Role Summary
The Senior Manager/Associate Director, MSAT/Process Characterization and Validation Readiness will lead AAV process characterization, technology transfer, control strategy development, and PPQ readiness activities across Sf9/baculovirus and HEK-based manufacturing platforms. This role will partner closely with internal CMC functions and CDMOs to ensure late-stage manufacturing processes are robust, well characterized, and ready for clinical and commercial execution.
