Computational Engineer (Electromagnetics)

Company Overview Metrea 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 refueling, 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.

Group Overview

The Digital and Synthetic Capability Unit (D&S) is committed to providing mission-driven information solutions that seamlessly bridge the digital and physical realms. Leveraging cutting-edge technologies and advanced platforms, we empower operational readiness and elevate situational awareness across diverse domains—including air, maritime, and space.

Our Firmware

At Metrea, our single core value, Rooted in Humility, and our four cornerstone attributes—Entrepreneurial, Systematic, Discerning, and Over-Deliver. These form what we call our Teammate Firmware. Just like technical firmware connects software and hardware, our Firmware is the constant interface between our mission and our people. It defines how we show up, how we work together, and how we solve complex problems.

Our team 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.
