Julie leads the Machine Learning Infrastructure at Netflix, with the goal of scaling Data Science while increasing innovation. She previously built streaming infrastructure behind the "play" button while Netflix was transitioning from domestic DVD-by-mail service to international streaming service.

Julie also co-founded Order of Magnitude Labs, with a mission to build AI capable of doing things that humans find easy and today’s machines find hard: exploration, communication, creativity and accomplishing long-range goals. Early in her career, Julie developed data processing software at Lawrence Livermore National Laboratory that enabled scientists to study the newly-sequenced human genome.
