• Engage with senior stakeholders across business, operations and programme leadership
• Lead escalation of critical acceptance risks and support go/no-go decision-making processes

Risk, issue and quality oversight

• Maintain consolidated oversight of acceptance-related risks and issues across UAT and EUA
• Ensure timely escalation and resolution of critical blockers impacting programme delivery or client readiness
• Define and monitor KPIs and quality metrics for acceptance activities
• Ensure compliance with internal governance, audit and regulatory expectations

Business and market readiness

• Ensure alignment between acceptance outcomes and overall business and market readiness
• Support transition from testing into migration, cutover and go-live phases
• Ensure acceptance deliverables are complete, auditable and aligned with regulatory requirements

Your profile:

• Extensive experience in senior testing, acceptance or programme leadership roles within financial services or market infrastructure

• Deep knowledge of post-trade services, settlement agents or custodians
• Experience managing client testing phases (EUA, industry testing or market-wide migrations)
• Familiarity with IEEE testing standards; ISTQB or similar certifications highly preferred
• Practical understanding of test automation and AI tools for UAT efficiency
• Strong leadership, governance and stakeholder management skills, including client-facing interactions
• Ability to manage complexity, ambiguity and competing priorities across multiple entities
