Investigate and resolve integration and stability issues between system components and software releases.
Collaborate with Dev, DevOps, and Automation teams to ensure the health and reliability of CI pipelines and test environments.
Analyze and correlate logs from multiple systems (e.g., Jenkins, Kubernetes, syslog, SNMP, or network captures).
Contribute to test planning and validation activities for new network or feature deployments.
Maintain high operational uptime of CI/Nightly test environments by identifying and mitigating recurring issues.
Provide mentorship and guidance to QA engineers on debugging techniques, Linux diagnostics, and test environment maintenance.
Optional: assist with minor scripting (Python/Bash) for log analysis, setup verification, or test monitoring.
