that making real impact requires collaboration — you're not afraid to knock on doors to get things done. Scale and complexity don't intimidate you; they motivate you.
Additionally, we're looking for someone who:
Has demonstrated experience with at least part of our tech stack and loves sharing that knowledge
Understands how to manage risk and isn't shy about taking ownership
Thrives in a fast-moving environment where unnecessary rituals are kept to a minimum
Is eager to explore AI tooling in the development process
Is eligible to work in the Netherlands (we don't sponsor new work visas, but existing sponsorships can be transferred)
