Please do not lock Jobs to the Weapon Class that unlocks them.

Why do you keep using Class and Weapon as if they are two different things?

Anyway if thats how you want it thats fine.

How I'd prefer it is

You Equip your weapon and are identified as being a user of that weapon.

When you level your weapon skill up to the appropriate rank you learn to specialize in a specialized role.

This role is given a name and called your Job (Job and Role are synonyms after all.)

Once you master this Role/Job you are now able to equip any weapon you want and perform the same role as long as your skill with said new weapon is on part with the requirements of the Role.

Wow... I'm not sure how much simpler I can make it for you. Gimme a second to think about it, my GF is a preschool teacher I'm gonna give her a call real quick.
