I'm with you. I really like solving problems or finding a good algorithm to solve the problem. What I can say for you is try to find a company with lots of R&D going. I think there are many companies out there, especially startups that are having some R&D to improve their product and beat their competition. I think startups like Prismatic (http://getprismatic.com) and Diffbot (http://www.diffbot.com) have a heavy NLP and machine learning research going in the background to improve their product. I'm interested in joining those companies I mentioned and contribute to their reaserch and development.

I think game companies also have an R&D to improve their AI, path finding, rendering algorithms, etc.

That's it. Just find an R&D job.
