About The Position

The Scientist, Cell Culture Process Development (Pivotal & Commercial) leads aspects of cell culture development, including commercial process development and process characterization for biologics programs during pivotal phases (Phases II/III and post-launch). The role also leads projects in cell culture process technology development and platform process evolution, and supports cell culture-related regulatory documentation. The position involves developing and characterizing processes for monoclonal antibodies, multi-specifics, and novel modalities; supporting pivotal activities through BLA filing and process performance qualification; and partnering with global manufacturing sciences and technologies on technology transfer, investigations, and person-in-plant activities. The Scientist performs hands-on cell culture work at laboratory and pilot scales, conducts statistical analyses and modeling, authors and reviews technical and regulatory documents, and collaborates across functions. The role may manage direct and indirect reports and mentor junior team members. The listed salary range is $146,540 to $189,640. The position may also be eligible for a discretionary annual bonus, discretionary stock-based long-term incentives, paid time off, and company-sponsored medical, dental, vision, and life insurance, subject to applicable plan terms and eligibility.
