About the role

Join our team as a Senior Cyber Security Engineer – Subsea Production Systems, responsible for designing, implementing, and maintaining cyber security solutions across subsea control systems, SCADA environments, and associated digital infrastructure. You will collaborate with system engineers, software teams, and product stakeholders to embed cyber security throughout the lifecycle of subsea production systems—from design through deployment and operation. This role requires a strong understanding of OT security, industrial communication protocols, and secure system architecture within safety-critical environments.

Responsibilities

• Design and implement secure architectures for subsea control systems, including topside and subsea communication networks
• Perform cyber security risk assessments, threat modeling, and vulnerability analysis for SPS and SCADA systems
• Define and enforce secure coding practices and design principles across PLC, HMI, and control software platforms
• Ensure compliance with relevant standards such as IEC 62443, NIST, ISO 27001, and industry-specific regulations
• Lead security reviews and audits across system designs, software releases, and project deliverables
• Support incident response and root cause analysis for cyber security events in operational environments
• Implement and maintain network segmentation, secure remote access, and monitoring controls for OT environments
• Collaborate with engineering teams to secure industrial protocols (e.g., OPC UA, Modbus TCP/IP, Ethernet/IP)
• Define requirements for authentication, encryption, certificate management, and key infrastructure within subsea systems
• Provide technical guidance and mentorship to junior engineers and project teams on cyber security best practices
• Support customer engagements, including security documentation, compliance evidence, and technical responses

Qualifications

• 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
• Have a permanent work permit in UK
