Wat bieden we jou?

There is a lot that’s possible within T-Mobile but you have to take the initiative. Be enthusiastic! Are you missing something or could something be improved? Go ahead, do it differently! It’s great when you learn from us but it is equally great when we learn from you!

Our first contact will probably be by phone (off course), for a short chat with one of our recruiters. Next there can be an interview which usually will be conducted digitally online where you will meet a manager and/or a couple of colleagues. Still interested? Then there will be a second interview (digital or face to face in the office) which will be more in-depth. When afterwards you and us are still enthusiastic, we will present you an offer in which you can become the newest member of Team Magenta!

Next to about 2000 enthusiastic colleagues we also provide the following:

  • A good salary
  • Freedom to work
  • 30 + 1 vacation days on a full-time basis, plus public holidays
  • 3 interchangeable public holidays of your choice according to religion or country of origin.
  • Collective Bonus Scheme
  • Progressive Pension Plan
  • Personal annual learning budget
  • Discount on T-Mobile subscriptions Mobile and Internet & TV @ home
  • Hybrid work environment, both at home and in the office
  • Workshops, sporting outings, T-Schnee, cozy drinks and fun parties organized by Young T-Mobile.

Wat ga je bij ons leren?

At T-Mobile it goes without saying to keep personal development going. We have a variety of platforms to help you with your development. You are responsible in doing so and so you determine how, what and when you choose to develop. We will support you in this. So how do we do that?

YOU are in the lead, so old fashioned performance reviews and such, is not something we do. You keep your manager and colleagues informed about your goals and development. We call those discussions “Great conversations”. More about how this works you can see via:


Overige informatie

So,… Are you just as excited about us and this role, as we are about having you on the team? Great, then we probably are a good match. Applying is very easy. Just sent your CV and motivational cover letter via the button/link and give yourself the opportunity to be part of one of the best providers of The Netherlands where you could be part of the T-Mobile family for a long time with a bright future.

This is not a project, we are in it for the long run! Aren’t you!?
