The Senior Clinical Data Manager (CDM) will lead data management activities for one or multiple diagnostic product development studies in support of GRAIL’s robust clinical development pipeline. This role is based in Menlo Park, California, and will move to Sunnyvale, California in Fall 2026. It offers a flexible work arrangement, with the ability to work from GRAIL's office or from home.

Our current flexible work arrangement policy requires that a minimum of 40%, or 24 hours, of your total work week be on-site. Your specific schedule, determined in collaboration with your manager, will align with team and business needs and could exceed the 40% requirement for the site. At our Menlo Park campus, Tuesdays and Thursdays are the key days where we encourage on-site presence to engage in events and on-site activities.
