I used to manage a data science team for an ad-tech company. Applied modeling problems come up a lot in advertising - how to model an event as a probability distribution, how to use several of these probability distributions to solve optimization problems in order to get most benefit given a fixed budget, and so on. During my time managing that team, we had a few former PhD's (both graduated and all-but-dissertation). Since you asked, I currently work at Amazon, and we're hiring PhD's as applied scientists: https://www.amazon.jobs/en/search?base_query=phd+mathematics https://www.amazon.jobs/en/search?base_query=phd+mathematics
