No, he is a governante o gobernador (if he's a goverment official)
No, he would be termed subempleado o subutilizado.
Now, stand back and watch the s**t hit the fan! 
Some positions we completely change words for if the sex of the person doing it changes. The cleaning lady if male would probably be called a janitor. We don't call him the cleaning man. You're asking something akin to what is a male governess? We would use another title if a male held the same position.
