Job Description

Our department

We, GfK Business Applications NL, are an IT division with around 25 developers spread across different Agile teams. We focus on delivering an end-to-end market research platform which is used by GfK researchers across the world.

As employee of GfK Business Application’s division you will be part of an enthusiastic group of highly technically skilled people that live and breathe software development. This department currently consists of four scrum teams. Each with their own expertise in the areas of frontend framework development, data analytics, research tools, data storage and data analysis as well as infrastructure and operations. As part of our team culture we implemented Holacracy to give the team members the ability to invest in themselves. Everyone has the opportunity to take control by changing things as they think it could benefit the teams or department. If you think something should change, change it. This is the way you, as a member of the department, can take control of your or your team’s tensions.

We value our team members, so we take great care of them by giving them the ability to invest in themselves by organising Project Fridays. Every other week we have a full day that is dedicated, across the entire department, to investigate and explore new technologies.

We also have ‘end-of-the-week’ drinks, football table competitions, poker nights, movie nights etc.
