The Senior Cyber Security Engineer – Subsea Production Systems will be responsible for designing, implementing, and maintaining cyber security solutions across subsea control systems, SCADA environments, and associated digital infrastructure.

You will work closely with system engineers, software teams, and product stakeholders to ensure that cyber security is embedded throughout the lifecycle of subsea production systems—from design through deployment and operation.

The role requires a strong understanding of OT (Operational Technology) security, industrial communication protocols, and secure system architecture within safety‑critical environments.

As a Senior Cyber Security Engineer, you will be responsible for:

Designing and implementing secure architectures for subsea control systems, including topside and subsea communication networks

Performing cyber security risk assessments, threat modeling, and vulnerability analysis for SPS and SCADA systems

Defining and enforcing secure coding practices and design principles across PLC, HMI, and control software platforms

Ensuring compliance with relevant standards such as IEC 62443, NIST, ISO 27001, and industry-specific regulations

Leading security reviews and audits across system designs, software releases, and project deliverables

Supporting incident response and root cause analysis for cyber security events in operational environments

Implementing and maintaining network segmentation, secure remote access, and monitoring controls for OT environments

Collaborating with engineering teams to secure industrial protocols (e.g., OPC UA, Modbus TCP/IP, Ethernet/IP)
Defining requirements for authentication, encryption, certificate management, and key infrastructure within subsea systems

Providing technical guidance and mentorship to junior engineers and project teams on cyber security best practices

Supporting customer engagements, including security documentation, compliance evidence, and technical responses

Fuel your passion

To be successful in this role, you should have:

A Bachelor’s or Master’s degree in Cyber Security, Computer Engineering, Electrical Engineering, or a related field

Significant experience in cyber security engineering within industrial/OT environments, preferably in oil & gas or energy

Strong knowledge of industrial control systems (ICS), SCADA, and subsea production systems architectures

Proven experience with cyber security standards and frameworks (IEC 62443 highly desirable)
Familiarity with industrial communication protocols such as OPC UA, Modbus, TCP/IP, and secure communication design

Experience with network security technologies, including firewalls, IDS/IPS, VPNs, and segmentation strategies

Experience in risk assessment methodologies, penetration testing, or vulnerability management
