We’re looking for an experienced Specialist Controls Manager to join Sizewell C and take a leading role in strengthening how we manage Fraud & Error Risk and material controls across one of the UK’s most significant infrastructure projects. This is a senior, influential role for someone with strong technical expertise who understands what effective controls look like and, importantly, how to make them work in practice.

You’ll lead the development and implementation of our specialist controls programmes, with particular responsibility for Fraud & Error Risk Management and Provision 29 of the UK Corporate Governance Code. You’ll help turn evolving governance and regulatory requirements into practical, proportionate frameworks, processes and controls that support the business.

Working across Finance, Legal, Procurement, Supply Chain, Business Integrity, Enterprise Risk, Internal Audit and the wider organisation, you’ll provide constructive challenge, identify areas for improvement and help strengthen our approach to managing significant risks. We’re particularly interested in someone with strong practical Fraud & Error expertise who understands how fraud risks arise within complex organisations and supply chains, and how effective preventative and detective controls can protect financial integrity, regulatory compliance and organisational value.

Why Join Sizewell C? Sizewell C is being built to play a major role in the UK’s energy future, providing reliable low-carbon electricity while creating jobs, developing skills and supporting long-term economic growth. Behind a project of this scale sits an equally important challenge: establishing the governance, risk management and control arrangements needed to support its successful delivery and future operation.

You’ll be joining at a time when we’re continuing to develop and strengthen our approach to risk management and internal controls. That means you’ll have the opportunity to shape frameworks and processes, work with senior decision-makers and see the impact of your expertise across a complex organisation with significant commercial activity and an extensive physical supply chain.

This is an opportunity to take ownership of significant controls programmes and help shape how they operate across Sizewell C. You won’t simply be maintaining existing frameworks or overseeing routine testing. You’ll be developing and embedding our approach to Fraud & Error Risk Management, while helping establish the processes, methodologies and governance needed to support effective material controls under Provision 29.

You’ll have the opportunity to work on complex and varied challenges, from fraud risks within procurement and supply chains to the design, assessment and monitoring of controls that support our most significant business objectives. You’ll work closely with senior stakeholders, have the autonomy to exercise your professional judgement and play an important role in strengthening the organisation’s control environment.

If you enjoy solving complex problems, challenging established approaches and building practical solutions that make a difference, this is an opportunity to apply your expertise on a project of national significance.

Reporting to the Head of Enterprise Risk, Controls & Assurance, you’ll be responsible for leading the development, implementation and continuous improvement of Sizewell C’s specialist controls programmes. Your primary focus will be Fraud & Error Risk Management and Provision 29, working closely with the wider Internal Controls team to ensure our frameworks and methodologies are consistent, proportionate and effective.

As a Specialist Controls Manager you’ll:

• Lead the development and implementation of our Fraud & Error Risk Management Framework, establishing clear arrangements for risk assessment, prevention, detection, investigation, monitoring and reporting.
• Work with stakeholders across the business to identify and assess fraud and error risks, including those arising from procurement, supply chain activities, financial transactions and third-party relationships.
• Develop and embed proportionate preventative and detective controls, ensuring appropriate ownership, documented procedures, supporting evidence and ongoing monitoring.
• Establish effective processes for identifying control gaps, agreeing remedial actions and monitoring their implementation.
• Support the development of fraud risk reporting and governance arrangements, ensuring significant exposures, weaknesses and emerging issues are appropriately escalated.
• Apply your knowledge of the Economic Crime and Corporate Transparency Act and relevant government fraud prevention requirements to help strengthen our approach to managing fraud and error risks.
• Lead the continued development and implementation of our approach to Provision 29 and material controls, supporting Sizewell C’s readiness for evolving corporate governance requirements.
• Develop and maintain methodologies for identifying, assessing and documenting material controls, ensuring clear connections to significant risks, business processes and obligations.
• Work with senior management, control owners and subject matter experts to confirm control ownership, validate control descriptions and establish appropriate evidence requirements.
• Coordinate the assessment of control design and operating effectiveness, including the development of testing approaches, evaluation of findings and monitoring of remediation activities.
• Support management attestation processes and the preparation of reporting on material controls, significant deficiencies and control effectiveness.
• Work closely with the Internal Controls team to ensure alignment with the wider Internal Controls Framework, including risk and control matrices, testing methodologies, evidence standards and deficiency management.

