"Engineer" is derived from "ingeniator." Had to look that up.
To change it is, at best, a temporary fix. "Used Car" became "Previously Owned" and "Personnel" became "Human Resources." These will go by the boards because of how humans are.
In my experience, the modifier is used (electrical, mechanical, chemical, etc.) to show an actual, degreed engineer and the rest of the time "engineer" is used, it's just for effect.
