About the department

We are looking for a DevOps Engineer to strengthen one of the fulfilment Squads within KPN TDO Network CTN Arrange. Purpose of the position is to give shape to the tooling for fulfilment of network connections for the KPN organization in a self-organizing team. This is done using Agile work methods (e.g. Scrum, Kanban etc.), where the efficiency of the team in producing value is continuously improving.

Within KPN TDO Network CTN Arrange we aim to use so called T-shaped profiles. I.e. all employees have the same function (DevOps Engineer), and all work could in principle be done by everyone in the team. However, all employees have a specialization or specific knowledge in a certain area of the work. Most of the time employees will be working on items that are within their area of specialization.

About the position

You will work as a DevOps Engineer; you are a developer and integrator of network provisioning applications primarily used for authorization of the IP connections for KPN customers that require access to their requested services. The applications are based on the RADIUS and DHCP protocol and positioned in the network between the E2E fulfilment chain, the E2E assurance chain and the E2E client-server network chain (to customer premises) which makes integration very challenging.

  • A proactive mind set and natural curiosity for new technologies.
  • Experience with software development and integration of large-scale applications based on continuous delivery.

  • To collaborate within a multidisciplinary team.
  • Working both alone and with your teammates to make sure value is delivered fast!
  • Working Agile/scrum with the Agile mindset.
  • Working in a complex innovative and dynamic environment.
  • To take new challenges in a complex and fast changing environment.
  • To take risks and show a flexible attitude towards your team.
  • To continuously improve.


You must have experience in:

  • Perl or similar programming languages
  • SQL/MySQL.
  • Virtualization/Containerization (Docker).
  • Linux.
  • CI/CD integration (e.g. Git, Ansible, Jenkins, Azure DevOps,).

  • Test automation
  • Affinity with operational work (DevOps).
  • Telecom and network knowledge.
