About Us

Pacific Defense, a small fast-growing company that develops and provides advanced multi-function RF systems for the U.S. Department of Defense, is seeking talented engineers and designers to support the development of mission-critical software and systems. As a member of the Pacific Defense group of companies, our growth is accelerating. Pacific Defense designs and builds advanced, military standards-based, modular open systems architecture (MOSA) systems. These systems conform to the Army's C4ISR Modular Open Suite of Standards (CMOSS) and the Air Force's Sensor Open Systems Architecture (SOSA) Standard. These CMOSS /SOSA systems are used for multi-mission electronic warfare, tactical communications, signals intelligence, cyber-EW, high performance computing and often simultaneous operation of these capabilities.
