Job Introduction
Job Specification - Payroll Specialist
Working pattern: Part Time (4 days)
Contract type: Permanent
Location: Hybrid
Role Purpose
The Payroll Specialist is the in-house owner of the end-to-end payroll function. The role works in partnership with our outsourced payroll provider, Sona Payroll, to ensure that every employee is paid accurately, on time, and in line with current UK legislation.
The specialist will manage the Sona relationship, take ownership of compliance and the more complex elements of payroll (including manual payments, sick pay, and statutory calculations), and drive continuous improvement – including the use of AI and automation to reduce manual effort and risk.
This is a key role in stabilising our payroll function, releasing capacity in HR and Finance, and embedding the expertise the organisation currently lacks.
