Security Solution Architect

A job at Proximus? You'll find that everything revolves around the idea 'Think Possible'. This means: we always assume that something is possible, even if it seems impossible. Well, especially so, actually. Call it a way of thinking that involves being open to a world of digital solutions that make our lives easier. And our way of working smarter.

Task Description:

As a Security Solution Architect you will be in charge of drawing up the appropriate cyber and physical security measures for application, infrastructure and data landscape, based on the security/system requirements and policies to protect the Proximus assets. You will work on roadmap and projects related to a suite of solutions including new technologies and leadership solutions.

You will work in collaboration of Enterprise Security Architects, Proximus CSIRT and different Proximus security teams (network, security governance and management) and Cyber/Physical engineers.


  • Analyzing the potential path forwards for projects affecting the Proximus security echo-system
  • Translating new security initiatives into project end-to-end architecture and roadmap taking into account the Proximus target architecture and non-functional requirements.
  • Designing and documenting solutions, taking into account functional and non-functional requirements such as availability, performance, scalability and security

  • You have a IT or security Master's degree or equivalent by experience.
  • Security certifications (CISSP as example) is a plus.
  • 5 years experience in the security domain is a plus
  • 5 years experience in IT architecture/design is a plus.
  • You are good at identifying security flaws/risks in IT solutions and know how to deal with these.

  • You are keen to contribute to the development of a new discipline.
  • You speak French or Dutch and have an excellent command of English.

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.

In a nutshell … We offer you a job full of opportunities to grow and learn, a job that will push you forward, as you shape the digital future with us. And in doing so, you might achieve more than you thought possible. Are you a professional who thinks like this? Someone who sees solutions where others only see obstacles. Then you are a talent that can still grow with us. Every day.
