• Coordinate with application teams and vendors (scheduling, validation, infrastructure-level issue triage)
• Provide support to infrastructure-related application services where required (e.g. printing, SFTP, PKI) in the context of platform upgrades
• Perform validation, troubleshooting, and rollback
• Raise and present change requests to the Change Advisory Board
• Produce high-quality runbooks, knowledge base articles, and operational handover documentation
