Security Systems Administrator

Fluidstack

9d • $182,000 - $210,000

About The Position

Fluidstack is hiring a Security Systems Administrator to support the physical security systems that protect its AI compute infrastructure. The role helps establish and operate security systems across gigawatt-scale campuses, ensuring buildings meet acceptance criteria before entering support and that deployed systems remain reliable as the estate grows.

The administrator manages remediation queues for cameras, readers, and controllers; conducts firmware and patch campaigns without disrupting video or access control; and leads technical incident response and vendor or integrator break/fix through resolution. The role also improves operational practices by replacing manual inventories and unnecessary onsite work with scalable remote tooling, and by creating repeatable runbooks and standards for every site.

Requirements

• Experience taking systems from a project or vendor team into production support and defining readiness criteria.
• Experience owning a queue against service-level targets, with the ability to describe resolution times and how they were improved.
• Experience replacing an established industry practice with a better approach and explaining the original practice's shortcomings and the benefits of the change.
• Experience supporting a growing estate and changing operational methods to manage that growth rather than simply adding staff.
• Experience running patch and firmware campaigns across a fleet where a failed update could cause a noticeable outage.
• Production administration experience with Windows Server, including Active Directory, certificates, and related tooling.
• Ability to write runbooks for other people to follow, including during off-hours.
• Experience escalating vendor or integrator issues to resolution, with an escalation history to demonstrate the work.

Nice To Haves

• Experience with video management and access control platforms such as Genetec Security Center, Milestone, or Lenel.
• Experience with physical security device fleets, including cameras, readers, and door controllers.
• Experience with enterprise virtualization and clustered storage, including Hyper-V, VMware vSphere, Nutanix, failover clustering, or SMB.
• Experience with scripted remediation using PowerShell.

Responsibilities

• Define and enforce acceptance criteria for buildings entering support.
• Manage remediation queues for cameras, readers, and controllers against service-level response and resolution targets.
• Execute firmware and patch cycles across multiple campuses without taking video or access control offline.
• Lead technical incident response when security systems fail.
• Drive vendor and integrator break/fix issues through to resolution.
• Replace inefficient physical security operations practices, including manual device inventories, unnecessary truck rolls, and documentation that quickly becomes stale.
• Write runbooks and standards that can be applied consistently across sites and support growth without proportional increases in headcount.
