This is maybe not the answer you want to hear. Outside of academia, there are not a lot of places that will hire you to do pure math. Most companies need the math to be applied to some product/strategy for revenue purposes. If your math has no application, then why would a company pay you for it. That being said, fields such as data science and machine learning (both applied) are pretty hot right now.
A little further remark, I'm not actually opposed to applying math (or e.g. some kind of logical modeling), just to the "traditional" applied math subjects, i.e. numerical computing or statistics.
