In your opinion what’s the difference between the two? In my opinion both terms are frequently used interchangeably in the workplace.
But I’d like to consider myself as an engineer, because although I don’t consider myself to be good at it, I think I cares about the software that I worked on, its interaction with other services, the big picture, and different kinds of small optimizations.
I mean, what is even engineering?
This is exactly what I mean with “this depends on the country you live in”. Different countries have vastly different regulatory requirements. Taking UK as an example, you can call yourself civil engineer all day long without having to worry any legal consequences because there simply is no such thing as a licensing system for engineers.
Britain’s Engineering Council disagrees.

Well idk the details in that specific case, this was just the first example I found. My point is, that different countries, states and institutions disagree on this matter. There is no universal rule that defines what you need to have achieved to call yourself an engineer.
