This Scientist II will independently design, execute, and analyze research studies and will drive one or more analytical development projects for AAV-based gene therapy programs. The role provides technical leadership in the development, optimization, qualification, validation, and transfer of analytical assays, including cell-based potency and molecular methods such as qPCR and ddPCR. The Scientist II will apply broad scientific knowledge and novel approaches to establish AAV mechanisms of action in cellular systems, resolve moderately complex technical issues, and support GMP manufacturing, material release, and regulatory submissions in collaboration with groups across CMC, Quality, QC, and external partners.
The ideal candidate is highly collaborative, detail-oriented, able to manage multiple priorities, and effective in a fast-paced environment. The Scientist II is expected to exercise sound scientific judgment, communicate complex technical issues clearly, build alignment across functions, and serve as a technical resource to colleagues. This is a highly visible and impactful role in our CMC organization.
