Security Systems Administrator

Role overview Operate and scale support for physical security systems across a growing, multi-site data center estate. You’ll help determine when new buildings are ready for ongoing support, keep device fleets healthy, and improve operations so additional campuses can be supported through better tooling and standards.

Responsibilities - Define and enforce readiness criteria for transferring buildings and systems into production support. - Manage remediation queues for cameras, access readers, and controllers against service targets. - Coordinate firmware and patch campaigns across sites while maintaining video and access availability. - Lead technical incident response and drive vendor or integrator repairs through to resolution. - Improve operations through remote remediation, accurate device inventories, and current documentation. - Write repeatable runbooks and standards for use across sites.

Requirements - Experience taking systems from project or vendor delivery into production support, including setting acceptance criteria. - Ownership of a support queue measured against service targets, with a record of improving resolution times. - Experience supporting a growing systems estate and adapting processes to handle increased scale. - Experience running patch or firmware campaigns where failed changes could cause visible outages. - Production Windows Server administration, including Active Directory and certificates. - Clear, usable runbook writing and experience escalating vendors or integrators to resolve issues.

Nice to have - Experience with video management or access control platforms such as Genetec Security Center, Milestone, or Lenel. - Familiarity with camera, reader, and door-controller fleets; Hyper-V, VMware vSphere, Nutanix, clustered storage, or SMB. - PowerShell scripting for remediation and operational tasks.
