Defense and Space Manufacturing Vienna, Virginia 501–1,000 employees Founded 1969 Privately Held

ENSCO is a $190M+ defense and aerospace systems integrator with 750+ employees, deeply embedded in U.S. space and national security programs. The company's tech stack—IBM DOORS, Jama Connect, DO-178C, VxWorks, and real-time OS tooling—reflects mature DO-254/DO-178C compliance workflows typical of flight-critical and military avionics work. Active hiring is heavily weighted toward senior and mid-level engineers (36 of 47 roles), with projects spanning milsatcom systems engineering, space force satellite acquisition, and next-gen space communications, indicating sustained government contract wins but also internal strain around integration complexity and requirement management.
