Pfizer Senior Scientist, Crystallization Process Development in Groton, Connecticut
Why Patients Need You
Pfizer's purpose is to deliver breakthroughs that change patients' lives. Research and Development is at the heart of fulfilling Pfizer's purpose as we work to translate advanced science and technologies into the therapies and vaccines that matter most. Whether you are in the discovery sciences, ensuring drug safety and efficacy or supporting clinical trials, you will apply cutting edge design and process development capabilities to accelerate and bring the best in class medicines to patients around the world.
We are seeking a senior scientist to join the Crystallization Technology Laboratory as part of Chemical Research and Development (CRD) team in Groton. The successful candidate will be responsible for designing and developing robust scalable Active Pharmaceutical Ingredient (API) crystallization processes for use at pilot-plant and commercial scale. They will apply chemical engineering principles, computational modeling approaches, and lab-scale experimental techniques to gain process understanding and to optimize the processes for safety, efficiency, and robustness.
CRD, as part of Worldwide R&D in Pharmaceutical Sciences, is responsible for the development of process technology to manufacture active pharmaceutical ingredient's (API). CRD scientists engage in all facets of development from small-scale synthesis in support of medicinal chemistry programs, to the development of the commercial synthetic route. CRD chemists and engineers collaborate with manufacturing specialists for API production in kilo-lab and pilot plant facilities, as well as provide support for technology transfer to Pfizer manufacturing sites and third-party facilities.
The successful candidate will work on API project teams in the crystallization process design and development, technology transfer, and regulatory filing activities for new small molecule candidates. They will work closely with process chemistry, materials science, and drug product development colleagues to identify and optimize API target attributes. They will develop technology for clinical projects to deliver API that meets the targeted physical and chemical quality attributes by applying knowledge of crystallization and solid form science. Working as part of multidisciplinary teams, the scientist will develop robust and scalable processes suitable for transfer to a commercial manufacturing facility. The candidate will also improve capabilities of the group through the development and advancement of new technologies related to crystallization process development such as sono-crystallization, continuous crystallization, and integrated process control. They will develop and utilize computational models such as thermodynamic predictions, solid form modelling, and population balance models to facilitate design of crystallization processes. Given the dynamic team environment and fast-paced project timelines, strong interpersonal and communication skills are essential.
