Back-End Developer- werkstudent


TAPP ( is an app that allows people to have an even better time in bars and cafés. This is our core. But at the same time, TAPP is more, much more. Using our unique knowledge of the hospitality industry, we create valuable insights and analytics for the entire hospitality supply chain. And in addition, our solutions can help our partners to accelerate their businesses.

In other words: we are in a unique position, doing new things that nobody has done before. At the same time, this also means we are facing new challenges daily. Especially because we are growing quickly, and adding dozens of locations and hundreds of users every month. And that’s where you come in.


You have an IT-background, and are in the final stage of your studies. Computer science, system engineering, econometry; it doesn’t matter to us. What we care about is that you’re someone whose eyes start to twinkle when seeing all the possibilities that TAPP and its unique pool of data enable. Someone who feels how big the opportunity is that TAPP’s position offers. And wants to be part of this game-changing initiative.

So, what exactly is it that you’re going to do? Well, that depends on you. Are you interested in testing awesome new machine learning models? Developing all kinds of IOT applications? Automatically generating parsers? Or do you like developing new visualizations that allow us to more effectively communicate our information? It’s all relevant to us. It’s the way you want to match your background with your internship that determines which of these projects you’re going to be a part of.

As long as this background allows you to contribute to our quest of revolutionizing the hospitality industry, and you are eager to learn a lot, we are very interested in talking with you to see how you can fit into our activities.
