• Monitor regulatory, compendial (USP/NF, Ph. Eur., JP), and industry trends; lead gap assessments and implementation plans
• Champion operational excellence and efficiency in raw material testing through use of digital tools and innovative technologies while ensuring data integrity and right-first-time execution
• Partner cross-functionally with Analytical Leadership, Quality, Procurement, Materials Management, and Pharmaceutical Sciences to align an integrated raw material strategy to meet the clinical portfolio and supply needs across all modalities
• Mentor and develop scientists, building technical depth and raw materials expertise across the CoE
