Japanese RPG - like Fire Emblem, for example, where once a character reaches a certain level, they can be raised to their advanced class, or like in the MMO, Final Fantasy 14, where the same is true.

A better way of looking at it might be by calling the "job" a "subclass" or "specialization" instead.
