Here are a couple of CS-y but not too math-y suggestions.

Consumer-facing interactive native apps are typically low on CRUD and some of them require non-obvious solutions. You could try to get a job (or just create a product on your own) on mobile or in games.

Another option is working on tools instead of apps. If you manage to get some non-trivial gcc/clang/kernel patches accepted you can try to find a company that works on those.

(I've worked on Google Maps for Mobile and am now building a robotic waste recycler - no CRUD for me since 2002 unless I've decided to build some for my own needs).
