• Develop cyber security plans, requirements, risk assessments, assurance arguments and supporting evidence across the system lifecycle.
• Integrate cyber security activities with systems engineering, functional safety, commissioning, maintenance and operations.
• Support architecture reviews, supplier assessments, design reviews, verification and validation activities.
• Facilitate workshops and communicate complex technical risks clearly to technical and non-technical stakeholders.

• Experience in critical national infrastructure, energy, transport, defence, nuclear, utilities, manufacturing or other regulated sectors.
• Experience of integrating cyber security with functional safety or safety-related systems.
• Knowledge of OT network security, segmentation, zones and conduits, secure remote access, monitoring or incident response.
