Job Analysis:

This Network/System Administrator III role is fundamentally about ensuring the secure, reliable, and efficient operation of complex, classified government networks, primarily within Department of Defense Special Access Programs (SAPs). The successful candidate will not only manage day-to-day network operations but also actively architect and enhance the network infrastructure, making strategic technology decisions in line with cybersecurity requirements and evolving mission needs. Critical to this role is the ability to operate independently, leading operations teams with minimal oversight, while navigating the rigor of stringent security protocols (TS/SCI clearance and polygraph) and compliance frameworks such as JSIG and RMF. The job demands a blend of deep technical expertise—covering Windows and Linux servers, virtualization, enterprise networking, security tools (SIEM, ACAS, Nessus), and risk frameworks—and soft skills such as collaborative communication within high-stakes, multi-agency environments. The successful candidate will regularly solve complex, ambiguous problems that impact network confidentiality, integrity, and availability across highly sensitive environments, balancing operational continuity with proactive cybersecurity risk mitigation. Early success will likely be marked by seamless IT operations leadership, improved security posture through tuning event monitoring and incident response, and consistent compliance with mandatory DoD policies and technical standards.
