Zite (<a href="http://zite.com" >) is a company with machine learning and data at its core: our goal is to use deep personalization technology to give people news they wouldn't be able to find any other way. We're looking for engineers eager to dig into big data, both on the scalability front and on relevance. We think that personalization technology should be used for more than optimizing your google queries—it should instead be at the core of a product (think Pandora).
