We are looking for a dynamic and experienced Principal Scientist to join our External Manufacturing (ExM) Manufacturing Science & Technology (MS&T) team. In this high-impact role, you will serve as a critical technical leader, providing expert support and oversight for parenteral drug product manufacturing at Contract Manufacturing Organizations (CMOs) within North America.

What You'll Do

• Act as Process Owner: Drive continuous process verification (CPV) and Operational Excellence (OPEX) initiatives at CMO sites, identifying and executing process robustness improvement projects to reduce supply risk.
• Be the Technical Point of Contact: Serve as the BMS Site Implementation Lead for CMO partners, including Person in Plant (PIP) support during technical transfers and commercial manufacturing activities.
• Lead Investigations: Lead root cause analysis, impact assessments, and corrective/preventive action (CAPA) development for out-of-trend or out-of-specification results and deviations in drug product manufacturing.
• Support Regulatory & CMC Activities: Contribute technical input to CMC documents, support responses to Global Health Authority queries, and assist during plant inspections.
• Drive Change Management: Lead and coordinate change requests and complex process deviations, sometimes across multiple sites or functions.
• Cross-Functional Collaboration: Represent MS&T on project teams, working closely with Quality Assurance, Global Procurement, Supply Chain, Supply Relationship Management, and Product Development.

• Technical Skills & Expertise
• Recognized subject matter expert in sterile/parenteral manufacturing processes and associated global regulatory requirements (e.g., FDA cGMP).
• In-depth knowledge of engineering, analytical, and regulatory (cGMP, EHS) aspects of drug product manufacturing, validation, and quality systems.
• Strong background in statistical process analysis, including proficiency with tools such as Minitab or JMP; familiarity with Design of Experiments (DoE), Quality by Design (QbD), and Risk Assessment frameworks.
• Experience with formal risk assessment tools such as pFMEA and Ishikawa (Fishbone) analysis.
• Demonstrated experience with sterile drug product manufacturing operations
