• Build strong, collaborative vendor relationships while establishing clear expectations, milestones, metrics, and accountability.
• Proactively identify risks, elevate when necessary, and drive vendors to deliver right-first-time and on-time execution for release, stability, investigations, method transfers, and regulatory commitments.
• Lead vendor performance improvement using objective data and ensure corrective actions result in sustained improvement.
• Travel to vendor laboratories as needed to troubleshoot, understand execution firsthand, align teams, and accelerate resolution.

Communication, Regulatory & Cross-Functional Leadership

• Communicate complex scientific, quality, and regulatory issues clearly, concisely, and persuasively to vendors, technical teams, and senior leadership.
• Author and critically review high-quality analytical and regulatory content supporting BLAs, supplements, validation, comparability/bridging, investigations, and inspections.
• Translate complex issues into clear risks, recommendations, decisions, owners, and actions.
• Partner effectively with Quality, Regulatory, MS&T, Supply Chain, and other functions to ensure analytical activities are scientifically sound, compliant, inspection-ready, and aligned with regulatory commitments.

Qualifications:

• 15+ years of relevant industry experience preferred. Title is commensurate with years of experience.
• Significant commercial-stage biologics experience with demonstrated expertise in bioassays, particularly monoclonal antibody potency assays required and cell therapy potency experience a strong plus.
