In many of the Lord British Ultima computer games, Tinker was a character class. The Tinker class embodied the virtue of Sacrifice your avatar had to attain in Ultima IV. In Ultima IV's land of Sosaria, the Tinker city was called Minoc and you could pick up a Tinker character named Julia there.

The Tinker class was basically a warrior class that could not wear magical chain or magical plate armor but could use all weapons. The Tinker class had some light magic using ability, although not as much as the Ranger or Paladin classes.
