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?
100%, but my understanding is that most often applies to fields of engineering outside of computer science like mechanical, chemical, structural engineering etc. But there are licensing bodies for achieving Professional Engineer of FE in some cases for CS.
I am not a lawyer but I presume most laws apply to claims of such certifications rather than job titles. In either case most people don’t pick their own job titles. Just don’t put PE, after your name, same as you should not just randomly throw BSN or MD unless you have a registered licensure.
