- Jobs
A place where you build real things
No endless meetings or bureaucracy. Just writing good code, delivering great apps and enjoying your work.
Flexible working
We are flexible when it comes to working hours and location. We figure out together what works for you and the team.
Modern tech stack
We work with Flutter, NestJS and Angular. You get room to explore new frameworks and languages.
Varied projects
From a travel app to a reporting system for the KNVB. No two projects are the same.
Good salary
A salary that matches your experience, supplemented with a pension scheme and travel allowance.
Short lines, direct feedback and room for your own input. Your opinion actually matters.
Informal culture
Good coffee, great colleagues and an environment where you can be yourself.
Our tech stack
We primarily build with Flutter for mobile and Angular for web. Backends run on NestJS. You do not need to know everything already, but affinity with one or more of these technologies is a plus.
