Some questions about working for a brewery

Hey all,

I'm currently an undergraduate, but I'm looking around at potential careers that don't necessarily fall under the purview of what I'm studying. Have any of you ever worked for a brewery in some capacity, or know what kinds of jobs/pay are hypothetically available? I love beer and I've made enough homebrew (using homegrown hops, even) that I think I might be of some sort of use to a brewing company one of these days, and I would love to know what kinds of things I could do to turn my knowledge into a marketable skill.
