Support release-level validation by ensuring automated tests reflect actual release scope, dependencies, integrations, and business workflows.
-
Participate in release readiness activities by providing clear test results, risk indicators, defect analysis, and quality recommendations.
-
Support planned production releases and critical off-hours deployments as needed, in alignment with team release schedules.
Troubleshooting & Production Validation
-
Investigate complex application, automation, data, integration, and environment issues.
-
Use logs, metrics, traces, monitoring tools, and application telemetry to troubleshoot failures and improve test coverage.
-
Partner with Engineering, DevOps, QA, and business teams to diagnose defects and validate fixes.
-
Contribute to root cause analysis and identify opportunities to prevent similar issues in future releases.
-
Validate application behavior under realistic conditions, including dependency failures, latency, service degradation, and recovery scenarios.
Collaboration, Coaching & Quality Ownership
-
Work with business and technical stakeholders to understand requirements and ensure functional and technical validation is built into the delivery process.
-
Review requirements, designs, user stories, acceptance criteria, and technical changes to identify testing needs and quality risks.
-
Coach and mentor QA engineers, SDETs, and development teams on test automation, testability, framework usage, and quality engineering practices.
-
Promote engineering practices that make applications more testable, observable, reliable, and maintainable.
-
Proactively identify automation gaps, process improvements, quality risks, and opportunities to improve delivery outcomes.
-
Maintain strong responsiveness and dependability when supporting team needs, stakeholder questions, release validation, and urgent quality issues.
Requirements:
-
Minimum seven (7)+ years of experience in software testing, test automation, software development, or quality engineering.
