Job description

Company Overview

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 refueling, 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.

Our operating model is built around three interlocking pillars. The Support Groups provide a global shared-service - spanning people, finance, platform, operations, legal, and engagement. This frees up our Core Groups, who develop and own mission capabilities end-to-end, to focus entirely on delivery. The Market Groups apply a regional lens, ensuring that our agile and adaptable capabilities remain aligned to the wicked problems that matter most to our partners 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. Our partners need effects, not just equipment. By owning the full stack - from the lab to the field - we are able to drive a continuous cycle of innovation that keeps our partners ahead. It's a fast-moving, intellectually demanding environment where talented people are given real responsibility, work on problems that matter, and contribute to an enterprise that is growing quickly and deliberately.

Headquartered in Washington, DC, with facilities across the United States, the United Kingdom, as well as Continental Europe and Asia-Pacific.

Group Overview

Electromagnetic and Cyber Group (EM&C) is responsible for developing flexible and survivable advanced electronic warfare and secure communications equipment while providing the industry's leading signals intelligence, electronic warfare, and cyber experts. Metrea specialises in signal classification, direction finding, advanced geolocation techniques, and waveform development including waveforms for MANET and LPI/LPD applications. Metrea also develops special purpose radios for government customers and licenses DF and geolocation solutions to multiple OEMs.

The Expeditionary Operations Lab, or EXOLAB, focuses on the rapid development, integration, evaluation and delivery of expeditionary capabilities within the Electromagnetic Warfare and Cyber domain. EXOLAB works across research and development, experimentation, prototyping, systems integration, trials and operational delivery. The team addresses complex customer problems by combining existing technologies, emerging capabilities and internally developed solutions into deployable systems. The lab operates across airborne, land, maritime and dismounted environments, with a strong emphasis on practical engineering, rapid learning and delivering systems that are operationally relevant, supportable and resilient.

Position Summary

We are seeking a Principal RF Engineer to lead and support the research, design, development, integration and delivery of radio-frequency systems for expeditionary Electronic Warfare, signals intelligence, spectrum operations and secure communications capabilities.

The role will be responsible for the RF engineering aspects of prototype and operational systems, including RF architecture, receiver and transmitter chains, antenna systems
