Senior QA Engineer

Responsibilities

• Attend all squad ceremonies - sprint planning, daily standup, review, retrospective - as a full member of the squad, not a downstream recipient of work.
• Define acceptance criteria with the Product Owner before each sprint, and push back on ambiguity before development starts, not after.
• Own test architecture for your squad's domain - the structure of the test pyramid, how unit, integration, contract, and E2E tests fit together, and where the squad's coverage gaps are.
• Lead performance and load testing for your squad - establishing baselines, identifying throughput and concurrency limits, and surfacing risk before it reaches production.
• Own the squad's Definition of Done quality gate, and act as the final internal check before anything ships to staging or production.
• Mentor QA Engineers in your squad and across the chapter - reviewing their test design, raising the bar on automation quality, and helping them grow into the standards the Chapter
• Deputise for the QA Chapter
• Lead where needed - representing your squad's QA practice in the monthly QA Guild, and contributing directly to chapter-wide standards, tooling decisions, and onboarding material.
• Own a chapter-level initiative - for example, the contract-testing framework, the performance-testing toolkit, or AI-assisted test generation - evaluating, implementing, and documenting it for the whole function.
• Triage the squad's hardest test failures - distinguishing flaky tests from real regressions in complex, high-traffic, or high-risk areas of the system.
