Job Description Job Description System Risk & Safety Lead South San Francisco, California, USA About Zipline Do you want to change the world? Zipline is on a mission to transform the way goods move. Our aim is to solve the world's most urgent and complex access challenges by building, manufacturing and operating the first instant delivery and logistics system that serves all humans equally, wherever they are.
