As part of Our Company's Manufacturing Division, the Sterile Drug Product Commercialization group provides the technical process leadership and laboratory capabilities for late‑stage and commercial drug product processes for biologics. It is the division's leader in sterile product and process development, responsible for late‑stage commercialization activities including process scale‑up, technology transfer to internal and external sites, process validation, authoring of regulatory submissions, and support of significant manufacturing investigations.

The group establishes the science, engineering and knowledge required for today’s innovative and accelerated commercialization of biologics and combination products.

We are seeking an experienced Principal Scientist to advance and commercialize biologics pipeline programs. As a member of the drug product team, the Principal Scientist will focus on driving excellence in process characterization, scale‑up, transfer and process validation activities.

• Execute and provide oversight to biologics product and process design, development, characterization, technology transfer, and robust commercial validation.
• Lead and/or serve on cross‑functional biologics drug product (DP) working groups and manage DP activities through filing and Process Performance Qualification (PPQ), including registration stability study execution, process characterization plan and execution, tech transfer control strategy, process development, PPQ readiness, PAI readiness, approval, launch and post‑launch support.
• Ensure commercialization programs meet requirements related to science, quality, reliability, schedule, and cost.
• Drive strategic initiatives (technical and/or business process related) in the department and with partner groups, enabling more efficient and rapid commercialization of innovative products.
• Provide mentorship, technical oversight and strategic guidance to employees, using advanced experience to guide others in addressing non‑routine or difficult issues.
