The Opportunity

Are you brilliant at bringing structure to complex information, coordinating multiple stakeholders and making sure important processes are followed from beginning to end?

Sizewell C is looking for an organised, proactive and detail focused Information Disclosure Coordinator to join our Economic Regulation team.

Sizewell C works with a number of key stakeholders, each with different requirements for the secure exchange of information. As a nuclear site licence holder and majority HM Government owned company, we must comply with strict regulatory, contractual and confidentiality requirements when sharing information.

You will take ownership of our Information Disclosure workstream, overseeing the daily management and quality assurance of our Virtual Data Room and coordinating requests for information across the business. You will make sure the correct checks, permissions and processes have been completed before information is shared with regulators, shareholders, government representatives and other external stakeholders.

This is an excellent opportunity for someone who enjoys being at the centre of a process, connecting people, maintaining high standards and confidently moving work forward.

Why Join as an Information Disclosure Coordinator?

Develop your knowledge of information disclosure within a highly regulated environment
Shape and improve processes as the organisation continues to mature
Take ownership of visible, meaningful work that protects the project from disclosure and contractual risks
Build experience on one of the UK’s most significant infrastructure projects

The role carries genuine responsibility. Incorrect disclosure could create project risk, while sharing information without the required consent could result in a breach of contract. Your judgement, organisation and attention to detail will therefore make a real difference.

The Role

Reporting to the Head of Economic Regulation, you will:

Lead the daily management and quality assurance of the Virtual Data Room
Coordinate requests for information across the business and work with a wide range of internal stakeholders
Make sure information is reviewed, approved and disclosed in line with regulatory, contractual and confidentiality requirements
Maintain clear and accurate procedure and process documentation

Own and maintain the trackers used across the Information Disclosure workstream
Coordinate activity across connected workstreams and keep actions moving forward
Support the wider Information Disclosure team, including an Analyst and colleagues from the Legal team
Build effective working relationships with regulators, government representatives, shareholders and colleagues across Sizewell C

What We’re Looking For

You will be someone who combines excellent organisation with the confidence to work across a complex stakeholder environment.

Essential Experience and Skills

At least two years of relevant professional experience
Experience in information disclosure management or a closely related role
Experience managing or coordinating a Virtual Data Room
Strong project management experience
Excellent stakeholder management skills
Strong written and verbal communication skills
Excellent attention to detail
The ability to understand an end to end process and identify what needs to happen next
Confidence working autonomously and using your own initiative to progress activity
Strong Microsoft Excel and PowerPoint skills

Desirable Experience

It would be particularly helpful if you also have:

Experience using Virtual Data Room platforms such as Intralinks or a similar system
Power BI skills
Knowledge of the Freedom of Information Act 2000
Knowledge of the Environmental Information Regulations 2004
Experience within nuclear, energy, utilities, infrastructure, government, defence, financial services, legal services or another regulated environment
Experience working with government bodies, regulators or shareholders

Ready to Bring Clarity to Complex Information?

If you are a confident coordinator who loves creating order, connecting stakeholders and making sure every detail is exactly where it should be, this could be your opportunity to make a lasting impact at Sizewell C.

Bring your organisation, judgement and drive to a project that is helping shape Britain’s energy future. Apply now and put yourself at the heart of information disclosure at Sizewell C.

To be appointed to this role, you will need to meet the criteria for Security Vetting, which will, ordinarily, require you to have been a resident of the UK for at least three of the past five years.

Be at the centre of the relationship between Government and one of the UK's most strategically important infrastructure projects.

Sizewell C is one of the largest and most significant infrastructure investments in the UK. The UK is supporting construction as both a shareholder (44.9%) and debt funder (85%). Government therefore has a critical role in supporting delivery of the power station and helping SZC realise wider benefits, including jobs, skills investment, local economic growth and sector leadership.

Reporting directly to the Chief of Staff, the HMG Engagement Lead will play a pivotal role in shaping and coordinating Sizewell C's engagement with Government, ensuring that Ministers, departments and wider stakeholders have confidence in the project and understand the role Sizewell C plays in delivering national priorities.

This is a rare opportunity for an experienced Government professional to apply their Whitehall experience within a nationally significant infrastructure project at the heart of the UK's energy strategy.

The Opportunity

This role sits within the CEO Office and will lead the organisation's Government sponsorship and institutional engagement activity.

You will help shape Sizewell C's engagement approach across Government, coordinating activity across the CEO Office including Policy and Public Affairs, our Investor Relations and Finance teams, and other functions to ensure a coherent and effective relationship with Government stakeholders.

Working closely with the Chief of Staff and senior leaders, you will:

Support ownership of Sizewell C's strategic sponsorship and institutional engagement agenda.
Develop briefing material and strategic advice for senior executives.
Coordinate engagement activity across Government departments and key stakeholders.
Support the organisation's approach to Managing Public Money, Accounting Officer responsibilities and associated Government interfaces.
Track emerging policy, political and regulatory developments that may impact project delivery.
Help ensure Government understands how policy can actively support successful delivery of Sizewell C.
Coordinate complex and sensitive requests across Government, the CEO Office and corporate functions.
Build trusted relationships across Whitehall and the wider Government sponsorship landscape.

About You

This is not a traditional stakeholder engagement or public affairs role.

We are looking for someone who understands how Government works from the inside and who can confidently operate within a complex Whitehall environment.

You are likely to bring:

Experience working within the UK Civil Service, at least Grade 6 or Grade 7 level.
Experience supporting Government sponsorship, major projects, infrastructure programmes or public accountability arrangements.
Strong understanding of how policy, delivery and Government priorities interact.
Experience preparing advice, briefings and recommendations for senior decision-makers.
Exceptional stakeholder management and influencing skills.
Strong judgement, political awareness and discretion.
The ability to navigate complexity, ambiguity and competing priorities.
Experience working across multiple stakeholders to deliver outcomes in politically sensitive environments

Particularly attractive backgrounds include:

DESNZ
HM Treasury
Cabinet Office
Infrastructure and Projects Authority
Major Projects Portfolio programmes
Nuclear and energy policy
Government sponsorship teams
Complex public-private infrastructure organisations

Why Join Sizewell C?

This role offers something few Government roles can.

You will have the opportunity to move from advising on major infrastructure projects to helping deliver one of the most important projects in the UK.

You will gain exposure across Government engagement, policy, public affairs, investor relations, communications and executive decision-making, whilst working on a project that sits at the centre of energy security, economic growth, skills development and national infrastructure delivery.

You will be part of a CEO Office with a broad remit, exceptional visibility and the opportunity to build experience across multiple disciplines whilst helping shape the future of a nationally significant project.

When joining Sizewell C, you may wonder why you are contacted by colleagues with an EDF email or see the EDF logo on portals that you access and/or documentation you receive; this is because we have partnered with EDF for the provision of a number of support services whilst we complete a successful transition out of the EDF groupAt Sizewell C we encourage and embrace diversity and how it can improve our experience and performance at work. It is a requirement that those who join us have the right to work in the UK. Whilst sponsorship may be a possibility that we can explore, we are fully committed to local recruitment where possible, and those already holding the right to work in the UK.
