QA Test Engineer

Responsibilities

• Define and evolve automation strategy across one or more product areas, aligning test coverage to real operational risk.
• Ensure acceptance criteria are clear, testable, and aligned to system behaviour and production impact.
• Build and maintain automated tests across appropriate layers of the test pyramid, with strong API and contract-level coverage.
• Reduce reliance on brittle end-to-end tests by strengthening service-level and boundary validation.
• Integrate automated testing into CI/CD pipelines with meaningful reporting and quality gates that improve release confidence.
• Collaborate early in design discussions to improve system testability and prevent defects before implementation.
• Validate distributed and event-driven workflows, including asynchronous processing, retries, idempotency, and cross-service interactions.
• Design repeatable, environment-safe test data strategies.
• Contribute to performance, resilience, and reliability validation.
• Ensure authentication, authorisation, and tenancy boundaries are correctly enforced.
• Lead root cause analysis for quality-related incidents and use production telemetry to strengthen future coverage.
• Improve shared testing frameworks, standards, and practices while coaching engineers on writing stronger, more meaningful tests.

Qualifications

• Strong experience designing and implementing automation strategies for API-first or distributed systems.
• Deep understanding of the test pyramid, risk-based testing, and automation-first principles.
• Proven experience with API automation and contract testing approaches.
• Experience with modern UI automation tools (e.g. Playwright or similar) where appropriate.
• Comfortable working in strongly typed ecosystems, ideally within .NET / C# environments.
• Practical SQL skills for data validation, troubleshooting, and investigation.
• Experience working in CI/CD environments with automated quality gates and integrated test reporting.
• Familiarity with containerised environments such as Docker.
• Strong understanding of microservices patterns, distributed system risks, and failure modes.
• Experience validating asynchronous and event-driven workflows.
• Working knowledge of authentication and authorisation concepts such as OAuth2 and OpenID Connect.
