What you’ll do:

• Own the end-to-end test strategy for your workstream — defining how to prove that the full integrated flow works correctly across multiple services, domains, and systems.
• Test across system boundaries — verifying integration between new platform services, legacy systems, and external platforms (e.g. card schemes, partner systems, upstream channels).
• Drive parity validation — proving that new platform flows produce the same outcomes as legacy for migrated functionality, defining what “equivalent” means, and building the comparison approach.
• Define and manage cross-system test scenarios — the integration paths and edge cases that no single scrum team would own or think to test. Build shared test infrastructure — frameworks, test utilities, event assertion tools, and data comparison tooling that support end-to-end validation.
• Create and curate test data — building representative datasets that exercise the full flow across system boundaries, institution configurations, and transaction scenarios.
• Work across scrum teams — coaching developers on integration testing approaches, ensuring teams understand the upstream and downstream impact of their changes.
• Contribute to CI/CD quality gates — ensuring automated integration tests provide fast, reliable feedback without becoming a deployment bottleneck.
• Identify integration risks early — the failure modes that live at handoff points between systems, where most defects in distributed architectures actually occur.
• Collaborate with the Quality Architect on programme-level standards and cross-workstream concerns.
