IE is a very broad field with applications ranging from construction management (think hard hat) to supply chain design and management (think of how hospital supplies get from the supply room to all areas) to budget/productivity/efficiency analyses (what I do for FedEx).
Many universities offer an Engineering Management Masters, so that may be something you wish to consider as well. Many companies will be unwilling to hire a recent graduate straight into management without any previous experience, so it will be wise for you to gain some experience through internships/work-study before you start applying for a full time job.
If you are successful in getting a management type job after your Masters degree, you can probably expect a salary range between $70-$90k.
Hope this helps!
