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.</p> <p>Headquartered in Washington, DC, with facilities across the United States, the United Kingdom, as well as Continental Europe and Asia-Pacific.</p></div><h3><strong>Group Overview</strong></h3> <p>Electromagnetic and Cyber Group (EM&C) is responsible for developing flexible and survivable advanced electronic warfare and secure communications equipment while providing the industry’s leading signals intelligence, electronic warfare, and cyber experts.
