And you will get to do that within the most renowned hospital in the field of cancer: the Antoni van Leeuwenhoek.

At the Antoni van Leeuwenhoek, we work with more than 3200 employees on the best oncological care and innovative research. Robust and scalable infrastructure plays a central role in this.

To this end, we manage two data centers and a complex application landscape. The research institute possesses state-of-the-art medical equipment for which the team provides support, thereby contributing to groundbreaking research. We work incredibly hard on optimizing our processes, so that no challenge regarding information security, management, or continuity is too great for us. We need your reinforcement for all these ambitions!
