Key areas of focus :

• Define the blueprint for a new Payroll & HR systems ecosystem, shaping the transition from legacy to future state.
• Own the migration plan - from system build through to testing, deployment, and post‑go‑live success.
• Simplify and standardise processes, aligning them with the business’s strategic vision.
• Deliver measurable outcomes - financial, operational, and strategic.
• Lead cross‑functional teams and collaborate across the business to make transformation happen.
• Influence senior stakeholders to secure buy‑in and drive alignment at every stage.
• Champion change with strong communication and engagement plans that ensure readiness and adoption.
• Work closely with the PMO to ensure governance, reporting, and project delivery stay on track.

What you'll bring :

• Proven expertise leading end‑to‑end transformation programmes in Payroll and HR environments.
• Deep understanding of SAP, HR system architecture, integrations, and data migration.
• Hands‑on experience in business case development, blueprint design, testing, and deployment.
• A track record of delivering payroll system integrations and measurable business benefits.
• The ability to communicate complex change with clarity and impact to senior stakeholders.
• Sharp attention to detail, strong project governance, and the confidence to hit the ground running.
• Flexibility to travel nationally when required.

This is a unique opportunity to shape the future of a major organisation - driving a transformation that will leave a lasting legacy. You’ll operate at the strategic core of a business that’s evolving fast and ready to invest in change done right.

This is a hybrid role with a combination of working from home and travel between the London, Newcastle and South Yorkshire offices.

This role is a 12-month FTC with an exciting package on offer.
