Network Systems Engineer Security Clearance

Position: Network Systems Engineer with Security Clearance
100-120k System Administrator (Network-Focused) | TS/SCI Required
Overview
We are seeking a hands-on System Administrator with a strong focus on network operations to support a secure, on-premise lab environment. This role is ideal for someone who has broad IT exposure across networking, systems, and infrastructure, and can operate independently in a cleared environment. The position is primarily Windows-driven but requires working knowledge of Linux systems as well.

Key Responsibilities

• Maintain and administer Cisco-based network infrastructure (routers, switches, and related components)

• Support Windows-heavy environments, including server administration, domain support, and system maintenance

• Manage and maintain virtualized environments using Hyper-V, VMware, and Dell blade server infrastructure

• Perform system administration tasks across both Windows and Linux environments (RHEL/other Linux distributions in lab settings)

• Monitor, maintain, and troubleshoot systems rather than building new pipelines or pushing code into development environments

• Execute and troubleshoot scripts (Power Shell and Bash) for system maintenance, automation, and configuration

• Apply system policies, perform updates, and manage configuration changes in controlled environments

• Support system lifecycle activities including patching, updating, baseline maintenance, and troubleshooting

• Assist with system inventory, configuration tracking, and overall environment stability

• Work independently within a secure, on-premise environment supporting mission-critical operations

Required Qualifications

• Active TS clearance with SCI eligibility (TS/SCI preferred)

• 5+ years of experience in system and/or network administration

• Strong experience with Cisco networking (routing, switching)

• Hands-on experience with Windows Server environments (primary focus)

• Working knowledge of Linux systems (basic administration and troubleshooting)

• Experience with virtualization technologies (Hyper-V, VMware) and server hardware (Dell blades)

• Experience running and troubleshooting scripts (Power Shell and/or Bash)

• Security+ or DoD 8140 baseline certification

• Ability to work independently in a cleared, on-prem environment
Preferred Background

• Prior military experience in IT/communications roles (e.g., 35T, 0671, or similar MOS)

• Experience supporting networks, servers, radios, or communications systems

• Familiarity with Git Lab or similar tools (for maintenance, not development-focused work)

• Broad “jack-of-all-trades” IT background across networking, systems, and infrastructure
Nice to Have

• Experience with patching, STIGs, and secure baseline management

• Experience in air-gapped or classified environments

• Cisco certifications (CCNA or higher)
