Full Stack Software Engineer, Lab Platform (LIMS)

insitro is a physical AI company dedicated to unlocking causal human biology and accelerating the delivery of better medicines to patients. Its Lab Platform is a software layer that ties together scientific, automation, and machine learning platforms. It is built as an agentic workflow system that lets scientists drive the lab through an agent, with the goals that everything in the lab is agentically accessible, agentically legible, and humanly verifiable. The role reports directly to the Senior Manager, Software Engineering, and offers an in-person hybrid schedule of three days per week in South San Francisco.
