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.

What You will Achieve

We are seeking a highly motivated chemical engineer for the role of Senior Scientist -Chemical Engineer for API Process Development within Chemical Research and Development (CRD) in Groton , CT . You will join a diverse team responsible for developing A ctive P harmaceutical I ngredients (API) processes for use at manufacturing plants across Pfizer's network. Chemical engineering principles contribute to the successful development , optimization and scale up of API manufacturing processes. You will design and perform engineering-related laboratory experiments , in combination with process simulation and statistics. Strong communication , high technical aptitude, and creativity to foster original ideas are required for success in this position.

CRD, as part of Pfizer R&D in Pharmaceutical Sciences, is responsible for the development of process technology to manufacture active pharmaceutical ingredients (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. In collaboration with chemists and analysts, y ou will lead the engineering activities during process development, process scale up, and technology transfer to our clinical and commercial manufacturing sites and external facilities. Given the dynamic team environment and fast-paced project timelines, strong interpersonal and communication skills are essential. This laboratory-based position offers the opportunity for cross-training and innovation of new technologies and processes .
