We are very proud of the fact that we have been named by LinkedIn as a top start-up to work at for the second time in a row, together with many other prestigious awards we’ve received since our start in 2017.

We have a strong focus on scaling up internationally.

At felyx we believe that the best workplace is one that represents the world we live in today. This means we believe that diversity in the broadest sense of the word connects us and drives us forward as a company.

We believe that diversity goes hand in hand with different perspectives. It is these different perspectives that can help us become better and more innovative in finding solutions for our customers.

And because we believe this can be achieved, we are looking for colleagues who are intrinsically motivated and bring the right experience. Gender, age, sexual orientation or origin will never be a factor and will never become one.
