Senior Scientist, Materials Science

Company: Pfizer
Location: Groton
Posted on: June 8, 2021

Job Description:


The Senior Scientist - Materials Science position is a laboratory-based position with responsibility for investigating and understanding the solid state chemistry of Pfizer's drug molecules. Responsibilities include generating solid state chemistry data using state-of-the-art instrumentation and computer models, and interpreting the data to allow new medicines to be brought to the market. This role serves on multidisciplinary project teams and is responsible for defining the final drug substance form (salt/polymorph/hydrate) of active pharmaceutical ingredients (API) and the preferred physical attributes (particle shape/particle size/surface energy) needed for optimum API and drug product performance. The position is based in Groton, CT (USA).


  • Conduct solid state physical and chemical characterization of small molecules of pharmaceutical relevance. This includes particle characterization (e.g., particle size, shape) and solid state characterization (e.g., spectroscopy, X-ray powder diffraction, thermal analysis).
  • Crystallize neutral molecules, salt and co-crystal forms of drug candidates (including hydrates, solvates and polymorphs) and evaluate these forms for acceptability as drug substances as it relates to chemical manufacturing and formulation into pharmaceutical products.
  • Apply state-of-the-art computational approaches to predict the properties and performance of crystalline and amorphous drug substance samples.
  • Oversee the work of external partners conducting laboratory studies, and provide tactical guidance and critical analysis of raw data.
  • Solve scientific problems using contemporary solid state experimental and computational techniques.
  • Participate on multidisciplinary project teams, and collaborate with colleagues to define and implement screening and characterization strategies according to project timelines.
  • Draft and review sections of regulatory submissions as well as delivering reports to support patenting Pfizer's intellectual property.
  • Provide materials science support for colleagues in other lines.
  • Lead the development of new scientific approaches and knowledge within the global Materials Science organization.


  • A PhD in chemistry, engineering, materials science, or pharmaceutics (or equivalent subject) and 0-4 years of relevant experience is required, or a MS in chemistry, engineering, materials science, or pharmaceutics (or equivalent subject) and 5+ years of relevant experience is needed.
  • The candidate should have experience in small molecule crystallization and solid state characterization (such as x-ray powder diffraction, polarized light microscopy, differential scanning calorimetry, thermogravimetric analysis, NMR, etc).
  • Strong data analysis skills and knowledge of statistical concepts are also needed.
  • A strong interest and motivation to learn new technologies and concepts is expected.
  • Good organizational skills, the ability to work independently, and excellent oral and written communication skills are required.
  • Experience with using contemporary computational approaches to predict the properties and performance of pharmaceutical materials is preferred.
  • Understanding of the physical properties needed for drug substance manufacture and formulation into drug product is desired


No special physical/mental requirements are needed for this position.


No special non-standard work schedule, travel or environmental requirements exist for this position.

Sunshine Act

Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
