Staff Product Security Engineer

• GRAIL is seeking a mission-driven and high-impact Staff Product Security Engineer to serve as a technical cornerstone for product security initiatives across the company. Reporting to the Director of Product Security, this role plays a critical part in enabling secure, resilient products that support GRAIL’s life‑saving mission. As a Staff-level individual contributor, you will lead the technical execution of the Product Security roadmap, partner closely with Engineering and Product teams, and mentor other security engineers. You will influence architecture and development decisions across the product lifecycle, helping teams navigate an evolving threat landscape while maintaining delivery velocity in a regulated environment. This role is based in Menlo Park, California, and will move to Sunnyvale, California in Fall 2026. GRAIL 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 60%, 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 60% requirement for the site.

This Staff-level role is expected to model GRAIL’s core values and LEAD leadership attributes by leading through influence, collaborating across boundaries, driving results with integrity, and continuously improving how product security enables patient impact.

These responsibilities summarize the role’s primary responsibilities and are not an exhaustive list.
