About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

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.
