What You’ll Do:

The Senior Director, Drug Substance Commercial Manufacturing is accountable for the performance and results of key initiatives, goals and assets of drug substance portfolio and will own Drug Substance (DS) technology transfer, Manufacturing Science and Technology (MSAT), manufacturing oversight, and Operational Excellence (OpEx) for assigned CDMO sites in Kailera’s CDMO network. Reporting to the Vice President (VP), Commercial Manufacturing, this leader is the sponsor-side technical and operational owner of the DS process at those sites, from transfer-in and validation through launch, routine commercial supply, continued process verification (CPV), and lifecycle management. Where an assigned CDMO is also developing new processes for Kailera, the role provides sponsor oversight of that work.

The role develops and executes DS strategy with the VP to achieve key business objectives and leads the MSAT and manufacturing oversight team and the day-to-day relationship with multiple CDMOs. This role works closely with CMC Development and Analytical, who retain decisions on process development and on analytical methods and specifications. This person ensures the agreed processes and methods are implemented at the CDMO exactly as approved, with no unapproved changes. They coordinate with peer DS leaders to keep process knowledge, controls, and analytical performance consistent across the network, and partners with Quality, Regulatory CMC, Drug product, Supply Chain, and the Project Management Office (PMO).
