Less cheeky answer:
What do you bring to the company? Number crunching is usually done by people who specialized in the kind of math that meets their application. When you specialize to this level in a broad field like math, your best bet is to do research in the field and discover new math. (I'm not denigrating people who choose to do that, btw).
If you wanted a job where someone pays you to crunch numbers all day, you should have gotten an engineering degree.
