- Integrate automated testing into CI/CD pipelines and agentic development workflows
- Review and validate code quality, system behavior, and production readiness
- Identify edge cases and failure modes that may be overlooked during development
- Investigate test and production failures, determine root causes, and drive issues through resolution
- Shift quality practices upstream to help engineers and AI agents produce more reliable work
