Director of Security

How We Operate

High ownership. Full autonomy.

• Own things end to end often taking on scope outside your core role without being asked to get things done.
• Velocity. We drive everything forward as fast as possible.
• First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
• Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.

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.

What We're Looking For

• 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.

Salary & Benefits

• Competitive total compensation package (salary + equity)
• Retirement or pension plan, in line with local norms
• Health, dental, and vision insurance
• Generous PTO policy, in line with local norms
