Erin MacDonald is the founder and lead Product Designer at Between Design. She worked as a Senior Human Factors Engineer in Hardware Tech at Apple; as an Assistant Professor of Mechanical Engineering and Director of the Design Impact Program at Stanford; as a Marketing Researcher at MIT; and as a tent and sleeping bag developer at Sierra Designs. And while her desk there was next to the washing machine in a closet, it is arguably her most treasured of any of these positions.
