Senior Quality Engineer

• →Own the end to end test strategy for the Payments product team, deciding what gets tested manually, what gets automated, at which layer, and why, based on the risk each area carries.
• →Design and execute validation for payment flows including authorisation, capture, settlement, partial and full refunds, failed and retried transactions, chargebacks, idempotency, and reconciliation between our records and the provider's.
• →Advocate and support building and maintenance of automated coverage across UI, API and service layers, and keep it trustworthy.
• →Validate integrations with third party payment gateways and providers, including sandbox behaviour, webhook and callback handling, timeout and partial failure scenarios, and provider side error handling.
• →Engage from discovery and refinement onward: challenge assumptions, surface missing scenarios, and make sure acceptance criteria are specific and testable before a story is picked up.
• →Assess your team's current quality maturity honestly, build a plan to lift it over the next two to three quarters, and share what you learn with Senior QAs on other teams facing the same gaps.
• →Coach engineers on testing principles, test design, and shared ownership of automated tests, the goal is a team that builds quality in, not a QA who inspects for it.
• →Mentor mid level QA engineers on risk assessment, automation, observability and shift left practice.
• →Contribute to CI/CD pipeline health and deployment quality gates: test suite selection, environment readiness, pre and post deploy checks, and safe release strategies including feature flags and staged rollout.
• →Own production defect triage for Payments: assess customer and financial impact, distinguish severity from priority, drive fixes at the right urgency, and follow through to root cause and prevention.
• →Represent Payments quality in incident reviews and, where needed, in conversations with Support and customer facing teams.
