Counsel / Senior Counsel

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 multiple programs in metabolic disease and neuroscience advancing toward the clinic, and our first CTA/IND submission slated for the second half of this year, we are at a pivotal inflection point. We are seeking a pragmatic, high-output attorney to join our Legal team as Counsel or Senior Counsel, with level set by experience. You will be the daily legal partner to research, lab and technical operations, IT, procurement, finance, and HR, covering commercial and operational matters, compute and infrastructure. This is a high-volume role on a small team: you will own your matters end to end, build and enhance the templates and processes the company runs on, and have an opportunity to grow your scope as insitro grows. You will also be practicing at the frontier of two fields that are both moving fast, drug discovery and artificial intelligence, often on questions that have no settled answer yet. The Legal department here is small, senior, and low-ego, with a genuine seat at the table: scientists, engineers, and the management team come to us early rather than at the end. We are building the function itself, including how AI reshapes legal work, so you will have real influence over the tooling, templates, and processes insitro uses for years. Based in South San Francisco, this position reports directly to the Associate General Counsel and offers an in-person hybrid schedule of three days per week.
