Job Details

Regeneron seeks a highly motivated and passionate scientist to join our Analytical Sciences Bioassay Development team specializing in Cell and Gene Therapy (CGT) programs. As a subject matter expert and leader in the lab, you will work closely with our Research and Development teams to support the Manufacturing, Process Sciences (PS), Quality Control (QC), and CRO/CDMO partners through the development, optimization, characterization, qualification, and transfer of binding and cell-based potency assays across a wide range of novel modalities for Regeneron CGT programs. 

As an Analytical Scientist in the Bioassay Development group, a typical day might include the following:

  • Collaborate with partner groups in research to bring in-house, develop, and optimize analytical methods to evaluate potency of novel CGT candidates using a combination of binding and cell-based assays for eventual transfer to GMP testing groups.
  • Stay at the leading edge of industry trends and agency requirements in the CGT potency assay space as it pertains to development and transfer in the GMP environment.
  • Proactively engage and lead troubleshooting activities for established potency methods by providing scientific support across the program life cycle.
  • Independently create scientifically sound project development plans and relevant experiments using high-level project timelines and goals.
  • Interpret data and analyze results to design follow-up experiments needed to complete assay development. Present results to management and at cross-group meetings.
  • Write and review assay development and qualification protocols and reports, SOPS, technical documents, investigation summaries, and IND/BLA submission sections.
  • Use statistical tools to develop quantitative measures in decision making around assay development and performance.
  • Use scientific literature to develop scientific arguments for white paper justifications, investigation conclusions, new technology, and process improvements.
  • Produce and maintain accurate records.
  • Represent group as SME on internal and external project teams.  Serve as scientific lead for potency at partner CRO/CDMOs.
  • Train junior level group members and act as a mentor within the laboratory.

This role might be for you if:

  • You are able to comfortably work in a dynamic, fast-paced, closely collaborative environment, on multiple projects in parallel, independently or as a group.
  • You are self-disciplined and proactive in your approach to meeting established projects goals.
  • You are detail-oriented, eager to learn and implement new ideas and techniques, and lead multiple projects in a team-based environment.
  • You have excellent verbal, written, presentation, and interpersonal communication skills.
  • Have an interest in leading project teams composed of junior staff.
  • You're interested in developing into a mentor and leader within the group.
