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 will 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.
