Ironically it took me a while to even start using that terminology. Where I'm from, "engineer" means something specific, even in software, and you can't just call yourself an engineer (well, there's no LAW against it, but people will call bullshit pretty fast if you didn't go through the right channels). In the US, everyone's an engineer. Im surprised the person who serves me my burger at the counter isn't a Bovine Product Assembly Engineer.
