• Provide technical leadership across upstream/downstream, analytical, formulation, fill/finish, and stability, guiding fit-for-stage development decisions (e.g., scale-up strategy, formulation/container strategy, stability approach) and tech transfer readiness.  
• Ensure phase-appropriate GMP readiness and campaign execution at the CDMO, including deviation/change/CAPA alignment with Quality and ensuring testing and disposition timelines support clinical needs.  
• Drive CMC regulatory deliverables (CMC sections of submissions/amendments) and executive-level communication of status, decisions, risks, and mitigation plans; build/lead high-performing internal and matrixed teams.  

Required Qualifications 

• Advanced degree (PhD preferred; MS with significant experience considered) in Chemical Engineering, Biochemistry, Pharmaceutical Sciences, or related discipline. 15+ years of biologics CMC experience spanning development through GMP manufacturing and external manufacturing oversight (drug substance and/or drug product). 
• Proven ability to define CMC strategy and translate it into cross-functional deliverables, integrated plans, timelines, and budgets, with strong program leadership and operating rigor.  
• Demonstrated success managing external collaborations/CDMOs to deliver CMC development and manufacturing outcomes in fast-paced, matrixed environments.  
• Strong technical breadth in at least one major CMC area (and ability to lead across all), including upstream/downstream, analytics, and/or fill/finish/drug product with stability/tech transfer exposure.  
• Deep working knowledge of cGMP/GxP and quality systems, with clear, concise communication and stakeholder influence skills.  

Desired Skills 

• Define and execute strategic vision to advance scientific innovation, translating emerging insights into high-impact initiatives, roadmaps, and measurable outcomes. 
• Act decisively and own end-to-end accountability, making timely, data-informed decisions, taking responsibility for results, and delivering against commitments in dynamic environments.
