Role Purpose

The Head of Workday leads the Group IT Workday Centre of Excellence (CoE) and is accountable for enterprise platform ownership of Workday globally. Group IT owns the Workday technology platform, governance, security, integrations, service management, and technical roadmap. Business process ownership, policy design, and functional accountability remain with HR and Finance as Business Owners. The role ensures Workday operates as a secure, scalable, governed enterprise platform enabling HR and Finance to deliver business value, regulatory compliance, and operational excellence. At present, the Workday Finance platform remains in a programme delivery phase, while HCM operates in a more established BAU state. The Head of Workday will provide consistent enterprise platform governance across both domains, ensuring appropriate controls during ongoing programme delivery while maturing HCM operations within a stable BAU model.
