About the Role:
The Cyber Requirements & Compliance Manager plays a critical role in ensuring Sizewell C's cyber security arrangements remain aligned with regulatory, legal, and organisational requirements.

Acting as the primary cyber security interface with the Office for Nuclear Regulation (ONR), you will drive regulatory engagement, oversee compliance monitoring, and provide assurance that cyber security controls and governance arrangements are effectively implemented across the organisation.
This is a highly visible role that requires close collaboration with senior leaders, regulators, and specialist cyber teams, supporting the delivery of a secure, resilient, and compliant organisation.
Key Responsibilities:
Regulatory Relationship & Engagement
- Act as the primary point of contact with the ONR on cyber security and information assurance matters.
- Identify, interpret, and maintain cyber security requirements arising from legislation, regulation, and industry expectations.
- Prepare, coordinate, and submit regulatory documentation and responses as required.
- Support regulatory inspections, reviews, and assessments, ensuring requirements are clearly understood and implemented.
- Manage regulatory findings, recommendations, and improvement actions through to successful closure.
