Zite – Vancouver or San Francisco
We just launched a personalized reader app for the iPad that made a big splash (100k downloads in 5 days).  We do hardcore machine learning and large scale data processing.
We've got positions open for the backend/ML side of things, as well as the iOS/web side.  Looking for contract designers, as well.
