Work that matters
What you work on reaches the top tables in Europe. At the Benelux Summit in Maastricht, we gave a live demo of the European Business Wallet to the three Benelux prime ministers: Rob Jetten, Bart De Wever and Luc Frieden.
We showed how the wallet saves entrepreneurs a great deal of paperwork when they do business across borders. The demo ran on existing eIDAS technology from Cleverbase, together with building blocks from the WE BUILD consortium. Rob Jetten's message: “The sooner, the better.”
Everyone safe online. That is what we work towards every day.

What you bring
What we ask of you
- A relevant certificate, such as CISSP, S-CISO, CISM or GIAC. What you can do with it matters more than the certificate itself
- A few years of experience in which you shaped security yourself, for example as a security architect, security engineer, technical ISO or a pentester who wants to move to the defensive side
- Knowledge of applied cryptography, certificate profiles, key separation and HSM configuration in practice
- Enough understanding of Linux, containers, CI/CD, network segmentation and IAM to set requirements and assess implementation
- You can get to the bottom of a design, ask the right questions and weigh the answers, without having to build it yourself
- You prioritise based on risk
- You push back with well-founded arguments, including to the management team
- You write clearly, because analyses need to hold up as evidence
- Good Dutch and English, spoken and written
Nice to have
- A background as a security architect, security engineer, technical ISO or a pentester who wants to move to the defensive side
