4 KudoZ points awarded for this answer. Comment: "Thank you so much to everyone who has left comments and posted discussion entries, all you did really helped out immensely. The translation was actually Greek > Portuguese, but I suspect my question wouldn't have had the same effect if I had used the Greek/Portuguese combination for this, as most people speak English, rather than Portuguese (which means more help for me!). I ended up adopting simply "engineer" (in Portuguese, though), since it gives off the same ring to it as Greek does, and also because I prefer to follow the original. The translation involving the Engineer-Civil Engineer discussion is not THAT crucial for this case specifically because the document was more of a general guideline that should be followed in order for (instructing) someone to write up a power of attorney (it wasn't a power of attorney per se). Nonetheless, I thank you all again for your wonderful input. Each side of the discussion had very good arguments and I sure appreciated them all. Σας ευχαριστώ πάρα πολύ, παιδιά. :-)"
