Metrea Management Limited delivers effects-as-a-service to national security partners across five domains and more than a dozen mission areas—including airborne ISR, electronic warfare, secure communications, aerial refuelling, special mission aviation, aerial firefighting, and advanced simulation.

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.

This role sits within the MAME area of Platform Group IT Engineering. Responsible for the design, deployment, and operational support of IT infrastructure across Metrea's global platforms.

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.
