Development Scientist I, Analytical Development and Quality Control
New Haven, CT - USA
Job Summary
This role focuses on the analytical characterization of biotherapeutics from clinical through commercial stages with a strong emphasis on antibodies proteins and peptides. The work involves applying a range of analytical techniques for size and charge variant analysis and interpreting protein post-translational modifications and their impact on biological function. A key expectation is the ability to independently design and generate procedures protocols and reports for protein forced degradation studies fractionation studies comparability assessments and critical quality attribute (CQA) evaluations. Additional responsibilities may include representing the group on cross-functional development teams as well as training and leading elected day-to-day activities of junior scientists. Ready to see how deep scientific rigor can directly influence patient outcomes
Accountabilities
In this position the Development Scientist I will perform enrichment fractionation and detailed characterization of protein variants including charge and size variants to support biotherapeutic development. The role includes designing and conducting experimental studies developing and optimizing analytical methods and delivering comparability and forced degradation studies that inform product understanding and control strategies. The scientist will summarize structurefunction relationship findings and author CQA reports that guide decision-making across development stages. Responsibilities extend to active participation in cross-functional development teams representing the Protein Characterization group and leading scientific and technical problem-solving efforts within the team. The role also includes authoring CMC sections for regulatory submissions technical reports department-specific protocols and reports and general operating procedures while driving the development and implementation of new procedures and work practices that improve analytical capabilities.
