Site Security Lead — Own End-to-End AI Infrastructure Security

Fluidstack; Abernathy (TX); On-site; USD 212,000 - 258,000; Full time

Job summary

Fluidstack is seeking a seasoned Security Lead to own the on-site security posture across our data center footprint. You will manage guard forces, access control, camera systems, and incident response from first notification to resolution, coordinating with internal teams and vendors.

The role demands hands-on leadership, a track record of securing high-security sites, and the ability to enforce policy while driving improvements that protect critical frontier compute infrastructure.

Qualifications

• You've led site-level security at a data center, critical infrastructure facility, or other high-security site, owning the posture rather than executing a single function within it.
• You've been the go-to escalation point for a facility, the person other teams call first when something security-relevant goes wrong, regardless of which team actually owns the fix.
• You've held guard, access control, and camera vendors accountable to policy and SLA from a leadership seat, without needing to run their day-to-day operations yourself.
• You've driven a security incident to resolution at the site level, coordinating across internal teams and external vendors rather than handling it alone.

Responsibilities

• Own accountability for every security system, process, and policy at your site, serving as the single leader responsible for its overall security posture.
• Act as the on-site escalation point for any issue in which security is a stakeholder, whether it originates in physical security, IT, construction, operations, or a customer-facing concern.
• Ensure the guard force, access control, and camera systems on-site are operating as designed, holding contracted vendors accountable to policy and SLA without running their shift-level operations yourself.
• Drive incident response at the site from first notification through resolution and after-action reporting, pulling in the right internal teams and vendors as the situation demands.
• Enforce site security policy and standards, identifying gaps between what's documented and what's actually happening on the ground, and driving corrective action to close them.
• Represent security in site-level planning and decision-making, ensuring security requirements are accounted for in construction, deployment, and operational changes at your site.
