About this role

Scientist, Reagent Process Development Fremont, CA At Personalis, we are transforming the active management of cancer through breakthrough personalized testing. We aim to drive a new paradigm for cancer management, guiding care from biopsy through the life of the patient. Our highly sensitive assays combine tumor-and-normal profiling with proprietary algorithms to deliver advanced insights even as cancer evolves over time. Our products are designed to detect minimal residual disease (MRD) and recurrence at the earliest timepoints, enable selection of targeted therapies based on ultra-comprehensive genomic profiling, and enhance biomarker strategy for drug development. Personalis is based in Fremont, California. Summary: We are seeking a results-driven, hands-on Process Development Scientist to join our exciting team. In this role, you will be responsible for translating R&D breakthroughs into reagent production processes, specifically focusing on formulations, packaging, and QC assays/specifications. This position bridges R&D and Manufacturing, ensuring that new products are robust, scalable, cost-effective, and compliant with ISO 13485/GMP standards. Responsibilities: Formulation Process Development: Develop and optimize manufacturing methods for reagent formulations to ensure consistency, functionality, and stability. Reagent Packaging Process Development: Design and implement accurate and reproducible filling, dispensing, labeling, and sealing processes for liquid reagents into tubes and multi-well plates. Scale-Up: Transition laboratory-scale formulations and manual filling processes into robust, automated, or semi-automated production-scale processes. Evaluate outsourcing to contract manufacturers, as needed. Design scaled up and practical manufacturing processes, while identifying Critical Process Parameters and Critical Quality Attributes. QC Assay Development & Specs: Develop relevant in-process and finished product test methods
