  • You cross-check results against source documents such as Excel settlements, SEPA files and migration output. All outcomes are documented clearly and systematically.
  • You log defects in Azure DevOps, assign priorities and retest fixes.
  • You collaborate with analysts and developers to identify root causes, challenge fixes where needed and ensure correct resolution before release.
  • You keep project leaders and QA informed through clear reporting.
  • You maintain a reliable regression test suite covering critical flows. You support key users during UAT and help formalise findings, gaps and improvements for upcoming releases.
  • You contribute to improving test standards, tooling, processes and testability across the team.
