Are you laid back, slow, and meticulous, and do you think illogically? Then this might be the job for you!

Laid back because you don’t like to do things more than once if you can avoid this with smart IT solutions.
Slow, and meticulous because you don’t understand why people often choose just one operating system that’s called Windows.
Think illogically and do not only have a focus on the technical part of an IT job but always think customer service oriented and you are result driven.

You have the following capabilities:

  • You have a bachelor’s or master’s degree in IT.
  • On top of your IT studies you have a passion for system engineering (really!)
  • Theoretical knowledge and practical experience with 3CX. Asterisk is nice to have.

  • You are comfortable in English, both written and spoken (this is a must, you will communicate and read/write documentation in English)
  • You have a flexible work style and are open to out-of-office hours migration work (we assume that this is not a surprise)
