Principal Radio Frequency Engineer

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. Its 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.
