Associate Principal Scientist, Materials and Biophysical Characterization Full-time

Associate Principal Scientist

The Materials and Biophysical Characterization group in the Pharmaceutical Analysis and Digital Technologies organization is seeking a highly self-motivated and innovative scientist with deep knowledge and problem-solving skills in biotherapeutics characterization. The Materials and Biophysical Characterization team is responsible for building the mechanistic understanding of the interplay between formulation composition, stability, device, and process to ensure robustness and quality of drug substances and drug products in the biotherapeutics pipeline.

As an Associate Principal Scientist, you will be contributing to projects in a diverse biotherapeutics pipeline by developing and implementing biophysical and particle characterization tools and collaborating with process, formulation and device functions as part of the CMC development team. You are expected to use your scientific expertise to find creative solutions to challenging problems which require deep analytical insight and critical thinking. Additional responsibilities include authoring technical reports and regulatory documents, presenting technical data, and project management. You will have the opportunity to conduct independent research, publish research findings, present at scientific conferences, and engage with various external scientific societies/organizations. This is an excellent growth and learning opportunity to work in an exciting, collaborative environment with a wide array of scientists from different divisions and make significant contributions towards our life-saving medicines.
