We are looking for an experienced QA Lead to own quality assurance for our Core Ledger platform. Our team does not develop the core ledger systems ourselves — they are built and delivered by external suppliers. Your role is to set the test strategy, verify and regression test what our suppliers deliver, and make sure nothing goes live unless it meets our requirements. Since the systems involved are financial, precision and thoroughness really matter — you will be the last line of defence before a delivery is approved.

This is a newly established, hands-on position within a small team. In this initial phase, the role will not carry direct reports; instead, the focus will be on personally executing tests, developing the test strategy, and leading verification and regression testing efforts in close collaboration with the wider team.

Key Responsibilities
- Define and own the overall test strategy for the Core Ledger domain, covering functional, regression, integration, and acceptance testing of supplier deliveries
- Personally build and maintain test plans, test cases,



and (where applicable) automated regression suites
- Work with the Head of Core Ledger IT, Core Ledger Specialists, and Product Manager to embed quality from requirements through to delivery approval
- Verify and regression test ledger transaction flows, balance calculations, and reconciliation logic delivered by suppliers
- Drive a quality mindset across requirements writing, ensuring testability is considered from the start
- Investigate and triage defects, coordinating resolution with suppliers and internal stakeholders
- Define and track quality metrics; report on test coverage, defect trends, and delivery readiness
- Participate in go/no-go decisions for supplier deliveries based on quality criteria
- Support internal teams with questions about test results, known issues, and quality status
- Contribute to risk assessments for major platform changes or new product introductions
