Associate Principal Scientist, Adjuvant CMC SME

Introduction to Role

Join our Vaccines Drug Product Development team to shape the next generation of preventative therapies. We are seeking a highly motivated Associate Principal Scientist with deep experience in vaccine adjuvants and complex, co-formulated drug products. You will independently 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 impact.

Key Responsibilities

• Adjuvant and Vaccine Formulation: Lead efforts to develop co-formulated multi-antigen/adjuvant (aluminum-based, lipid-based, and novel adjuvants) products. More broadly develop and optimize formulations for mRNA-LNPs, bioconjugates, virus-like particles (VLPs), and recombinant proteins.
• Drug Product Process Design and Scale-up: Design fit-for-purpose drug product processes (e.g., mixing, suspension handling, encapsulation, sterile filtration, aseptic fill-finish, lyophilization when applicable), conduct scale-up and process robustness studies, and build process-product understanding and support development across clinical phases.
• GMP and External Manufacturing: Translate processes into GMP-ready operations; review batch records; coordinate tech transfer to internal sites and CMOs/CDMOs; provide on-floor and remote support for engineering and GMP batches.
• Cross-Functional Leadership: Serve as the Drug Product CMC representative on vaccine program teams; collaborate closely with Drug Substance, Analytical Sciences, Regulatory, Quality, Clinical, Supply Chain, and Project Management to align strategy and execution.
• Regulatory Authoring and Health Authority Interactions: Author and review CMC sections for INDs, BLAs, and MAAs; contribute to responses to information requests and support health authority queries with clear scientific rationales for formulation and process decisions.
• Analytical Strategy Interface: Partner with analytical teams to define fit-for-purpose methods supporting vaccine and adjuvant characterization (e.g., potency/antigen integrity, particle size, encapsulation efficiency, adsorption profiles, residuals, sterility/endotoxin), and ensure data quality supports formulation selection and process control.
• Technical Leadership and Communication: Plan and execute experiments; analyze and interpret data; deliver concise, decision-driving summaries to internal stakeholders and external partners; present findings at internal forums and scientific meetings as appropriate.
• Documentation and Compliance: Write protocols, reports, and technical risk assessments; ensure compliance with cGMP, GLP where relevant, and corporate quality standards; maintain laboratory notebooks and support equipment qualification/maintenance as needed.
  
  

Education & Experience Requirements

• Education: BS, MS, or PhD in Chemistry, Biochemistry, Pharmaceutics, Chemical/Biochemical Engineering, Immunology, or related field.
• Experience: BS: 10 years; MS: 7 years; PhD: 5 years in biopharmaceutical or vaccine development settings.
• Demonstrated expertise in vaccine adjuvant systems (aluminum salts, lipid-based systems, other novel adjuvants) and co-formulated multi-antigen/adjuvant products.
• Hands-on experience with one or more modalities: mRNA-LNPs, bioconjugates, VLPs, recombinant protein vaccines.
• Proven track record in GMP manufacturing, tech transfer to CMOs/CDMOs, and clinical supply support.
  
  

Desired Skills & Experience

• Formulation Development: Strong understanding of vaccine formulation principles, including adsorption kinetics, antigen–adjuvant interactions, buffer/excipient selection, stability (chemical, physical, colloidal), and immunogenicity considerations relevant to product design.
• Process Engineering: Experience with unit operations relevant to vaccines (e.g., LNP formation via microfluidics, homogenization/emulsification, suspension management, sterile filtration, aseptic filling, lyophilization assessment when applicable).
• Analytical Interfaces: Familiarity with biophysical and biochemical 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.
• CMC Strategy and Documentation: Experience reviewing batch records, authoring IND/BLA/MAA CMC sections, and supporting health authority interactions.
• Cross-Functional Ways of Working: Skilled at interfacing with CMC project leader, Clinical, Regulatory, Quality, Drug Substance, Supply Chain, and Program Management to align technical plans with program milestones and risk posture.
• External Collaboration: Comfortable negotiating scope and timelines with CMOs, overseeing execution, resolving deviations, and driving continuous improvement.
• Data and Decision Quality: Ability to connect experimental outcomes to program decisions; build evidence packages that withstand internal governance and external scrutiny.
  
  

Ways of Working and Behaviors

• Proactive and Motivated: Anticipates risks and opportunities; drives timely, high-quality execution without close supervision.
• Engaged and Collaborative: Builds strong relationships across disciplines; communicates clearly and respectfully; fosters transparency and shared accountability.
• Patient Impact Focus: Passionate about translating technical work into better patient outcomes; prioritizes decisions that advance quality, safety, and supply reliability.
• Systems Thinking: Connects the what to the how—navigates complex technical problems, aligns stakeholders, and maintains momentum while understanding how work fits within Drug Product and the broader CMC landscape.
• Scientific Rigor and Integrity: Upholds data integrity, methodical experimentation, and clear documentation; embraces feedback to improve outcomes.
  
  

Working Model

We value in-person collaboration and operate, on average, a minimum of four days per week from the office while maintaining flexibility to balance individual needs and team priorities.

Location and Travel

• Primary Site: Gaithersburg, MD (Biopharmaceuticals R&D)
• Travel: Up to10% travel, primarily to CMOs/CDMOs, internal manufacturing sites, and health authority or cross-functional meetings as needed for tech transfer and GMP support.
