  • Train network & IT professionals and assist in resolving operational issues.
  • You achieved a Master degree in Telecommunications / IT or equivalent by experience.
  • A minimum of 5 to10 years of experience in a similar role is an asset.

  • Thirsty to learn with an open, analytical and creative mind.
  • Excellent communication and negotiation skills.
  • English is a must.

Naturally we have a competitive salary package for you. But there is so much more!

  • We are 100% Belgian. So we make decisions in three languages. And all at the same time if you like!
  • We are open to everyone: M, W, X, and in fact all the other letters of the alphabet.
  • We encourage personal growth. At the Proximus Academy, you won't even want to miss a session.
  • We are, of course, committed to sustainability. What else did you think?
  • We firmly believe that working together is important, but that having fun together is even more so. That is why we regularly organise fun activities. (Please let us know if you have a talent for playing Santa Claus!)
  • We believe in responsibility. Also in yours. For example, you can take it to launch your own initiatives.
  • We put our customers first. And because we are all customers somewhere, you already know what that means. That's good.
  • And the ever-important work-life balance? We keep it in the right place.
