Working within established procurement, finance, security, and data center operations policies, this IC3 independently owns a defined work queue; coordinates across requestors, vendors, Accounts Payable, Procurement, Finance, and site teams; and resolves routine-to-complex issues before escalation. Coordinate onboarding and re-onboarding workflows for new and existing vendors, including intake checklists, supplier master-data requests, tax and banking documentation routing, insurance certificates, security and badging prerequisites, site access dependencies, and required operational contacts.
