Pfizer Principal Scientist in Andover, Massachusetts
A career at Pfizer offers opportunity, ownership and impact.All over the world, Pfizer colleagues work together to positively impact health for everyone, everywhere. Our colleagues have the opportunity to grow and develop a career that offers both individual and company success; be part of an ownership culture that values diversity and where all colleagues are energized and engaged; and the ability to impact the health and lives of millions of people. Pfizer, a global leader in the biopharmaceutical industry, is continuously seeking top talent who are inspired by our purpose to innovate to bring therapies to patients that significantly improve their lives.
An opportunity is available for a highly motivated expert in advanced mass spectrometry of HLA-associated peptidomes to join a multidisciplinary group dedicated to understanding and predicting the immunogenicity of protein-based therapeutics. The Principal Scientist will establish the utility of a dendritic cell mass spectrometry (DC-MS) assay to detect peptides from therapeutic proteins that are processed and presented on MHC (major histocompatibility complex) class II for helper CD4 T cell recognition. With prior demonstrated expertise in the application of the DC-MS assay in the field of immunogenicity of protein therapeutics, the successful candidate will implement relevant bioinformatics tools that allow data mining for confident identification of peptide presentation. Alongside the application of the tool to our protein therapeutics portfolio and DC-MS data integration into portfolio decision making, the candidate in this position will work to further refine the technique. The Principal Scientist will join at the interface of predictive immunogenicity sciences and leading protein mass spectrometry analytics to become a key contributor to our efforts to rationally design low immunogenicity biomolecules.
