> Engineers have the technical skills to look into basic financial and budgeting, and there are financial planning guys involved in big projects to do the really in depth stuff if required.

If by "technical skills" you mean "being able do to math", you're as far away from finance as "pressing keys on the keyboard" is from "coding".

You don't need a degree to be an engineer, and you don't need a degree to be in "management". But that's not the point.
