Be part of something bigger
At Sizewell C, we’re building one of Britain’s most important infrastructure projects, a new nuclear power station on the Suffolk coast that will play an important role in the UK’s energy future.
With a project of this scale and complexity comes the need for brilliant assurance. We need confidence that the right things are being looked at, the right risks are understood, and assurance activity across the organisation is connected, coordinated and giving our leaders the insight they need.
That’s where you come in.
We’re looking for an experienced Integrated Assurance Lead to help operate and continuously improve integrated assurance across Sizewell C, bringing together assurance activity across the Three Lines Model and helping create a clear enterprise wide view of assurance coverage, risks, gaps and emerging themes.
Why join Sizewell C?
This is your chance to play a key role on a nationally significant, highly complex and regulated infrastructure programme.
You’ll join Sizewell C at an incredibly exciting stage of its development, working across a diverse organisation and helping strengthen how we connect risk, controls and assurance to support better decision making.
You’ll be working with teams across Finance, Commercial, PMO, Quality, Internal Audit, Independent Nuclear Assurance, Safety, Security & Assurance and other areas across the business.
Why join us as our Integrated Assurance Lead?
This isn’t a role where you’ll sit on the sidelines reviewing assurance activity.
You’ll be at the centre of it, connecting assurance providers and business teams, challenging where something doesn’t quite add up, spotting gaps and duplication, and turning complex assurance information into clear insight.
Stakeholder management is a huge part of this role. You’ll need to be comfortable going back and forth with stakeholders to get the right information, build strong relationships and provide constructive challenge. Crucially, you’ll know how to read the room and adapt your approach, whether you’re working with operational colleagues, functional leaders or senior executives.
You’ll also take day to day ownership of the Integrated Assurance and Audit Plan, bringing together inputs from multiple assurance providers and ensuring activity, ownership, timing, outputs and dependencies remain visible and current.
What you’ll be doing
As a Integrated Assurance Lead you’ll:
Operate and continuously improve the Integrated Assurance framework, procedures, guidance and ways of working
Manage and maintain the Integrated Assurance and Audit Plan
Coordinate assurance activity and inputs across the Three Lines Model
Connect assurance planning with strategic objectives, significant risks, controls, obligations and critical project milestones
Identify assurance gaps, unnecessary duplication, common findings and emerging themes
Develop clear dashboards, reporting and thematic analysis for senior management and governance forums
Track assurance activity and actions, constructively challenging delays or incomplete information where needed
Build strong relationships with assurance providers, functional leaders and delivery teams across Sizewell C
Support governance arrangements through clear papers, decisions, actions and follow up
Assess the quality and relevance of assurance information and highlight limitations clearly
Support the effective use and continued development of assurance systems and digital tools, including OaSIS Phase II
Help strengthen understanding of integrated assurance and the Three Lines Model across the organisation.
What we’re looking for
The hiring team is looking for someone who really understands assurance, rather than someone with only adjacent risk or audit exposure.
Ideally, you’ll bring around 5 to 7 years’ relevant experience, alongside:
Strong experience across assurance, risk, controls, audit, governance, compliance or quality in a large, complex or regulated organisation
A strong working understanding of integrated assurance and the IIA Three Lines Model
Experience operating an assurance framework or enterprise-wide assurance planning process
Experience managing assurance plans or portfolios and coordinating multiple assurance providers
A strong understanding of risk-based assurance and how organisational objectives, risks, controls and assurance activity connect
Excellent stakeholder management, influencing and relationship building skills
Confidence providing constructive challenge and working with stakeholders at all levels, including senior and executive audiences
Strong analytical skills with the ability to identify gaps, duplication, emerging themes and areas of limited assurance
Experience producing meaningful assurance reporting, dashboards and governance materials
The ability to work autonomously, manage competing priorities and exercise sound judgement.
A relevant degree is welcomed, but strong, directly relevant professional experience is equally important. Relevant professional qualifications or memberships are also desirable, including those from the Institute of Risk Management, Institute of Internal Auditors, Association for Project Management, ICAEW, ACCA or CIMA.
Experience within nuclear, energy, utilities, construction, major infrastructure or another complex, highly regulated environment would be particularly valuable.
Ready to bring assurance together?
For this role you must have evidence of right to work in the UK. As a project, we do not discriminate on the grounds of age, gender, race, colour, religion, disability or sexual orientation, and we welcome applications from all sections of the community.
