You'll have previous administrative experience, ideally gained within payroll, HR, recruitment, learning and development or a related people services environment. A good understanding of payroll or HR systems, confidence using Microsoft Office applications and the ability to build positive relationships with a wide range of stakeholders will help you succeed in this role.

To be successful, you should have:

• GCSEs/A-Levels in English and Maths and experience in an administrative role, ideally within payroll, HR, or a related function.
• Experience using payroll, HR or business systems and maintaining accurate records and databases.
• Proven ability to handle confidential information with discretion while delivering excellent customer service.
• Strong attention to detail, data management skills, and the ability to manage competing priorities to meet deadlines.
• A CIPD qualification (Level 3 in England and Wales, Level 6 in Scotland, or equivalent), advanced Microsoft Office skills and experience using systems such as Business World, ATS or Learning Management Systems would be advantageous.
