Senior DevOps Engineer

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.

Our Firmware

At Metrea, our single core value is Rooted in Humility, and our four cornerstone attributes are 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.
