> You don't need graduate level math, but if you want to use machine learning it's basically mandatory to have a solid understanding up to calculus, linear algebra, and probability/statistics. At least if you want to understand the underlying algorithms, which in my opinion is essential to being a good data scientist. Key word in that last phrase being good. There are, of course, companies which will take developers with little experience and try to mold them into machine learning experts without much support -- the end result being misguided application of techniques. But hey, it's a job...
