• Designing and maintaining testing systems for deterministic logic and AI influenced, non deterministic behavior, integrating these validations directly into CI, release pipelines, and review workflows • Engaging early with engineering to surface risks before implementation, strengthening team wide quality skills, and promoting testability as a core design requirement • Broadening our verification approach beyond unit tests into integration, system, stress, and full workflow testing across the entire stack • Maintaining dependable test environments with strong instrumentation for rapid diagnosis, enhancing observability and logging to shorten the path from failure to root cause • Building tools, fixtures, and supporting libraries that generate stable and repeatable test conditions, enabling reliable validation of complex scenarios without ad hoc data creation
