By having a math degree you could possibly leverage your knowledge to get into some niche ML areas which still hire well and might turn out to be more interesting. I'd consider physics-informed ML, and time-series modeling. Julia has a good ecosystem for the first one, PyTorch + Pyro are great for the second one.
