About the Project
We're seeking an experienced security professional to manage the security risk management team for Sizewell C - one of the UK's most important clean energy projects.
This role is about more than assessments. You will ensure Sizewell C can anticipate, prepare for, and respond to a wide spectrum of threats and vulnerabilities across our main site, offsite infrastructure, and supply chain. By identifying and managing risks effectively, you will help protect our people, assets and operations, while also safeguarding the project's reputation, resilience, and ability to deliver at pace.
You will work closely with the construction and operations teams to support the safe delivery of their scope of works, making sure that risks are understood early and proportionate controls are built in. You will also play a leading role in building a positive security culture, ensuring that awareness, accountability, and good practice are embedded across the project and its partners.
The key challenge will be ensuring security risks are managed proportionately across a complex and rapidly evolving construction programme, while shaping a culture that makes security everyone's responsibility.
Key Responsibilities:

• Manage and develop the security risk management team, setting direction and providing mentorship.
• Conduct and review Security Vulnerability Assessments (SVAs) across project activities.
• Ensure risks are identified, recorded, tracked and addressed through the project lifecycle.
• Translate assessment findings into clear and practical Operational Requirements.
• Work closely with the construction team to support the safe and secure delivery of their works.
• Provide assurance of contract partners' security arrangements and Security Management Plans.
• Support the supply chain in identifying, documenting and implementing proportionate security measures.
• Champion and drive the project's security culture through training, engagement and leadership example.
• Collaborate with operations and offsite leads to ensure risk management outputs and cultural initiatives are embedded into daily delivery.

What You'll Bring
Essential:
We're looking for someone who can combine hands-on security risk expertise with the ability to manage people and influence across a major infrastructure project.

• Significant experience in delivering risk-based security strategies on large or complex projects.
• Strong leadership and team management skills.
• Skilled in creation of security risk assessments and producing Operational Requirements.
• Experience supporting construction or operational delivery through risk-based security planning.
• Ability to develop and embed a strong security culture across diverse teams.
• Experience in assurance of contractors and supply chain partners.
• Excellent analytical, communication and report-writing skills.
• Degree (or equivalent experience).
• Eligible to hold, or currently holding, NSV SC clearance.

Desirable:

• Background in the civil nuclear sector or other regulated/government security environments.
• Knowledge of ONR, CNC or Home Office security frameworks.
• Experience in developing policies, procedures or governance frameworks.
• Professional recognition such as Chartered Security Professional (CSyP), or certifications such as CPP (ASIS International).
• Experience in incident planning, protest management, or intelligence analysis.

Why Join Us?

Additional Information
Join the team at Sizewell C. The power of good for Britain.
It's not every day you get the opportunity to shape the working culture of what will be one of Europe's largest construction projects, while also helping Britain to reach its target of Net Zero emissions by 2050. That's one of the reasons Sizewell C will be unlike anything you've ever experienced before, and you'll need to be an exceptional professional to reach the high standards this critical infrastructure project demands.
The UK is experiencing a nuclear renaissance and Sizewell C - along with its sister project at Hinkley Point C in Somerset - is powering the change. We're ramping up at pace as we look ahead to the Financial Investment Decision in early 2025, and the start of construction soon after. With government fully on board and public opinion shifting significantly in favour of nuclear, there's never been a better time to join our project.
