• 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

• Extensive expertise in the analytical testing of raw materials, excipients, and/or package components, preferably within a cGMP environment, with comprehensive knowledge of GMPs, ICH guidelines, compendial requirements, and applicable FDA guidance
• Demonstrated ability to develop and execute technical strategy and to exercise influence without direct authority within a matrixed organization
• Excellent scientific communication, creativity, and interpersonal skills
• Proven experience mentoring scientists and collaborating cross-functionally to deliver high-quality results within established timelines
