The QA Automation Testing Engineer owns product quality through an automation‑first approach. This role is responsible for translating product and technical requirements into scalable automation strategies, designing and maintaining robust automated test suites for critical user flows and APIs, and integrating those suites into CI/CD pipelines to deliver fast, reliable signals on release readiness.

Automation is the primary lever for quality in this role. Manual and exploratory testing are performed selectively and intentionally, only where automation is not practical or where additional insight is required. In close partnership with engineering and product teams, the Automation Testing Engineer continuously improves automation coverage, reliability, and execution efficiency to enable predictable, high‑quality releases.
