Senior Scientist, Vaccine Drug Product Development

Senior Scientist, Vaccine Drug Product Development

Introduction to the Role

Join our Vaccines Drug Product Development team to shape the next generation of preventative therapies. We are seeking a highly motivated Senior Scientist with experience in vaccine formulation development, adjuvant formulations, and co-formulated drug products. You will design and develop formulations and drug product processes spanning phase 1 through pivotal clinical development, with a focus on multi-antigen/adjuvant combinations and other vaccine modalities. You will drive development strategies, influence CMC decisions, manage external partners, and connect near-term deliverables to long-term patient impacts.

Key Responsibilities

You will work in a laboratory environment focused on vaccine drug product development, supporting programs from early formulation screening through clinical manufacturing readiness. Additionally, you will:

• Vaccine Formulation Development: Design and execute formulation studies for vaccine drug products, including co-formulated multi-antigen/adjuvant combinations and other vaccine modalities. Evaluate antigen–adjuvant interactions, excipient compatibility, and stability to inform pipeline advancement decisions.
• In Vitro Characterization: Perform experiments to evaluate formulation attributes such as antigen integrity, adsorption/desorption profiles, particle size, encapsulation efficiency, and colloidal stability. Generate data packages that support formulation down-selection and process development decisions.
• Drug Product Process Design and Scale-Up: Design fit-for-purpose drug product processes (e.g., mixing, encapsulation, sterile filtration, lyophilization). Conduct scale-up and robustness studies to build process–product understanding across clinical phases. Contribute to technology transfer activities to manufacturing sites or CMOs/CDMOs.
• Documentation and Regulatory Authoring: Author technical reports, protocols, and development summaries. Draft and contribute to CMC sections for INDs, and BLAs (i.e., process descriptions, formulation justifications, clinical compatibility). Maintain documentation in compliance with internal practices.
• Cross-Functional Representation: Represent Drug Product on CMC sub-teams; collaborate with other functions to align formulation and process plans with program timelines.
• Scientific Contribution and Lab Operations: Present findings at internal forums; contribute to external publications or conferences where appropriate. Stay current with emerging scientific literature and technology. Support coordination and maintenance of laboratory equipment.

Education & Experience Requirements

• Education: BS, MS, or PhD in Biochemistry, Chemistry, Chemical/Biochemical Engineering, Immunology, Pharmaceutics or related fields of study.
• Experience: BS: 7+ years; MS: 3+ years; PhD: 0+ years of experience in biopharmaceutical or vaccine development.

Required Skills & Experience

• Formulation Development: Strong understanding of vaccine formulation principles, including adsorption kinetics, antigen–adjuvant interactions, buffer/excipient selection, and stability assessment (chemical, physical, colloidal). Ability to independently design and execute formulation studies with clear decision criteria.
• In Vitro Characterization: Familiarity with biophysical characterization techniques such as DLS, HPLC/UPLC, LC-MS, UV/Fluorescence, ELISA/Binding assays, DSC/DMA, zeta potential, encapsulation efficiency, particle size and PDI, adsorption/desorption profiling, residual solvent/detergent analysis, Karl Fischer, osmolality, sterility/endotoxin, and appearance/particulate assessments.
• Data Interpretation & Decision-Making: Ability to design experiments with clear decision criteria, critically interpret results, and connect experimental outcomes to inform next steps.
• Process Engineering: Familiarity with unit operations relevant to vaccines (e.g., homogenization/emulsification, sterile filtration concepts, or LNP formation via microfluidics). Exposure to process scale-up considerations is a plus.
• Scientific Communication: Ability to clearly document experimental work, summarize findings in written reports, and present data to multidisciplinary teams.
• Collaboration: Strong communication and interpersonal skills, with the ability to work effectively across multidisciplinary scientific teams.

Desirable Skills & Experience

• Process Engineering: Experience with unit operations relevant to vaccines (e.g., homogenization/emulsification,
