Senior Software Engineer; Frontend focused

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.

This role sits within the Digital and Synthetic area of Metrea. 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.
