• Develop and coordinate the client-side UAT strategy, scenarios, schedules and acceptance criteria.

• Engage and coordinate business stakeholders and UAT testers.

• Manage UAT progress, defect triage, prioritisation and retesting.

• Ensure requirements traceability across business, functional and technical requirements.

• Identify testing gaps, quality risks, unresolved defects and readiness concerns.

• Assess operational readiness, service acceptance and testing completion.

• Produce assurance reports and evidence-based recommendations to support programme governance and go/no-go decisions.

• Constructively challenge suppliers and delivery partners where testing quality or evidence is insufficient.

Essential Skills & Experience

• Minimum 5 years' experience in Test Assurance, Test Management or Test Leadership within complex technology programmes.

• Proven experience in independent, client-side test assurance and supplier oversight.

• Strong understanding of the end-to-end testing lifecycle, including system testing, integration testing, UAT and operational acceptance.

• Demonstrable experience developing and leading business-led UAT.

• Experience establishing test governance, quality gates and entry/exit criteria.

• Strong knowledge of requirements traceability, test coverage and evidence-based assurance.

• Experience managing defect triage, prioritisation, resolution and retesting.

• Experience working across multi-supplier or systems integration environments.

• Excellent stakeholder management and communication skills, including engagement with senior programme stakeholders.

• Confident in challenging suppliers and providing objective assessments of testing quality and readiness.

Desirable Experience

• Previous experience as a dedicated Test Assurance Lead or Independent Test Assurance Lead.

• ISTQB certification, ideally Advanced Level Test Manager.

• Experience with Azure DevOps, Jira, Xray, Zephyr or HP ALM.

• Knowledge of Agile, Waterfall or hybrid delivery methodologies.

• Experience in large-scale infrastructure, engineering, public sector or regulated environments.

The Ideal Candidate

You will be a pragmatic and experienced Test Assurance professional who understands the difference between managing supplier testing and independently assuring its effectiveness.

This role requires someone who can combine strong governance and assurance expertise with a hands-on approach to ensuring solutions are fully tested, fit for purpose and ready for operational use.
