Shape the organisation behind one of the UK's most significant infrastructure projects.

Sizewell C is building a new generation of nuclear power for Britain. As we move from development into delivery, maintaining the organisational capability required to safely and successfully operate in a highly regulated environment has never been more important.

We're seeking an experienced Nuclear Organisational Capability Lead to take ownership of our LC36 Organisational Capability arrangements, ensuring Sizewell C continues to have the people, structures, skills and governance required to deliver nuclear safety and environmental management responsibilities

This is a rare opportunity to influence how a nationally significant project manages organisational change, workforce capability and regulatory compliance at scale.

What you'll be doing

Reporting to the Senior Organisational Capability Manager, you'll lead a specialist team responsible for organisational capability governance across Sizewell C. You'll partner with senior leaders across the business, providing expert advice and challenge whilst ensuring organisational changes are robustly assessed, governed and implemented.

Key responsibilities include:

• Leading Sizewell C's LC36 Organisational Capability arrangements.
• Owning the Nuclear & Environmental Baseline (NBEB) and ensuring its accuracy and effectiveness.
• Leading Management of Organisational Change (MoC) governance and assessment activities.
• Providing expert advice and coaching to senior leaders on organisation design, capability risk and organisational change.
• Identifying organisational capability vulnerabilities and developing mitigation plans.
• Supporting regulatory engagement with the Office for Nuclear Regulation (ONR) and Environment Agency.
• Driving continuous improvement across organisational capability processes and governance.
• Contributing strategic insight into workforce planning, critical skills management and organisational resilience.

Why this role is different

This is not a traditional HR, Organisation Development or Learning & Development role.

We're looking for someone who understands how organisational capability underpins safety, compliance and operational delivery in a highly regulated environment.

You'll play a critical role in ensuring that organisational decisions support nuclear safety, regulatory compliance and long-term project success. Your work will directly influence how Sizewell C manages capability risks, organisational resilience and strategic workforce planning.

Who we're looking for

You may currently be working in:

• Nuclear Operations
• Nuclear Safety & Assurance
• Organisational Capability / LC36
• Governance & Regulatory Compliance
• Major Infrastructure
• Defence Nuclear
• Energy, Rail, Aviation or other high-hazard industries

You'll bring:

• Experience working within regulated or high-hazard environments.
• Expertise in organisational capability, governance, assurance or organisational change.
• Strong stakeholder management and influencing skills.
• Experience interpreting complex organisational and workforce data.
• The ability to engage confidently with senior leaders and regulators.
• A proactive approach to identifying risks, opportunities and improvements.

Experience of LC36, organisational capability governance, Nuclear & Environmental Baselines or Management of Organisational Change would be highly desirable.

Why Sizewell C?

Sizewell C is one of the largest and most exciting infrastructure projects in Europe, delivering secure, low-carbon energy for generations to come. This is your opportunity to influence the capability, governance and resilience of a project that will have national significance for decades.

Join us and help build the organisation that will build Sizewell C.
