You'll act as the payroll subject matter expert, leading on payroll delivery, compliance, systems improvement and stakeholder support while helping to shape the future of payroll operations at Sizewell C.

Working closely with the Payroll, Pensions & Reward Manager, you'll play a key role in ensuring payroll is delivered accurately and efficiently for our growing workforce. You'll also have the opportunity to support system enhancements, drive process improvements and deputise for the Payroll Manager, giving you genuine responsibility and visibility across the organisation.

The Opportunity

As Assistant Payroll Manager, you will be responsible for the day-to-day management and delivery of payroll activities, ensuring employees are paid accurately, on time and in accordance with statutory, contractual and organisational requirements. You'll oversee payroll processing, maintain robust controls, manage reconciliations and provide expert payroll guidance across the business.

Key responsibilities include:

• Managing end-to-end payroll processing activities
• Reviewing payroll transactions, reconciliations and controls
• Supporting payroll sign-off and governance activities
• Acting as an escalation point for complex payroll queries
• Supporting audits, compliance and legislative updates
• Leading payroll-related projects, process improvements and system enhancements

What We're Looking For

We're seeking an experienced payroll professional who thrives in a fast-paced environment and enjoys balancing operational delivery with continuous improvement.

You'll ideally have:

• Significant experience working within an in-house payroll function
• Strong knowledge of UK payroll legislation, HMRC requirements and statutory payments
• Experience managing end to end payroll processes and complex payroll transactions
• Excellent payroll reconciliation, validation and reporting skills
• Strong Microsoft Excel capability

Bring your payroll expertise, drive continuous improvement, and help power the future of Britain with Sizewell C. Apply today and be part of something extraordinary.

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.
