I went to school for electronics engineering, and never got a job related to the industry lol....I am currently a test technology engineer, and I do dyno testing (engine and chassis) for outside customers, as well as internal r&d for our own emissions reduction systemns in a lab that is epa certified. Sometimes I also do calibration work for engines that do not pass epa standards for the usa. I have also built a few test cells here. Other then that I do performance dyno tuning as a second job which keeps me pretty busy..
