The Senior Scientist in the Large Molecule Drug Product Development will be a lab-based role, responsible for experimental studies in pre-formulation, formulation, characterization and analytical development of therapeutic proteins or other biologics including monoclonal antibodies (mAbs), bispecific, fusion proteins, virus like substances, RNA therapeutics, gene therapy and mixed conjugates. This includes development and optimization of the technical operations associated with liquid and lyophilized biologics development, diluent compatibility/administration relevant studies and stability campaigns. In addition, biophysical/analytical method development and data interpretation to analyze different biologics modalities is required.

Major Duties And Responsibilities To Include:

Design and execute formulation development experiments for large molecule drug products such as gene therapy, viral vector products and RNA therapeutics as well as other biologic drug candidates (including vaccines and monoclonal antibodies),

Rational formulation design/selection and characterization studies relevant to the stage of development. Studies include, but are not limited to, biophysical characterization, stability, composition selection and robustness and development of administration protocols.

Design and execute process development studies to determine and characterize process parameters associated with preparation of drug products for RNA therapeutics, gene therapy and viral vectors, and other biologic drug products. Studies include, but are not limited to, freeze-thaw, mixing, filtration, pumping, filling, biophysical characterization, stability, composition robustness and lyophilization.

Development of analytical and characterization methods to support drug product development.

Design and execute studies to understand how the drug product interacts with the product contact material surfaces during fill/finish manufacturing and during dosage preparation.

Development and optimization of liquid and lyophilized biologics formulations, as well as execution of characterization plans and stability studies

Design and execute compatibility studies to support administration of large molecules

Design and manage stability studies on target and experimental formulations

Perform technical analysis of the project data, including trending of data.

Author technical reports and present data to peers and functional management

Follow general laboratory safety procedures, as related to biologically-derived materials

Collaborate with functional line management as well as scientists in related functional areas such as Research and Development, QC/QA, Clinical, Manufacturing, Toxicology, and Regulatory (CMC)
