Chief Medical Officer

The Opportunity

insitro is a physical AI company dedicated to unlocking causal human biology and accelerating the delivery of better medicines to patients. Our unique Virtual Human™ platform identifies novel, high-impact genetic intervention points, which our TherML™ platform translates into therapeutics—whether small molecules, biologics, or oligos. With programs in key therapeutic areas like MASH, ALS, obesity, and dry AMD advancing toward the clinic, and our first IND submission for MASH slated for the second half of this year, we are at a pivotal inflection point. Since its founding in 2018, insitro has raised approximately $800M from capital raises and discovery partnerships with pharmaceutical companies, including Bristol Myers Squibb and Eli Lilly.

We are seeking an innovative, highly quantitative, and data-driven Chief Medical Officer (CMO) to architect and lead our end-to-end clinical development strategy. This role is paramount to ensuring we fully leverage our AI/ML capabilities to maximize the probability of clinical success and accelerate timelines.

A key success factor in this role will be a proven track record of designing and leading the execution of Phase 1 trials bridging the gap between translational medicine and the clinic and successfully designing and delivering Phase 2 trials, establishing human POC. You will achieve this by leveraging our AI/ML capabilities to architect innovative trial designs that optimize patient selection and dosing from the outset. By imbuing translational thinking into our discovery efforts and working with our discovery teams, you will ensure that the clinical foundations for every program are built from the start to ensure optimal outcomes and rapid development.

In this role, you will report directly to the CEO and be a key member of the executive leadership team. The role is either based in South San Francisco and is expected to be onsite ~3 days a week or hybrid and expected to be on-site for 1-2 weeks per month.
