• Assist with maintaining AWX job templates, inventories, variables, credentials, procedures, and related documentation.
• Use existing automation and develop scripts or process improvements to improve patching efficiency, validation, reporting, and operational support.
• Maintain accurate system records, patching documentation, procedures, runbooks, and operational reports.
• Follow approved change-management, incident-management, security, and configuration-management processes.
• Participate in scheduled maintenance activities, incident response, and other operational support activities as required.
• Participate in a rotating on-call schedule, if assigned.
