When you're talking about a profession though, engineer means something very specific. It means that you're trained and licensed and can be held legally responsible if whatever you're building should malfunction. Referring to your profession as an engineer when you don't meet those criteria is a bit disingenuous. It's akin to the difference between calling yourself a doctor because you went to medical school, and calling yourself a doctor because you got a PhD in english lit.
