Wherever we operate, we build vertically integrated full stacks of capability—designing, building, and operating turnkey solutions that let customers scale capacity while benefiting from continuous cycles of innovation. With operators and engineers under one roof, we close the gap between lab and field—what we call connecting design with effect.

Metrea's solutions are built for elegance: effective, efficient, and evolving. This approach enables our partners to do more with less and achieve outsized, asymmetric advantage against rapidly evolving threats. Headquartered in Washington, DC, Metrea has facilities across the United States, the United Kingdom, Europe, and beyond.

In this role, you will serve as a key member of our enterprise IT team, building, maintaining, and securing the network infrastructure that keeps our organization connected and mission-ready across on-premises, cloud, and hybrid environments. You will partner with the Senior Network Engineer, cybersecurity, cloud operations, and IT support teams to deliver resilient, high-performance communications—including classified environments. You will be successful if you thrive in a fast-paced, security-focused setting, take ownership of complex network challenges, and are driven by continuous improvement. This is an excellent opportunity for a hands‐on engineer looking to grow professionally while making a direct impact on the availability, security, and performance of critical network systems.

What You'll Do

  • Design, deploy, and maintain enterprise network infrastructure—routers, switches, firewalls, and wireless access points—across classified and unclassified environments.
  • 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'll 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).
  • Foundational understanding of cloud networking concepts (Azure VNETs, AWS VPCs, security groups, route tables).

Additional Eligibility Qualifications

  • CCNP Enterprise or equivalent advanced networking certification.
  • Experience with defence cybersecurity regulations (NIST 800‐171, CMMC, ISO 27001, ITAR).
  • Hands‐on experience with Software‐Defined Networking (SDN) or SD‐WAN platforms.
