Software engineer/developer/programmers may work in one major industry or in a vast array of different industries. Some may work for companies that produce and sell exactly what they work with. Many others work in other types of industries that do not sell these products but make use of their own. So, one could work for Microsoft designing computer programs to sell, while another may work for a large business and be responsible for designing the private computer programs that employees use within their office.
