Job description

THE ROLE

Our customers trust us to keep their networks out of the news. You are the person who makes that true. You analyze what is really happening on a customer's network, decide what matters, and configure the controls that stop the next attempt. You work in our Global Security Operations Center (GSOC) in Zaltbommel, part of a global team that runs 24x7. One shift you untangle a routing problem; on another you segment a customer's network into Protect Surfaces and tune the policy that guards them. Always with prevention as the goal: we stop the incident, not just report it.

What You Will Do

• Analyze anomalies, alerts and threats, and decide what is real
• Fix security issues in routing and networks

Working in shifts

Our SOC does not close.

We Work In Shifts To Ensure 24/7 Security For Our Customers, Alongside Colleagues In Europe And The US. You Will Work a Rotating Pattern

• Two morning shifts (06:00 - 14:30)
• Two afternoon shifts (14:00 - 22:30)
• Two night shifts (22:00 - 06:30)
• Followed by 4 days off

How we work with AI

AI is built into our service, not bolted on: MDR Detect runs AI-assisted case handling behind our 24x7 human-led GSOC. We also build our own bespoke AI tooling on top of our platform, and the specialists who use it help shape it.

We expect you to understand prompting (structure and context change the answer), reuse (turn a repeated prompt into a skill), verification (a model can be confident and wrong) and privacy (know what goes into which tool). Not an expert yet? Curious and honest about the gaps is what matters.

Job Requirements

Who you are

• You pull the thread until you understand it
• You can say "I don't know yet" and then go find out

The rest

• Willing to join a 24x7 shift rotation
• On-site: this is not a hybrid role, and you live within ~50 minutes of Zaltbommel

• Colleagues who teach and unlimited learning: training, certification and the time to do it
• 24 vacation days (option to buy more), mobility allowance, shift compensation, catered lunch

Our customers are hospitals, research labs, retailers, banks and manufacturers. When you catch something early, their operation keeps running and the people who depend on it never notice anything happened. That is the point of the job.
