## Description

Job Description Summary #LI-Onsite Internal Title: Principal Scientist I Location: Cambridge, MA We are seeking a highly motivated and scientifically driven Principal Scientist I to join the Molecular Histology Laboratory within Preclinical Safety and Investigative Pathology. This position will serve as a technical subject matter expert responsible for developing, optimizing, and implementing advanced tissue-based assays that support preclinical toxicology, investigative pathology, translational research, and drug development programs. The successful candidate will possess deep expertise in molecular localization technologies, digital pathology, and tissue-based biomarker assessment. This individual will provide hands-on laboratory leadership in assay development and execution while collaborating closely with pathologists, laboratory scientists, and multidisciplinary project teams. This role requires extensive experience with immunohistochemistry (IHC), multiplex IHC, in situ hybridization (ISH/RNAscope), automated staining platforms, digital pathology workflows, and image analysis technologies. Job Description Key Responsibilities Molecular Localization and Assay Development Develop, optimize, validate, and implement tissue-based assays, including immunohistochemistry (IHC), multiplex immunofluorescence, and in situ hybridization (ISH/RNAscope). Serve as a molecular histology subject matter expert by evaluating antibodies, probes, controls, and assay strategies to generate robust, reproducible, and scientifically meaningful data. Operate, maintain, and optimize automated staining platforms, including Ventana ULTRA and Leica BOND systems, while developing automated workflows for IHC and ISH assays. Troubleshoot complex technical challenges and establish best practices for assay performance and quality control. Establish standardized protocols, acceptance criteria, troubleshooting guides, and assay performance metrics. Utilize digital pathology workflows, including whole-slide imaging, image analysis, and data management using LIMS and electronic laboratory notebook (eLN) platforms. Maintain accurate, contemporaneous, and traceable experimental records in approved electronic systems.
