This is probably the best resource of its kind I have seen on the web. Here you will find profiles of mathematicians and their jobs, salary ranges, and advice on how to prepare for your own career. If you prefer the same information but on a torus with fancy graphics and Quicktime movies, I have a CD-ROM you can borrow. They have also compiled a list of employers.
