• Support site selection and onboarding of a new Drug Substance Site 
• Lead the tech transfer of a Phase 3 vaccine manufacturing process to external Drug Substance manufacturing partners, ensuring successful process scale-up, validation, and commercial readiness
• Execute technology transfer strategies, project plans, governance structures, and risk mitigation plans to ensure successful transfer and lifecycle management of manufacturing processes
• Lead process characterization, comparability assessments, scale-up/scale-down studies, and process validation activities to establish robust manufacturing processes and support regulatory submissions. Develop and maintain the Drug Substance process control strategy, including process parameter criticality assessments, critical process parameter (CPP) identification, critical in-process controls (cIPCs), and contribute to continued process verification (CPV) strategies
• Author, review, and approve CMC technical documentation, including technology transfer packages, process characterization reports, validation documentation, regulatory submission content, comparability reports, and responses to Health Authority inquiries. 
• Drive project execution by managing technical deliverables, timelines, risks, and cross-functional dependencies, ensuring alignment with organizational priorities, regulatory requirements, and donor commitments. 
• Ensure compliance with cGMP, regulatory expectations, quality standards, and organizational procedures throughout process development, technology transfer, validation, and commercial manufacturing 
• Contribute to funding proposals, grant reporting, and strategic planning efforts to advance vaccine access and equity worldwide

• Bachelor’s degree in biochemistry, chemistry, biology, chemical engineering or related pharmaceutical science
• Minimum of 7+ years of experience in biopharmaceutical CMC, manufacturing, process development, and technology transfer
• Demonstrated experience in biopharmaceutical manufacturing, MS&T, and/or process development environments, including hands-on experience with mammalian or viral cell culture, upstream and downstream processing, and purification operations (e.g., chromatography, filtration/ultrafiltration, viral clearance)
• Prior technology transfer experience, including leading or supporting site-to-site, scale-up, or CDMO transfers
• Experience with adenovirus-vectored vaccines or other viral vector platforms (e.g., AAV, poxvirus, lentiviral vectors) is strongly preferred; candidates with comparable complex biologics manufacturing experience will also be considered
• Strong analytical, problem-solving, organizational, communication, and interpersonal skills, with the ability to work effectively both independently and collaboratively across cross-functional teams, global stakeholders, and diverse audiences
• Commitment to health equity and improving immunization access in underserved populations

Preferred Skills and Experience:

• Direct experience operating in cGMP-regulated environments, including support for non-conformance investigations, root cause analysis, change control, and CAPA implementation
• Working knowledge of ICH guidelines and global regulatory requirements (e.g., FDA, EMA, MHRA), with experience supporting late-stage development programs, regulatory submissions (e.g., BLA/NDA), and commercial supply activities 
• Experience working with external manufacturing partners

Other: 

• Subject to a criminal background investigation 
• Request for three professional references 
• Verification of education/degrees 
• Travel up to 25%
