• Act as the final escalation point for Tier 3 hardware, software, and network issues
• Lead IT infrastructure upgrades, hardware refreshes, and new technology deployments, including scoping, vendor selection, and implementation
• Own backup, disaster recovery, and business continuity plans, including regular restore testing and documented recovery objectives
• Mentor and provide technical direction to junior systems administrators and helpdesk staff
• Lead the after-hours on-call rotation and coordinate emergency response as needed
