Signal Messenger

Privacy is possible. Signal Messenger makes it easy. At Signal, our goal is to develop open source privacy technology that protects privacy rights, promotes free expression and enables secure global communication. We believe that private messaging should be simple and ubiquitous. Signal combines state-of-the-art security and end-to-end encryption with the features that users expect in a modern messaging application. Millions of people use Signal every day to speak freely, and a growing list of organizations have integrated the open source Signal Protocol into messaging platforms that support billions of users. Working on Signal is an opportunity to become part of a diverse group of people who are passionate about privacy. As a nonprofit organization, Signal Messenger is uniquely positioned to focus on its mission in an environment where users will always come first. Our team is growing quickly, and we encourage candidates from a diverse set of backgrounds to apply. workwithus@signal.org
