Functional System Administrator Jobs (NOW HIRING)

Security System Administrator
Location: Ashburn, VA
Summary
The Security Systems Administrator is responsible for the day-to-day administration, maintenance, and support of our
global physical security systems and the infrastructure that runs them. This role blends hands-on ownership of
CCTV/VMS, Access Control, and Key Management platforms with core systems administration across Windows Server,
virtualization, networking, and storage.
You will work closely with Security Engineering/Security DevOps, local technicians, and facility stakeholders to keep
systems reliable, secure, and consistently deployed across data centers and edge sites. This is an operations-focused
role with strong technical depth, clear ownership, and high impact.
Key Responsibilities
Administer and support physical security platforms including video management/CCTV (Genetec, Avigilon), access control
(Lenel, Genetec), and key management (Traka).
Maintain and operate the supporting server infrastructure including Windows Server, services, patching, backups,
hardening, and health monitoring.
Perform Tier 2 troubleshooting for incidents impacting security platforms and infrastructure, including log review, root
cause isolation, and coordination of remediation.
Partner with local site technicians on break-fix execution, validating outcomes and restoring service quickly and safely.
Perform basic-to-intermediate network troubleshooting supporting security systems, including VLAN/IP troubleshooting,
routing/firewall dependency identification, and packet-level checks when needed.
Support virtualization operations where security systems are hosted, including VMware/vSphere (and exposure to
VMware Cloud Foundation where applicable).
Support storage operations that enable video retention and system performance, including SMB/NFS fundamentals,
capacity monitoring, and performance troubleshooting (PowerScale/OneFS or Pure Storage experience is a plus).
Execute routine maintenance and lifecycle work such as upgrades, firmware/software updates, certificate renewals (where
applicable), configuration standardization, and vulnerability remediation.
Maintain accurate documentation and operational artifacts including runbooks, diagrams, inventories, and incident/change
records.
Contribute to continuous improvement by identifying recurring issues and proposing fixes through standardization,
automation, or monitoring enhancements.
Provide guidance and support to internal partners (Security, Facilities, DC Operations) on platform capabilities, limitations,
and operational best practices.

management, and operational hardening.
Hands-on experience supporting physical security systems such as VMS/CCTV, access control, and/or key management
platforms (Genetec, Avigilon, Lenel, Traka preferred).
Solid troubleshooting ability across systems and infrastructure layers, including logs, services, connectivity, and
