Managing a hedge fund is a whole business. There are many different positions at a large hedge fund manager. Do you want to be a portfolio manager or securities analyst? An accountant? A trader? A compliance officer? A technologist? A programmer?
I haven't seen many hedge fund jobs posted on websites (I haven't been looking much either, though.) I know a lot of hedge fund people come from mutual fund companies or investment banks. So you might try entering financial services through one of these. Headhunters in NY, Chicago, and Toronto are probably the best resource for hedge fund positions.
