  • You’re motivated and a team player.
  • You are solution-oriented.
  • Knowledge of CRM, accounting and business systems is an asset.

What do we offer?

Of course, you will be well rewarded for delivering our customers’ projects in time and without problems. This starts as early as your first day, where you end up within a close and well-attuned team that are all passionate and motivated to deliver the best CRM to demanding and inspiring customers.

Our values ‘Openness’, ‘Efficiency’ and ‘We care’ do not only apply to our customers, but of course also to our employees. You will therefore work in one of our spacious offices where relaxation areas, a weekly fruit basket and quality coffee are standard.

And it goes without saying that there is plenty of room for a healthy work-life balance. As we are a company in full growth, you are in control of your own future.

Last but not least, we offer fun… a lot of fun! Besides ending up in an office with a pool table, we organize game nights and themed meals, as well as ‘End of Year Challenges’ and the now famous annual trip.
