CyberSecurity/SysAdmin

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.

The Support Groups provide a global shared‑service spanning people, finance, platform, operations, legal, and engagement. The Core Groups develop and own mission capabilities end‑to‑end, while the Market Groups apply a regional lens to ensure our agile capabilities align with partner needs 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.

Just like technical firmware connects software and hardware, our Firmware is the constant interface between our mission and our people. Our firmware creates a web‑like, hyper‑collaborative, dynamically hierarchical way of working that helps us adapt quickly, communicate openly, and distribute decision‑making to where expertise actually lives. It enables groups to self‑organize around hard problems, shift fluidly as priorities evolve, and operate with the trust, curiosity, and discipline required in a complex mission space. This foundation allows us to deliver elegant, effective solutions and uphold our purpose: protecting our precious inheritance.
