Ample Labs is a non-profit committed to using technology to empower individuals facing homelessness in Toronto, Canada. Our work started with broad research showing that even when experiencing homelessness, most people rely heavily on smartphones to find vital information.

Since then, our team has grown to include a dedicated and diverse group of designers, developers, researchers, consultants, public servants, and community members—all united by a common commitment to using tech for social good. Our first digital product, Chalmers, is a web-based chatbot that helps you find local services like free meals offered at shelters or drop-in programs based on your specific real-time location and needs.

Head over to www.chalmers.app to give Chalmers a try!

We are looking for a full-time Full-Stack Developer to join our team to help continue to make Chalmers the world’s smartest, most empathetic chatbot. You will be in charge of developing our second product and helping us scale Chalmers. If you’re interested in creating social impact while you write code and think about the future of AI, chatbots, and social services then this job is for you.
