Job Overview

• Department: People Services

• Reports to: VP People Services

• Team: Global Payroll Manager and Payroll Specialist

• Location: Remote – UK

• Contract: 12-month fixed-term contract

About the Role

Payroll across 14 countries currently operates through five delivery models: Deel (standard and EOR), Arpi in Poland, ADP as a PEO in the US, and an in-house payroll in Tunisia. The process depends on a small number of named individuals, with limited documented processes and trained backup.

We're looking for a Payroll Specialist – Project Lead to address this and establish a sustainable global payroll operating model.

This is a build role, not solely a processing role. Over 12 months, you'll document how payroll operates in each country, establish and train a primary and backup owner for every country, move all payroll onto a global operating model, and hand over the result to a permanent team, supported by a costed recommendation on how that team should be structured.

You'll work alongside the Global Payroll Manager and the Payroll Specialist, with sponsorship from the VP People Services.

The focus will be on building the new operating model during the first eight months. Your responsibility for running payroll will grow through the final phase, culminating in running payroll for all 14 countries on the new model.

What You'll Be Responsible For

1. Global Payroll Operating Model

• Lead the move of all 14 countries onto the global payroll operating model.

• Define and embed workflows between HR Operations, Finance and HRBPs.

• Strengthen and deliver the service catalogue.

2. Process Documentation & Assessment

• Document processes, calendars, cut-offs, approvals, provider interfaces and controls for each country, starting with the five priority countries.

• Capture volume and productivity data to inform the sizing of the permanent team.

3. Ownership & Continuity

• Establish a named primary owner and a trained backup for every country.

• Secure time commitments from current owners, scheduled around payroll cut-offs.

• Train backups to run each payroll.

4. Payroll Operations

• Ensure accurate, timely and compliant payroll processing, reconciliations, audits and issue resolution alongside the existing team.

• Build towards running payroll for all 14 countries by the end of the contract.

5. Capability Building

• Upskill colleagues where required on the documented model, ensuring knowledge sits with the permanent team and not with the postholder.

6. Controls & Governance

• Build documented approvals and independent reviews into each country process so Finance and auditors can evidence repeatable controls.

• Maintain regulatory compliance, statutory filing discipline and legislative awareness across jurisdictions.

7. Provider Management

• Produce a single view of how each country operates and what each provider does, establishing the baseline for a later, separate decision on provider consolidation.

8. Automation & Self-Service

• Specify self-service and automation use cases for Luna, HiBob, HR Hub and Jira ticketing systems, built on documented and standardised processes.

9. Payroll Onboarding Playbook

• Produce a standard payroll onboarding playbook so that an acquisition or new country can be absorbed into the model rather than set up with another provider and another individual owner.

10. Benefits Ways of Working

• Support the move of benefits administration individual HR Operations and payroll owners to a global operating model by capturing the as-is and setting up structured ways of working.

• Benefits management remains in HR Operations.

11. Reporting & Analytics

• Establish reporting on payroll corrections and off-cycle payments, where there is no visibility today.

• Report on progress against the delivery plan to the VP People Services.

12. Permanent Structure & Handover

• Provide the as-is, the to-be and the full cost, with a recommendation on the permanent payroll structure, for the leadership decision gate.

• Complete the handover to permanent hires with an overlap period.

13. Stakeholder Partnership

• Act as the payroll SME and collaborate across HR Operations, HRBPs, Finance, Legal, IT, country payroll owners and providers.