Wider Responsibilities:

• Provide credible technical advice and constructive challenge to senior leaders and control owners, including navigating complex or sensitive issues.
• Lead cross-functional workstreams, establishing clear delivery plans, responsibilities and milestones, and ensuring agreed actions are progressed.
• Identify themes and weaknesses across organisational boundaries and translate them into practical recommendations for improvement.
• Prepare clear, evidence-based reporting and recommendations for Executive management, the Audit & Risk Committee and other governance forums.
• Keep pace with developments in corporate governance, economic crime, fraud prevention and internal controls, assessing their implications for Sizewell C.
• Represent Enterprise Risk, Controls & Assurance within relevant governance forums and deputise for the Head of Enterprise Risk, Controls & Assurance where required.

What We’re Looking For:

We’re looking for someone with at least 7 years’ relevant experience across fraud and error, internal controls, risk, assurance, governance or a related discipline, ideally gained within a large, complex or highly regulated organisation. Most importantly, you’ll bring strong practical Fraud & Error Risk Management expertise, together with the ability to develop and implement effective controls arrangements.

You’ll understand how fraud risks arise, how preventative and detective controls should operate, and how to build the processes and governance needed to support a sustainable and effective control environment. You’ll be comfortable leading complex workstreams, working across organisational boundaries and providing constructive challenge to senior stakeholders.

The successful candidate will bring:

• Strong knowledge and practical experience of fraud and error risk management, including fraud risk assessment, prevention, detection, monitoring and remediation.
• Experience developing, implementing or improving fraud risk management frameworks, fraud prevention arrangements or significant controls programmes.
• Strong internal controls experience, including risk and control matrices, control documentation, design and operating effectiveness testing, evidence, deficiencies and remediation.
• Knowledge of the Economic Crime and Corporate Transparency Act and its implications for fraud prevention and organisational controls.
• Experience translating regulatory, governance or policy requirements into practical processes and controls.
• Experience leading complex, cross-functional programmes and working with stakeholders across Finance, Legal, Procurement, Supply Chain and other business functions.
• The confidence to constructively challenge senior stakeholders, exercise sound professional judgement and manage complex or sensitive issues.
• Strong analytical skills, with the ability to assess incomplete or conflicting information, identify control weaknesses and recommend proportionate improvements.
• Experience preparing clear, concise reporting for senior leadership, Executive or Audit & Risk Committee audiences.
• Strong Microsoft 365 and Excel capability.
• Experience working within complex physical supply chains, particularly in major infrastructure, construction, nuclear, energy, utilities or another asset-intensive environment, would be advantageous.
• Knowledge or direct experience of UK Corporate Governance Code Provision 29 would be particularly valuable, although we’re equally interested in candidates with strong transferable controls expertise who can interpret and apply evolving requirements.
• Experience using SAP, implementing enterprise-wide Fraud & Error programmes or working with government fraud prevention requirements would also be beneficial.

Qualifications:

You’ll have a relevant professional qualification or demonstrably equivalent professional experience within finance, fraud, risk management, governance, assurance or internal controls. Qualifications such as ACA, ACCA, CIMA or CA would be particularly relevant, and a Certified Fraud Examiner (CFE) qualification would also be advantageous.

Ready to Make Your Mark? If you have strong Fraud & Error and controls expertise, enjoy tackling complex challenges and want the opportunity to build and improve frameworks that make a lasting difference, we’d love to hear from you. Bring your expertise, challenge established thinking and help us build the controls and processes that will support Sizewell C’s future.

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 group.

At 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. 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.
