FF3, FF5 and FF12HD (only HD version) all use the Job system.
Then you've got the "Bravely" series aka Final Fantasy 4 Heroes of Light, Bravely Default, Bravely Second and Bravely Default 2 (confusing naming, innit?).
FF7, FF9 and FF10 (with Expert Grid) while not Job System based, all offer substantial amount of customization that make them equally fun in that regard.
Then you've got Octopath Traveler which also uses the Job system, but with a twist as the characters' primary Jobs are fixed in stone but you can give them a second Job simultaneously and you've got complete freedom in that regard.
And then there's Dragon Quest 3, 6, 7 and 9 which also use the Job system.
Recently released Yakuza 7 (or Yakuza: Like a Dragon in the west) uses the Job system as well.
Oh and there's also Final Fantasy Dimensions, which is a mobile game (WAIT, HEAR ME OUT) made by the devs of the 4 Heroes of Light (and the DS remakes of FF3 and FF4) and is a classic SNES-style FF game (no MTX, it's a full proper game, no gacha, no online bs) in style of FF5 and FF6 and uses the Job system as well, I sincerely recommend it.
