Power up your career with Sizewell C
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.
Sizewell C is responsible for the design, construction, commissioning, operation and eventual decommissioning of the nuclear power plant and associated infrastructure in Suffolk, operating within a highly regulated environment under the Regulated Asset Base model.
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.
Why Join Us as a Specialist Controls Manager?
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.
