What does this job entail?

KBC customers and colleagues count on our data centres operating smoothly and securely 24/7. As Network Engineer / System Engineer you will strengthen the team responsible for this.

Together we manage four data centres. Two In Belgium, located in Mechelen and Leuven, and two in Hungary, in Torokbalint and Baracska, near Budapest. You will have colleagues in both countries, which gives the job an interesting international dimension.

  • The Group Data Centre Network Team focuses on switching & routing, DDI and network management.
  • The Group Data Centre Network Security Team focuses on firewalling.
  • The Group Data Centre Network Application Delivery Team works on load balancing, volumetric DDoS protection, secure web gateways and network management and visibility.

Because the three teams work together closely, you will be involved in all these aspects. But your specific focus is Load Balancing, Volumetric DDoS protection and Secure Web Gateways.

  • When new technical opportunities become available you will investigate whether they can optimise or automate some of our work.
  • You will analyse problems so we can resolve incidents quickly, and so you contribute to us continually improving our products and services.
  • You will contribute to our self-service offering for our internal customers. Any simple task they can do for themselves frees up time for to work on more challenging tasks.
  • We have a duty rota for urgent support outside office hours and you will take your turn in that.
  • Gradually you will take on other responsibilities and progress to a coordinating role.
