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 Qualifications
