Well, my first thought was Weaver, given that the UTM (IIRC) doesn't let you cast magic directly but lets you understand and make working magic systems. You'd have to weave the magic into a form to use.
My next thought was Lego based, a Builder given the above. (I'll admit, the Lego Move did influence that one.)
Then I thought more along the weaving line and thought Wefter, after the warp and weft of a fabric. See http://en.wikipedia.org/wiki/Weft]Wikipedia page for Weft.
