Job Description

Scientist II, Protein Sciences THE OPPORTUNITY The unprecedented convergence of multi-modal data, advanced disease modeling, and computational power is revolutionizing drug discovery. insitro is harnessing this moment to redefine how medicines are developed for complex diseases. Our AI/ML-enabled platforms integrate and scale data to rapidly discover novel biological insights, allowing us to identify new targets and drugs for neurological, ophthalmological, and metabolic indications. To enable this vision, we are seeking a Scientist II to join our Protein Sciences team in South San Francisco. Reporting to the Sr. Director of Biologics, you will be primarily responsible for the biophysical characterization of tool and therapeutic biologic molecules, peptides, and small molecules. You will drive the analysis of molecular interactions using techniques such as bi-layer interferometry (BLI), surface plasmon resonance (SPR), thermophoresis, and calorimetry. Beyond the bench, you will act as a subject matter expert in the design of optimal constructs, purification regimes, and structural characterization. For antibody discovery projects, you will play an integral role in repertoire discovery and computational biologics engineering. This is a highly collaborative role where you will liaise between our laboratory efforts and insitro’s data science and AI teams to advance a high-value portfolio of candidates into the clinic. This role is laboratory-based and requires a full-time onsite presence at our South San Francisco headquarters.
