No, just an ME degree from Stuttgart but I focussed on controls and optics. I worked in machine vision for years and gradually drifted into software and firmware engineering with a lot of EE mixed in. I'm at HP now and they don't car what your degree is in.
Sounds like an interesting career! I'm working as a software engineer on a rail automation project at the moment, finishing my BEng in Mechatronics in mid 2013. May I ask what you work on at HP?
