Yes, yes, Engineer is protected in a lot of spaces. Even here. That said the university programme I've attended was to make me into a "Sotware Engineer" not a "Developer". This university is a university for engineers. Obviously I don't have to requalify every year to remain an Engineer, but saying that I am not an Engineer is factually untrue.

I dont care about names but to be offended because it says Software Engineer on my resume is just dumb.

Also we design a lot of crucial systems. (Such as any RTOS, banking systems and so on and so forth)
