• Implementing and managing network security controls, including IDS/IPS and NextGen firewalls

• Monitoring network performance, capacity, and availability across distributed systems

• Troubleshooting connectivity issues and resolving complex network problems

• Supporting network operating system installation, upgrades, and patching

• Developing and maintaining network backup and recovery procedures

• Identifying and mitigating network vulnerabilities to enhance system security

• Supporting virtualized network environments, including VMware-based infrastructure

• Collaborating with system administrators, engineers, and security teams to support mission needs

Qualifications

• All positions require an active TS/SCI with polygraph

• Experience with network engineering concepts, including routing, switching, and network security

• Experience with technologies such as Cisco IOS, PAN-OS, or similar platforms

• Familiarity with network segmentation, virtualization, and traffic management concepts

• Strong troubleshooting skills across network infrastructure and connectivity issues

• Experience working in fast-paced, operational environments

• A degree in Network Engineering, Information Technology, or a related field (or equivalent experience)

Nice to Have

• Active DoD IAT Level II or III certification (e.g., Security+, CISSP, CASP+, CCNP Security)

• Active Cisco certification (e.g., CCNA, CCNP)

• Experience with VMware/ESXi or virtualized network environments

• Familiarity with intrusion detection/prevention systems and network monitoring tools

• Exposure to network security, vulnerability analysis, or defensive cyber operations

• Military cyber training (e.g., JCAC, UCT, NWBC/INWT)
