The U.S. Army Corps of Engineers (USACE) is one of the world's premier public engineering, design, and construction management agencies. We serve the American people, striving to provide the most effective engineering and environmental science solutions to the nation's complex problems affecting national security, the economy, and the environment in which we live. USACE manages four program areas that include civil works, military construction, real estate, and research and development. USACE is a key player in all aspects of coastal/water resources engineering, construction, flood control, navigation, disaster response, and military construction activities. In support of other programs, we hire large numbers of environmental science professionals, biologists, physical scientists, geologists, hydrologists, and others.
