Jobs at the DoD include a wide variety of positions. The Department of Defense hires outside contractors for a wide variety of tasks, so you may be asked to develop software, design military equipment, conduct data analysis, or use software to manage a customer account. This job category refers specifically to civilian roles with the Department of Defense, not military or government positions. Many civilians work for the DoD through an existing agency, but the department also hands out so many contracts that it's possible to be self-employed or even start your own company while lobbying for contracts. Engineering, IT, and intelligence are particularly popular choices, but these are not your only options.
