Access Control 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.

Required Skills & Qualifications

5+ years of experience in a Systems Administrator, Security Systems Administrator, or Infrastructure Operations role (data

center or critical environment experience preferred).

Strong experience administering Windows Server environments, including troubleshooting, patching, service

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

performance bottlenecks.

Working knowledge of networking fundamentals (IP addressing, VLANs, DNS, routing basics, firewall dependencies, and

troubleshooting workflows).

Strong operational discipline with documentation, change control, and incident response practices.

Strong communication and collaboration skills, especially in cross-functional environments.

Nice to Have

Virtualization experience with VMware vSphere; familiarity with VMware Cloud Foundation is a strong plus.

Storage platform familiarity, especially large-scale video retention and NAS concepts; Dell PowerScale/OneFS or Pure

Storage is a plus.

Scripting/automation experience (Ansible preferred; Python/Powershell also valuable) for operational tasks and

repeatability.

Familiarity with monitoring/alerting practices (health checks, metrics, dashboards, log-based troubleshooting).

Certifications such as Microsoft/VMware, Security+, Network+, or ITIL (helpful but not required).
