Full Job Description
Role Scope
  • Own Fluidstack's global physical security program end to end: standards, policies, roadmap, and execution across a growing multi-site, multi-jurisdiction portfolio.
  • Architect and govern ESS, ACS, and VMS deployments across greenfield builds and operational sites.
  • Lead the GSOC buildout and partner with the cyber-physical and detection engineering functions.
  • Partner with construction and site teams on security requirements from pre-RFS through operations, and manage guard force vendors, systems integrators, and technology vendors, including MSA/SOW negotiation and performance governance.
  • Own physical security control evidence for SOC 2, ISO 27001, FedRAMP, and customer security schedules, and interface with customer security teams during audits, site inspections, and due diligence.
  • Conduct site assessments, threat and vulnerability reviews, and drive remediation. This is a leadership role with real hands-on work as you build the program: deployment support, vendor walk-throughs, resolving an alert, checking the video.

What We're Looking For

The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • You've built or run physical security programs for data centers, critical infrastructure, or large-scale industrial facilities, and you know what good looks like at scale.
  • You've stood a program up from early stage and owned both data center and corporate spaces.
  • You understand cyber-physical convergence deeply. This is more than gates, guards, and guns.
  • You have deep hands-on expertise with enterprise ESS, ACS, and VMS platforms (Lenel, Software House, Genetec, Milestone, Avigilon, or equivalents), and you can read and contribute to security design drawings and construction documents.
  • You've managed guard force vendors and systems integrators across multi-site environments with strong contract governance, and you know GSOC operations: alarm management, tooling integration, and escalation.
  • You communicate clearly and concisely with executive leadership and customer security teams, and you'll travel 30 to 40% to Fluidstack offices and sites.
  • Bonus: AI data center infrastructure. CPP, PSP, or CISSP. Threat, vulnerability, and risk assessments. Commissioning experience.
