Why Join as a Payroll Specialist?

This is an excellent opportunity for someone with payroll administration experience who enjoys working with data, solving problems and providing excellent customer service. You'll be joining a growing in-house payroll team at an exciting stage of its journey, supporting the delivery of an accurate and efficient payroll service for a rapidly expanding workforce.

You'll work closely with HR, Finance and employees across the business, gaining exposure to payroll operations, compliance activities, reporting, systems improvement and payroll projects. It's the perfect role for someone looking to build on their payroll experience and develop their career within a major organisation.

The Opportunity

Reporting to the Payroll, Pensions & Reward Manager, you'll provide administrative and operational support to the in-house payroll function, helping to ensure employees are paid accurately and on time every month. You'll process payroll transactions, maintain employee records, respond to payroll queries and support a customer-focused payroll service.

Key responsibilities include:

• Processing payroll transactions including starters, leavers, contractual changes and salary amendments
• Maintaining accurate payroll records and employee data
• Supporting payroll validation checks and reconciliations
• Responding to payroll-related queries from employees and managers
• Supporting payroll compliance and year-end activities
• Producing payroll reports and management information
• Assisting with payroll process improvements and system enhancements
• Supporting payroll audits and documentation activities

What We're Looking For

We're looking for someone who is highly organised, detail-focused and confident working with data in a fast-paced environment.

You’ll ideally have:

• Previous payroll administration or payroll support experience
• Strong administrative and data processing skills
• Excellent attention to detail and accuracy
• Advanced Microsoft Excel skills
• Experience handling confidential and sensitive information
• Strong numerical and analytical skills
• Great organisational skills and the ability to manage multiple priorities
• A customer-focused approach with excellent communication skills
• Payroll systems experience (SAP or SuccessFactors experience is beneficial but not essential)

Join a team where your work directly supports one of the UK's most significant infrastructure projects. If you're passionate about accuracy, enjoy working with data and want to develop your payroll expertise in a supportive and ambitious environment, we'd love to hear from you.

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.
