Develop, own, and refine the migration test strategy, scope, and approach, aligned with delivery milestones and sprint cycles. Work closely with data teams to interpret, validate, and challenge data migration mappings and object models. Oversee ETL testing to ensure correct extraction, transformation, and loading of data into the target platform. Validate data accuracy, completeness, integrity, and reconciliation against source systems, business rules, and detailed mapping specifications. Update and maintain test scripts, documentation, and mapping artefacts in line with evolving data models and migration logic. Collaborate with business, technology, and data architecture teams to ensure full end-to-end testing coverage. Drive defect management, including triage, prioritisation, and timely resolution. Provide clear, concise reporting to senior stakeholders, articulating risks, issues, and decisions required. Assertively manage challenging stakeholders, lead tough conversations, and push back where necessary to protect quality and timelines. Support readiness testing, go-live validation, and post-migration checks.
