Web developer who studied machine learning in grad school (MS) wants to get back into it. How?

I studied machine learning while I was getting my MS in electrical engineering (graduated 2010). Ever since, however, I've been a PHP/MySQL web developer. Needless to say, I haven't used what I learned in college at all, except for an instance when I had a chance to write an insignificant product recommendation engine as a pet project at work.

I'm wondering how I can get my foot into a decent company that will allow me work with large and cool data sets and software like Hadoop. Obviously, I'm not looking to be a data scientist at this time; rather, I want to go back into this field because I'm bored with web development (or specifically the platform I develop for, rather).

I've done a lot of practical data processing in the past, although it's been several years, and have written predictive models in class environments. Where should I start looking? What terms or titles should I search for? Search terms like "machine learning", "big data", etc. yields opportunities I'm not qualified for.
