Principal Scientist, Commercial and Late-Stage Purification Process Development

Key Accountabilities/Core Job Responsibilities: Serve as downstream purification technical lead for commercial manufacturing including continued process verification, investigations, deviation support, and cross-site alignment. Support lifecycle management activities for commercial products, including process improvements, tech transfer validation activities, local and cross-site change management, regulatory filing updates (CBE, PAS, Ex-US expansion), and responses to health authority questions. Drive technical continuity and alignment across CDMO and internal manufacturing sites by ensuring process understanding, lessons learned and technical decisions are consistently captured and applied. Design, oversee, and interpret small-scale process development studies that inform large-scale manufacturing decisions, support root-cause investigations, and enable lifecycle improvements. Build and maintain technical risk assessments (e.g., FMEA) and process history files to support robust commercial manufacturing and future late-stage programs. Support the incoming late-stage process development pipeline and commercial programs by applying best practices, platform knowledge, and prior manufacturing experience while contributing to standardization of lifecycle management practices. Qualifications/Skills: Typically requires a PhD in Biology, Biochemistry, Chemical Engineering, or a related scientific discipline, plus 10+ years of related work experience.
