Moderna is seeking an experienced and highly motivated Senior Research Associate to join the Clinical Biomarker Laboratory (CBL) Immunoassay and Cell Based Assay group. This laboratory-based role will support the development, qualification, validation, transfer, and clinical implementation of cell-based assays, virus neutralization/functional antibody assays, and ligand-binding assays (LBAs) used to characterize vaccine-induced immune responses and support clinical vaccine development programs, while also contributing to biomarker and immunogenicity testing across Moderna's infectious disease, oncology, and autoimmune disease portfolio.
The successful candidate will bring strong hands-on experience with mammalian cell culture, cell-based functional assays, and immunoassays and will be expected to independently execute assay development and optimization experiments, qualification/validation studies, clinical sample testing, data analysis, troubleshooting, and compliant documentation in a regulated clinical laboratory environment.
Direct experience with virus neutralization or other functional antibody assays is preferred, including cell culture-based neutralization assays, reporter-based or pseudovirus neutralization platforms, and/or hemagglutination inhibition (HAI) assays. Experience with ligand-binding platforms such as ELISA or electrochemiluminescence-based assays is also highly desirable.
The Senior Research Associate will work closely with the clinical Biomarker Laboratory Immuno-Assay Lead, and also with biostatisticians, Quality/ Compliance partners, and other cross-functional stakeholders to deliver high-quality, traceable, and regulatory-compliant bioanalytical data supporting Vaccine clinical development programs.
