About the Role:

The Senior Scientist will serve as the analytical potency SME within CMC Analytical Development, supporting biologics programs including AAV-based gene therapies, monoclonal antibodies, and antibody conjugates. This role leads the development, qualification/validation, transfer, and lifecycle management of potency assays used to monitor critical quality attributes (CQAs) of drug substance and drug product. The position defines and executes potency strategy, designs robust cell-based functional assays, and ensures regulatory-compliant data generation across all development stages in alignment with cGMP and global regulatory requirements.

Your Contributions (include, but are not limited to):

• Act as potency SME on cross-functional CMC teams; own analytical deliverables, timelines, and risk mitigation

• Establish potency strategy aligned with mechanism of action and regulatory expectations, linking CQAs to clinical relevance

• Develop, optimize, qualify, validate, and manage lifecycle of potency assays, particularly for viral vector–based gene therapies

• Design and execute cell-based functional assays assessing transgene expression, biological activity, infectivity/transduction, and MOA-relevant endpoints

• Develop molecular and biochemical assays (qPCR/ddPCR, RT-qPCR, ELISA, reporter assays, flow cytometry, Western blot) as appropriate

• Perform statistical analysis and data interpretation; author validation protocols, technical reports, and CMC regulatory documentation

• Lead analytical method transfer to QC and CDMOs, including training and method comparability assessments

• Support IND/IMPD and BLA/MAA submissions and respond to health authority inquiries

• Ensure compliance with cGMP, ICH guidelines, and internal quality systems

• Mentor junior scientists and promote scientific rigor and collaboration

Requirements:

• PhD in Molecular Biology, Cell Biology, Virology, Biochemistry, or related field with some industry experience; OR MS with 3
