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

• Configure security controls along Zero Trust principles

• Work hands-on with protocols like SSH, SSL, HTTPS, SMTP and DHCP

• Document your work so the next colleague hits the ground running

• Advise customers and colleagues, and make complex things simple

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.

WHO YOU ARE

• You pull the thread until you understand it

• You can say "I don't know yet" and then go find out

• You care about doing it properly: a sloppy investigation is worse than none

• You can explain a technical problem without making anyone feel stupid

WHAT YOU BRING

Technical Foundation

• Networking at CCNA level

• Concepts network segmentation, VPN, NAT, DNS and certificates

• Security thinking least privilege, defense in depth, and how an attack moves once inside

• Systems Windows, macOS and Linux

• Protocols the common ones (SSH, SSL, HTTPS, SMTP, DHCP), and the confidence to pick up the rest

• Certifications willing to get them. We pay, you study

Ways of working

• You use AI daily and can explain how, not just that you do

• You can use git (clone, branch, commit, merge request) and write Markdown: our runbooks and AI context live in plain text under version control. This is not a developer role

• You respect confidentiality: customer data does not go just anywhere

The rest

• Excellent English, spoken and written

• Willing to join a 24x7 shift rotation

• On-site: this is not a hybrid role, and you live within ~50 minutes of Zaltbommel

• Pre-employment screening, due to the sensitive nature of the job

Nice to have: experience with Palo Alto Strata or Cortex, Microsoft Defender or Fortinet FortiGate; SOC, NOC or managed services experience; Dutch; Python, Bash or similar scripting.

WHAT WE OFFER

You will grow fast, because we make sure of it.

• A clear path Junior to Medior to Senior, with explicit criteria for each step

• Cutting-edge technology for customers all over the world; no two environments are the same

• 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.
