We are working on creating a future-proof data landscape, for which our team works on building/managing reference data management and a master data management solution.

We need your help to build and integrate these solutions with the rest of the KPN departments.



At the moment, the team is working from home. After Covid, you will probably sometimes work at the office and sometimes from home. Our office is at Sloterdijk, Amsterdam, where we work together with three other scrum teams on the same floor. Together we created a really fun and inspiring place to work.



You will be working with 3 other curious developers, a PO, a Scrum Master and a Data Steward.


Our Way of Working

Within the data office department of KPN, we have adopted Agile and work according to the Scrum methodology. We are convinced of the value of “We Make-We Own” and have embedded DevOps in our development teams. We aim for the best results by hiring best-in-class developers and giving the teams as much autonomy as possible. We believe we have created an inspiring environment for personal development and a great and fun place to work!
