Our client is a well-established business seeking to strengthen its People function during an exciting period of change. The role has arisen as part of a key initiative to enhance their HR systems and ensure payroll processes are robust, accurate, and future-ready.

Reporting into the People Director, this role will lead the transition to a new HR Information System (HRIS), overseeing monthly payroll processing and delivering high-quality people data and insights.

Excellent project management experience and the ability to navigate ambiguity are key, along with the flexibility to travel between sites as needed. This is a unique opportunity to take ownership of a critical people systems project, work within a supportive team, and leave a lasting impact on the organisation. If you are motivated by change, enjoy solving complex challenges, and want to play a pivotal role in shaping the future of HR systems, we would love to hear from you.
