Do you like creating and working on a product that is used by tens of thousands of people every day? Does being part of a small, ambitious, and fast-growing team energize you? Then you might be the perfect person to join our Product Team!

Did you know that 80% of the global workforce - 2.7B people - is deskless? Oneteam helps these ‘frontline workers’ feel more engaged and excited about their jobs!

Our web app is the heart of creating those better employee experiences. This is where companies organize their internal communication, create training courses, manage employees, and so much more.

As our new Back-end Developer, you will be responsible for building the ultimate app to help thousands of companies - like Fletcher Hotels, Albert Heijn, and Febo - create the best possible employee experience for millions of people.
