AI Cybersecurity Engineer

Menlo Park, CA Full Time
Our mission is to detect cancer early, when it can be cured. We are working to change the trajectory of cancer mortality and bring stakeholders together to adopt innovative, safe, and effective technologies that can transform cancer care.

We are a healthcare company, pioneering new technologies to advance early cancer detection. We have built a multi-disciplinary organization of scientists, engineers, and physicians and we are using the power of next-generation sequencing (NGS), population-scale clinical studies, and state-of-the-art computer science and data science to overcome one of medicine’s greatest challenges.

GRAIL is headquartered in the bay area of California, with locations in Washington, D.C., North Carolina, and the United Kingdom. It is supported by leading global investors and pharmaceutical, technology, and healthcare companies.

We are looking for a collaborative and forward‑thinking AI Cybersecurity Engineer to help lead the design and implementation of our Cybersecurity Program. In this role, you will work closely with teams across the company to ensure our use of AI—large language models (LLMs), ML pipelines, commercial AI platforms, and AI‑enabled applications—is secure, responsible, and aligned with our organizational values. 

You will also contribute broadly to cloud, application, and platform security initiatives.

You’ll partner with Data Security, Engineering, Architecture, Legal/Compliance, and business stakeholders to ensure our AI adoption is responsible, resilient, and secure by design. 

This is an opportunity to define foundational controls for a rapidly evolving domain. We are looking for you to bring curiosity, a security engineering foundation, and the ability to work with diverse stakeholders.

You will be responsible for detecting, analyzing, and neutralizing sophisticated cyber threats while proactively gathering intelligence to predict future attacks. This is a leadership role requiring a balance of deep technical expertise in defensive operations and the ability to communicate risk to senior leadership and stakeholders.

This role requires more than technical proficiency. We are looking for a leader who models GRAIL’s core values, embodies our LEAD leadership attributes, and delivers results with integrity, inclusivity, and strategic insight.

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 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. 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.
