Job description

Alkmaar, Netherlands | Hybrid, 3 days in office

Protect the systems that keep energy infrastructure running.

Cybersecurity decisions in an operating plant have real consequences-for safety, production and reliability. In this role, you'll help secure the industrial networks and control systems behind an established energy operator's assets in the Netherlands.

You'll combine practical engineering with risk assessment and cybersecurity governance, working closely with operations, engineering, IT and specialist suppliers. It's an opportunity to strengthen both the technology and the way OT security is managed.

The opportunity

• Make a tangible impact: protect physical energy infrastructure and support safe, reliable operations.
• Combine technical depth with influence: implement security controls while helping shape standards, procedures and system architecture.
• Solve complex operational challenges: manage cybersecurity risks where patching, downtime and system changes require careful planning.
• Build cross-functional relationships: work with engineers, operators and maintenance teams to make security part of everyday operations.

What you'll do

• Strengthen OT security: support network segmentation, industrial firewall configurations, secure remote access, privileged access management and intrusion detection.
• Assess risks and shape designs: conduct cybersecurity assessments, review proposed system changes and define security requirements for projects and modifications.
• Manage vulnerabilities: evaluate vendor advisories, coordinate remediation and identify appropriate protections when immediate patching is not possible.
• Support incident response: investigate alerts, assist recovery, identify root causes and drive corrective actions.
• Develop the security framework: contribute to the OT Cyber Security Management System (CSMS), apply IEC 62443 requirements and support audits and inspections.
• Improve resilience: maintain OT asset records, support secure configurations and ensure backup and recovery procedures are tested.
• Share your expertise: help operational teams understand cybersecurity risks and apply effective security practices.

What you bring

• A Bachelor's or Master's degree in Automation Engineering, Electrical Engineering, Computer Science, Cyber Security or a related discipline.
• Approximately 5-10 years of relevant experience across OT cybersecurity, industrial control systems, DCS, SCADA or industrial networking, with demonstrable security responsibilities.
• An understanding of operating industrial environments and how security changes can affect safety and production.
• Strong communication skills and the judgement to balance HSE, operational and project priorities.
• English language skills, and residence in the Netherlands required. Must be able to travel to the head office in Alkmaar 3 days a week.

Experience we'd value

You do not need to bring every skill below. We're interested in the depth of your experience and how you apply it:

• IEC 62443 and OT cybersecurity risk assessments; ISA/IEC 62443 certification is an advantage.
• OT network architecture, segmentation and industrial firewalls.
• NIDS, security monitoring and incident response.
• Secure remote access, endpoint protection and system hardening.
• Vulnerability and patch management.
• Windows Server, Active Directory, backup and recovery.
• Industrial protocols such as Modbus TCP, OPC, EtherNet/IP, Foundation Fieldbus and HART.
• Cyber Security Management Systems and supporting procedures.
