It might surprise you that you don't have to have a computer science degree to work in IT. Software and database developers today build very complex systems out of pieces of code that are already written. The abstract reasoning and representation skills you develop while studying math is good training for this type of work. Recent graduates working in this area went to jobs at Amazon, General Motors (automotive), Epic Systems (healthcare IT), Kohl’s (retailer), Northwestern Mutual (insurance), among other companies.
