This is the company’s second major executive announcement in nearly a week, as Northrop Grumman veteran Leif Henecke recently joined ASRC Federal as chief information officer.
Caswell, previously MSE’s president, will be responsible for acquiring new business in targeted markets.
The subsidiary provides custom, integrated systems and software engineering solutions to defense and other government customers.
Knowles previously served as MSE’s senior vice president of operations, where he directed the subsidiary’s technical operation across all areas and service offerings.
Caswell brings experience in defense market sales and Knowles has worked with MSE customers for more than two decades, ASRC Federal President Ken Asbury said in a release.
Before joining the company, Caswell served as president of Computer Sciences Corp.’s (NYSE: CSC) air, missile and national defense business area, having responsibility for profit and loss.
The 15-year executive management veteran has also served in operations and development roles for CSC, the Strategic Defense Initiative Organization/Ballistic Missile Defense Organization and the U.S. Air Force.
Knowles previously held positions in engineering, program management and business development at MSE and helped deliver software engineering and systems integration services for mission systems.
