Sourcing Manager, Contractors & Site Services

About the role

Fluidstack is deploying AI infrastructure at hyperscale pace across multiple sites in multiple states. That buildout depends on a dense, highly-skilled workforce: low voltage electricians, CDU installation and maintenance technicians, facility operations staff, physical security, and dozens of other specialized trades. Keeping that workforce deployed, qualified, and productive requires a sourcing function that builds deep relationships with contractors and tradespeople. As a Sourcing Manager, Contractor Workforce & Site Services, you will own the end-to-end strategy for sourcing, onboarding, and sustaining the human infrastructure that keeps our sites running. This spans contract labor sourcing from regional trade unions and national staffing firms, site amenity and support services procurement (hotels, food, transportation, PPE), contract-to-hire pipeline management in partnership with Recruiting, and workforce development programs that build trades capacity in the communities where we operate. You'll work closely with DC Ops, Construction, and Finance to ensure labor supply keeps pace with our deployment roadmap.
