Job Description

Be a part of the legacy: Postdoctoral Research Fellow Program

Our Research Laboratories’ Postdoctoral Research Fellow Program aims to be a best-in-industry program for industrial postdoctoral researchers, designed to provide you with an academic focus in a commercial environment. With the resources, reach, and expertise of a large pharmaceutical company, postdoctoral researchers will be positioned to excel in an institution committed to breakthrough innovation in research and discovery.

Attention NJ Applicants: In April 2020, our Company announced plans to consolidate our New Jersey campuses into a single New Jersey headquarters location in Rahway, NJ by 2023. Therefore, the NJ work location for this role will be temporarily based and the exact timing of the departmental move to Rahway, NJ will be communicated at a future date.

Position Overview:

The Sterile and Specialty Products group is responsible for developing parenteral dosage forms for small, intermediate, and large molecules from preclinical toxicology studies through commercialization. Our development teams ensure robust composition, primary packaging/device, and process selection through deep fundamental understanding and product characterization. We leverage smart experimental design, cutting edge analytical tools, and predictive approaches to inform molecule, formulation, and process selection.

We are seeking a highly motivated Postdoctoral Fellow to lead the development of a novel workflow for rapid identification of viscosity-reducing formulation compositions at high protein concentrations. Specifically, the Fellow will use computational and analytical tools to elucidate the relative contribution of protein hotspots toward antibody solution properties as well as the link between hotspots and the ability of specific formulation components to mitigate protein-protein interactions and reduce viscosity. The data generated will be used to build a model to predict viscosity at high concentrations under specified formulation conditions for proteins with known sequence-structure properties.

The successful candidate will work across functions, gaining insight into biotherapeutic development, and must be able to collaborate in a fast-paced, interdisciplinary environment. The Postdoctoral Fellow is additionally expected to author scientific papers on their research and present novel findings at internal and external scientific meetings.

Responsibilities include but are not limited to:

  • Use modeling tools to identify structure-based molecular properties and predict protein behavior.

  • Characterize protein solution behavior.

  • Build and validate a model to enable prediction of protein solution behavior based on sequence-structure properties.

  • Work cross-functionally and lead/facilitate meetings with collaborators.

  • Publish results in peer-reviewed journals and present findings at internal and external scientific conferences.

  • Work cross-functionally and lead/facilitate meetings with collaborators.

  • Publish results in peer-reviewed journals and present findings at internal and external scientific conferences.

Education Minimum Requirement:

  • PhD in Chemical/Biomolecular Engineering, Bioengineering, Biophysics, Pharmaceutical Sciences, or a related field

  • Less than 3 years of postdoctoral experience or or will you have completed your PhD within the next year.

Required Experience and Skills:

  • Experience in protein solution characterization (i.e., rheology, DLS, etc.)

  • Ability to work both independently and collaboratively.

  • Strong written and oral communication skills and a proven track-record in scientific publications and presentations

  • High flexibility and adaptability to further develop and learn new skills in a dynamic work environment.

  • A strong passion to drive cutting-edge science.

Preferred Experience and Skills:

  • Experience in application of molecular modeling software for protein design and characterization (i.e., Rosetta, MOE, Schrodinger, Gromacs, etc.).

  • Experience in protein engineering and/or site-directed mutagenesis.

  • Experience in protein biochemical and biophysical characterization techniques such as SEC, IEX, MFI, and DSC.

  • Knowledge or experience in structural elucidation techniques such as NMR, protein crystallography, Cryo-EM, and/or MS.

  • Understanding of Statistical Thermodynamics and Hydrodynamics principles applied to biomolecules, polymers, or colloids.

  • Experience handling and processing large experimental and computational data sets for model training and validation.

  • Experience in machine and deep learning methodologies.

  • Proficiency in Python, R, or Matlab programming.
