An information technology (IT) director oversees the function and maintenance of technology within an organization. Some companies use the terms Chief Information Officer (CIO) or Chief Technology Officer (CTO) interchangeably with IT director, but in large corporations, these are usually different positions. As an IT director, your duties include supervising IT department employees, developing network policies and procedures, and managing vendor contracts. You also oversee large-scale technology projects, such as upgrading system infrastructure and enhancing network security.
