Milwaukee companies/jobs related to auto industry?

Hello,

Recently moved to Milwaukee and working at a software company. I am a huge car enthusiast and I am trying to get myself into a career path that has some connection to the auto industry that is not a car dealership/repair shop etc.

Do you happen to know of any companies in the area that work with the auto industry at a higher level? or is this a "move to Michigan" type of reality.

Thanks!
