I have a BS in computer science. I worked at Google for four years. I would guess that your credentials—with a BS in math—would be no bar to getting a programming job. I would focus on direct programming experience instead of further credentialling. Graduate degrees in computer science are generally not required, and not necessarily even useful, for programming jobs in industry. Masters degrees in computer science are especially suspect, because they are often less rigorous than undergraduate degrees in the field. This is especially true of coursework (non-research-oriented) masters degrees.
