Network Engineer

Company Overview

Metrea delivers effects-as-a-service to national security partners across five domains and more than a dozen mission areas. These include airborne ISR, electronic warfare, secure communications, aerial refuelling, special air missions, aerial firefighting, and advanced simulation. We own the whole stack: designing, building, and operating turnkey capabilities that give our partners decisive, asymmetric advantage against rapidly evolving threats.

Our operating model is built around three interlocking pillars. The Support Groups provide a global shared-service – spanning people, finance, platform, operations, legal, and engagement. This frees up our Core Groups, who develop and own mission capabilities end-to-end, to focus entirely on delivery. The Market Groups apply a regional lens, ensuring that our agile and adaptable capabilities remain aligned to the wicked problems that matter most to our partners across the Americas, EMEA, and Asia-Pacific.

At the heart of our model is a simple but powerful idea: be a true partner with skin in the game. Our partners need effects, not just equipment. By owning the full stack – from the lab to the field – we are able to drive a continuous cycle of innovation that keeps our partners ahead. It's a fast-moving, intellectually demanding environment where talented people are given real responsibility, work on problems that matter, and contribute to an enterprise that is growing quickly and deliberately.

Headquartered in Washington, DC, with facilities across the United States, the United Kingdom, as well as Continental Europe and Asia-Pacific.

• Configure and optimize LAN, WAN, WLAN, SD-WAN, and VPN solutions using platforms such as Cisco, Aruba, and Palo Alto


• Implement and enforce network security controls including firewall policies, ACLs, IDS/IPS, NAC, and network segmentation aligned with NIST, CMMC, ISO 27001, and Cyber Essentials frameworks


• Support cloud and hybrid network connectivity across AWS and Azure, including VNETs, VPCs, VPN gateways, ExpressRoute, and Direct Connect


• Deploy and manage enterprise wireless networks—access points, controllers, SSID/VLAN configuration, WPA3/802.1X security, and RADIUS integration


• Perform Tier 2/3 troubleshooting, root cause analysis, and incident response to maintain 99.99% network uptime


• Monitor network health and security posture using tools such as SolarWinds, Netwatch, SNMP, NetFlow, Wireshark, and SIEM platforms


• Execute change management activities including firmware upgrades, patch management, VLAN provisioning, and routing updates


• Create and maintain network documentation: runbooks, SOPs, network diagrams, device inventories, and post-incident reports


• Collaborate cross-functionally with Systems Administration, DevOps, Security, and the SOC; coordinate with vendors on hardware/software issues

What You Bring

• 5–8 years of hands-on experience in network engineering or administration supporting multi-site enterprise environments (500+ endpoints)


• Strong command of TCP/IP, OSI model, routing protocols (BGP, OSPF, EIGRP), and switching technologies (VLANs, STP, VxLAN)


• Demonstrated experience with Cisco (Catalyst, Nexus) and/or Aruba enterprise networking platforms


• Working knowledge of Palo Alto firewalls or equivalent enterprise firewall solutions


• Solid understanding of VPN technologies (IPSec, SSL/TLS), DNS, DHCP, IPAM, and core network services


• Experience with network monitoring, logging, and analysis tools (SNMP, NetFlow, syslog, Wireshark)


• Familiarity with wireless networking technologies (802.11ax/Wi-Fi 6, controller-based architectures)
