There are two kinds of job.

* Adjunct lecturer/temporary faculty: These are people hired for just one semester for a specific course, for fairly minimal salary. Ads for these are posted usually 3 to 6 months before the semester starts, and you can just apply to them.

* Visiting faculty: If you are actually really good, sometimes Universities will hire you as a visiting faculty. There is a case-by-case negotiated contract (usually 1 or 2 courses per year, with whatever other constraints you have). The difference from the first choice is that you have some choice in the course you get to teach, and how you teach it.

I would recommend starting from the first choice, and teaching a large standard course where other faculty are around to help you. Teaching well is very difficult (and teaching badly is relatively easy), and people's future is at stake, so its best to start slow and learn the ropes before attempting something difficult.
