I would agree with everyone else that there is definitely not a requirement for a second language. That said, I have known a few people who have been able to use their knowledge in other languages to help out other teams and really stand out. For instance, if we have contracts that we need to read and understand that are in other languages, we will ask people who know that language to help translate the document so it is understandable for the rest of the team. I would say it's a valuable resource to have.
