I'm an electrical engineer - electrical designer, really, since in construction an Engineer (capital 'E') has to have a P.E. license and I don't have it. I design lighting, communications, fire alarm, security, and power systems for buildings. And I enjoy it, more so than other jobs I've had. I was previously a project engineer for a towing equipment company and found that boring, and a designer or project engineer (depending on how generous a mood the boss was in that day) for a carpet handling equipment company (very interesting work, crappy company.)
