The Opportunity

We are seeking an experienced UAT Test Manager to join a large-scale SAP S/4HANA transformation and migration programme for a major public sector organisation.

This is a high-profile role requiring an experienced test professional who can operate confidently at senior stakeholder level, lead business users through a complex UAT programme, and manage multiple third-party suppliers and vendors.

You will take ownership of the UAT strategy and delivery across the programme, ensuring the organisation is fully prepared to validate the new SAP S/4HANA solution and transition successfully into business-as-usual operations.

Key Responsibilities

• Own and lead the User Acceptance Testing (UAT) strategy, planning and execution across the SAP S/4HANA transformation and migration programme.
• Develop and maintain the UAT approach, including scope, entry/exit criteria, test cycles, environments, data requirements, resources and governance.
• Lead and coordinate UAT activities across multiple business functions and stakeholder groups.
• Work closely with senior stakeholders, business leaders and subject matter experts to define business acceptance criteria and ensure appropriate test coverage.
• Manage and coordinate large groups of business users through UAT, ensuring they are appropriately prepared, supported and engaged.
• Establish effective test governance, reporting, defect management and escalation processes.
• Provide clear and concise reporting on UAT progress, risks, issues, defects, dependencies and readiness to senior programme leadership.
• Manage relationships with third-party implementation partners, testing suppliers and technology vendors, ensuring contractual and programme testing commitments are delivered.
• Challenge vendor test strategies, plans and results where necessary, ensuring appropriate quality and evidence of testing.
• Coordinate defect triage and resolution across business users, SAP teams, technical teams and third-party suppliers.
• Ensure critical business processes and end-to-end scenarios are adequately tested across the SAP S/4HANA solution.
• Work closely with the wider Programme, PMO, Change, Data, Technical and Business teams to ensure UAT is aligned with the overall transformation plan.
• Support cutover and go-live readiness by providing clear assessments of UAT completion and business acceptance.
• Identify and proactively manage testing risks, dependencies and resource constraints.
• Ensure appropriate test evidence, documentation and audit trails are maintained in line with public sector governance requirements.
• Lead UAT readiness and go-live decision-making forums where required.
