I am a mechanical engineer. The pay is pretty decent but I have too much college debt to really enjoy it. I work for a major diesel engine company but I work in the alternative fuels program, mostly with natural gas engines. The stuff going on around me is fascinating but what I actually do for a paycheck is pretty lame. It sounded a lot cooler in the interview. I'm supposed to develop spark plugs for these natural gas engines (5.9L-91L engines) and I was told I'd get to do testing and help with design work but what I really do is babysit suppliers and make powerpoint presentations and excel spreadsheets all day.
