We are searching for the best talent for a Senior Scientist, Protein Formulation to be located in Malvern, PA.

Purpose: Drug Product Development and Delivery (DPD&D) is responsible for formulation, process, device development, and clinical manufacturing of biotherapeutics. The Senior Scientist position within Protein Formulations group in DPD&D will be a lab-based role, responsible for experimental studies in pre-formulation, formulation, and analytical development of therapeutic proteins (mAbs, bispecifics and multispecifics) as well as bioconjugates. This includes development and optimization of the technical operations associated with biologics development, high concentration feasibility, excipient screening, diluent compatibility/administration assessment, and stability campaigns. The scientist will work independently as well as with cross-functional teams to support project needs and meet project deliverables.

You will be responsible for:

• Designing and performing formulation screening, characterization, and stability studies to support early and late-stage product development.
  
• Developing and implementing chromatographic, biophysical, and analytical methods to characterize structural attributes, stability, and degradation mechanisms of bioconjugates and their individual components (e.g., linker, payload, antibody).
  
• Collaborating with Discovery and Development teams to identify molecule and formulation related challenges in protein and bioconjugate development and develop appropriate drug product presentation and risk mitigation strategies.
  
• Collecting, analyzing, interpreting, and documenting experimental data, and communicating the results effectively to project teams, cross-functional partners, and senior leadership.
  
• Authoring and reviewing technical documentation, including study protocols, technical reports, and technology transfer documents to support drug product manufacturing.
