Definitely yes. I worked in teams with 25 different nationalities and I loved it. Even every-day-stuff like buying groceries is possible without a single german word. Dealing with german authorities (immigration!) might not that easy, though (means long waiting times as they are short on english-speaking staff). Pro tip: if possible wait until april before moving to Berlin, winter is dark and cold ;).
