We sit on top of all data that shows the call and payment behavior of our customers. Your skills and expertise will help KPN to take the right actions based on this huge set of (streaming) data.



We are protecting KPN from fraudsters and protecting customers for unexpected high bills. This we need to do 24/7!



Amsterdam / Home (and an occasional visit to Groningen)


With whom: 

We are a diverse international scrumteam of 5 persons with close interactions with various stakeholders. We support Security when lawful disclosure activities take place. We support the Fraud team to find fraudsters. And we support the contract-to-cash teams by letting them work on high usage alarms and anomalies in call behavior.


Your biggest impact:

We focus on quick detection of fraud and high usage. We ensure that all confidential data are dealt with carefully and with respect for privacy. We also play a very important role in the customer acceptance process of KPN and we recently built our own awesome front-end application in Angular that we keep extending and will be looking for other opportunities within the company to reach more departments.
