• Manage IT vendors, licensing, hardware/software inventory, support contracts, and technology lifecycle planning.
• Support cybersecurity, business continuity, disaster recovery, and regulatory compliance initiatives including NIST and CMMC requirements.
• Coordinate IT operations across multiple locations in partnership with local site support personnel.
• Prepare project plans, budgets, cost-benefit analyses, metrics, and status updates for leadership review.
• Participate in after-hours support, maintenance activities, and critical incident response as needed.
• Ensure IT operations comply with company policies, contractual obligations, and applicable regulations.
• Drive continuous improvement, operational standardization, and cost optimization initiatives across the IT environment.

• Proven experience leading enterprise-scale projects impacting multiple business units, including ERP implementations, infrastructure migrations, acquisitions/integrations, or large-scale technology deployments.
• Proven experience leading ERP implementations including business process coordination, data migration, integrations, stakeholder management, and post-go-live operational support.
• Strong experience supporting enterprise infrastructure environments including VMware, Microsoft Azure/M365, Windows Server, and Cisco/Ubiquiti networking technologies.
