About the Company

3Play Media is a rapidly growing, profitable start-up making a huge impact on the way people consume online media. We provide premium captioning, transcription, and translation solutions to over 2,000 higher ed, enterprise, media, and government customers. In addition to clear benefits to accessibility of online content to a more diverse audience, we pride ourselves in innovating in the space of online media such as with our interactive transcript plugin. We have been successfully simplifying the typical transcription workflow through flexible APIs, a secure online account system, and integrations with a multitude of players, platforms, and lecture capture systems since we got our start in 2007 out of MIT Sloan, and are eagerly expanding into new markets including medical transcription and audio description for textualizing visual content in multimedia files.

Work Environment

We love our company culture! We are currently a small team of seven developers working closely with each other and with others in the office, with no interest in drama or office politics. We have a spacious office with lots of natural light, a game room with beer and kombucha on tap, and a friendly dog named Bo who shares our views and ambitions (but not our interest in math jokes or riddles — no one’s perfect!). We’ve all made good friends within 3Play, and also enjoy 3Play hosted events including summer retreats and game nights.


Boston, MA – Fort Point on the Red Line near South Station, in the heart of Boston’s thriving Innovation District at the Boston Seaport. Surrounded by Boston’s buzzing tech scene, we are minutes from food truck hotspots, Chinatown, and Downtown Crossing, and new restaurants and bars are popping up regularly next to older favorites.
