I'm aware of the derivation of these sorts of titles - this "title inflation" has permeated every aspect of our culture. Custodial engineer "sounds snappier" than janitor, "waste management engineer" sounds snappier than garbageman, Human Resources Administrator sounds snappier than Personnel Manager, etc., etc., etc. ad nauseum....
None of that changes the fact that it's all pretentious puffery... /grin
In away I am sympathetic. I have a lot of folks call me the “Computer guy” or “IT Guy”, belaying that fact that I am actually the IT manager/director and have hard earned degrees and certifications out the a$$. I kind of laugh it off, but my newest green tech is also a “Computer guy”
