Profile match
CACI International is an American technology company founded in 1962 that works almost entirely for United States defence, intelligence and federal civilian agencies. It has moved from being a conventional IT services contractor toward supplying its own technology, with a substantial expeditionary electronic warfare and signals intelligence product line, photonics and optical communications for space, and secure network modernisation. Headquartered in Reston, Virginia, the company employs more than twenty thousand people, the majority holding security clearances, and has grown through a steady programme of acquisitions that add differentiated technology rather than headcount alone.
