Amazon Cambridge Office

I'm about to start an internship at Amazon in Cambridge, and curious if anyone knows that office or the team I'll be on; I was told I'm working on the "Dig Prod Mgmt - BS - 7120 - BOS" team (illuminating I know), that describes itself as "building the machine learning platform behind Amazon Alexa, Cloud Cam/Key, Echo look, and other Amazon products and services." Anyone have any familiarity with office or team? Thanks!
