Accounts Payable Administrator

About the Company

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 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: Support Groups (global shared-services spanning people, finance, platform, operations, legal, and engagement), Core Groups (developing and owning mission capabilities end-to-end), and Market Groups (applying a regional lens to align capabilities with partner needs across the Americas, EMEA, and Asia-Pacific).

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