The Principal Scientist of Formulation & Drug Product Development will be responsible for the end-to-end Drug Product Development of Live Biotherapeutic Products (LBPs). Works closely with the Drug Substance, Analytical, Quality Control, Process Development, Drug Product Manufacturing and Quality Assurance teams to facilitate the development of robust, scalable and reproducible formulations and processes for LBPs.


  • Formulation development and optimization, process development and optimization, scale-up, technology transfer of Live Biotherapeutic Products (LBPs).
  • Independently design and perform hands-on experiments on oral solid dosage unit operations, including, but not limited to, blending, roller compaction, encapsulation, banding, coating, tableting and packaging.
  • Design and perform experiments using DOE, statistical tools for data analysis and principles of Quality-by-Design for Drug Product Development.
  • Design development stability strategies, including selection and technical justification for packaging materials.
  • Familiarity with the role that physicochemical properties play in drug delivery and formulation design.
  • Pursue and ensure superior stability and manufacturing feasibility.
  • Design and conduct formulation studies at various stages of development to provide data to support early phase clinical trial, such as stability, solubility and effects of pH.
  • Characterize Drug Substance: Isotherm analysis, particle sizing, bulk/tapped density, DSC studies etc.
  • Evaluate and develop formulations for alternate drying technologies (electrostatic spray dry, fluid bed dry, freeze dry etc)
  • Design and develop formulations for pediatrics
  • Train and mentor junior level scientists, as needed.
  • Support GMP manufacturing, packaging, and/or labeling operations, as needed.
  • Understand and practice good documentation practices. Document all work in laboratory notebook(s) or other acceptable forms (e.g., batch records).
  • Write and review SOPs, development protocols, and technical reports.
  • Assist with troubleshooting, deviations, and investigations, as requested.
  • Contribute to preparation and review of regulatory documents for submission to FDA and other regulatory authorities.
  • Lead or contribute to invention disclosures and patentable advancements.
  • Ensure development of technologies and scientific innovation that improve the capability to formulation live biotherapeutics


Experience and Skills


  • Ph.D. in Pharmaceutics or related discipline with 10+ years of relevant experience. Non-Ph.D. candidates with 15+ years of relevant experience will be considered. Key relevant experience should include hands-on formulation and process laboratory experience to support solid oral dosage forms.
  • Hands-on experience with pharmaceutical unit operations, equipment and instrumentation to support formulation activities for solid oral dosage forms.
  • Hands-on experience in independently running small-scale processing equipment for solid oral dosage forms is very important for this role.
  • Understanding and incorporation of DOE, statistical data analysis and QBD into product development will be a huge plus.
  • Demonstrated ability to write technical reports and other technical documentation (e.g., protocols, SOPs, etc.).
  • Understand and implement FDA and ICH requirements into Product Development (e.g., Quality-by-Design) for IND, CTA, IMPD and Quality submissions.
  • Knowledge of pharmaceutical GLPs and GMPs, especially as related to solid oral dosage form manufacturing.
  • Motivated self-starter who can work independently with minimal supervision.
  • Excellent professional, interpersonal skills and communication skills.
