Just... just some jobs.

Knight
Knights are charged with protecting the kingdom and the people within.

Adventurer
Adventurers wander around, doing tasks and killing monsters for money.

Farmer
Farmers work on farms (duh). It's up to you if it's a plant farmer, a dairy farmer, a wool farmer, or whatever.

Baker
Bakers make treats for us to eat, yum yum!

Butcher
Don't know who will take this job, cause it's basically slaughtering animals.

Servant
Servants actually have a good life; they live in the castle with their own rooms, and the royals treat them well, making sure they don't overwork themselves, get sick, or get too little to eat or drink.

Hunter
Hunters hunt and kill different creatures, handing the dead bodies to butchers.

Let me know if you have any suggestions for other jobs!
