The reason these posts aren't being filled is that they're almost exclusively looking for AI researchers with postgraduate degrees. Admittedly, knowing the underlying math is incredibly useful if you're focusing on the core functionality of a library or trying to eke out that last bit of precision, but for a ton of applications, having some number sense and an understanding of core statistical/linear algebra principles is more than sufficient (i.e. you don't have to know how to solve by hand, just have an idea of what the numbers are supposed to look like and be able to tell when something's not right). You don't need a postgrad degree to do this, or even a Bachelor's (though you might have trouble convincing a company of this since they seem to be looking for PhDs). I expect that as need increases and more people of varying levels of education start messing with ML for their own projects, the system will move towards certifications, analogous to the cybersecurity industry.
