Mission Network Engineer

Position Summary

The Mission Network Engineer is responsible for maintaining, securing, and evolving complex network environments that support enterprise information systems, remote ISR systems, research and development activities, and mission-specific operations. These environments include physical and virtual infrastructure, Linux-based systems, multiple network paths, secure remote access, overlay networks, layered security controls, and unique communications architectures. The role requires a broad technical foundation across networking, Linux, virtualization, secure communications, systems integration, and special or non-standard communications TTPs, supporting secure connectivity, segmentation, traffic protection, low-signature communications, obfuscation, anonymity, and resiliency techniques in accordance with authorized requirements, applicable policy, export control requirements, access management procedures, and operational‑security standards.

• Design, build, configure, maintain, and troubleshoot complex commercial, classified, controlled, and mission‑specific network environments
• Support network infrastructure for enterprise information systems, remote ISR systems, and distributed operational environments
• Configure and manage routing, switching, firewalls, VPNs, secure remote access, wire‑less networking, virtual networking, Linux networking, and network security appliances
• Implement secure tunneling, remote access, mesh VPN, site‑to‑site VPN, overlay networking, and resilient communications solutions using technologies such as Wire Guard, Net Bird, Tailscale, OpenVPN, IPsec, or equivalent tools
• Develop and maintain secure network architectures that support segmentation, access control, traffic protection, low‑signature communications, obfuscation, monitoring, and operational‑security requirements
• Troubleshoot complex connectivity and performance issues across physical networks, virtual networks, Linux systems, VPNs, cloud services, endpoints, servers, security tools, ISR systems, and mission applications
• Monitor network performance, analyze traffic, conduct packet capture, and provide recommendations for reliability, capacity, security, and quality of service
• Plan and execute network upgrades, expansion, lifecycle management, configuration changes, and technical improvements to support evolving mission and enterprise requirements
• Evaluate, test, and integrate new network technologies, communications tools, open‑source platforms, appliances, and services
• Support network security, compliance, and incident response activities, including firewall policy management, segmentation, logging, IDS/IPS integration, vulnerability remediation, documentation, and audit support
• Create and maintain network diagrams, technical documentation, configuration baselines, standard operating procedures, implementation guides, records, and reports
• Coordinate with systems administrators, cybersecurity teams, vendors, cross‑functional technical teams, and mission stakeholders to resolve issues and support project delivery
• Provide technical guidance to less‑experienced staff as needed

• Bachelor’s degree in Information Technology, Computer Science, Cybersecurity, Network Engineering, Communications Systems, or related discipline. Relevant military, government, or industry experience may be considered in lieu of a degree.
• Minimum 7 years of experience designing, administering, securing, and troubleshooting complex network environments in secure, classified, mission‑critical, operational, or highly technical settings.
• Broad hands‑on knowledge across networking, Linux, virtualization, secure communications, systems integration, and operational infrastructure.
• Strong experience with TCP/IP, routing, switching, VLANs, subnetting, DNS, DHCP, NAT, firewalls, VPNs, wireless networking, secure remote access, Linux networking, and command‑line troubleshooting.
• Experience designing and supporting physical, virtual, cloud, hybrid, distributed, Linux‑based, or mission‑specific network architectures.
• Experience with network, firewall, VPN, and routing technologies such as Cisco, Juniper, Palo Alto, Fortinet,…
