Position Summary

We are seeking a highly motivated and experienced Senior Scientist with expertise in developing cell-based lot-release potency assays for gene editing materials used in cell therapy, including mRNAs and viral vectors. In this hands-on role, the successful candidate will lead the conceptualization, optimization, qualification, and transfer of potency assay methods to quality control (QC) labs. The ideal candidate will also have strong scientific and technical experience in gene editing applications, such as CRISPR, as well as analytical method development experience within a CMC environment.

Key Responsibilities

  • Design, develop, and optimize QC-compatible analytical methods and potency assays (eg. flow cytometry, ELISA, cell-based reporter gene assays, qPCR/dPCR, capillary electrophoresis) to support release and stability testing of gene editing materials such as mRNAs and viral vectors.
  • Identify and manage critical reagents needed to develop, execute and transfer analytical methods.
  • Collaborate with QC to ensure smooth analysts training and transfer of assays for lot release and stability testing.
  • Design, engineer and maintain immortalized monoclonal cell lines, including reporter gene constructs, to support the development of MOA reflective potency assays.
  • Author and/or review technical documents for method development, transfer, qualification protocols and reports.
  • Implement statistical tools and design of experiments (DOE) to ensure robustness and reliability of assays.
  • Act as subject matter expert (SME) in analytical subteam meetings and cross-functinoal meetings (eg. QC, AS&T, CMC, Regulatory etc.).
  • Evaluate new and innovative technologies for implementation into AD and QC.
  • Maintain compliance with internal quality systems and relevant regulatory guidelines.

Qualifications & Experience

  • MS with 6+ years, or PhD with 3+ years in analytical development, ideally in the gene therapy space.
  • Proficiency in a broad range of analytical techniques used in cell and gene therapies, such as qPCR/dPCR, Flow Cytometry, ELISA, protein electrophoresis, plate-based reporter gene assays.
  • Good understanding of ICH guidelines for assay qualification/validation.
  • Ability to align method development with the program goals and requirements in a phase-appropriate manner.
  • Extensive experience in gene editing application especially newer generations of CRIPSR editors is preferred.
  • Experience collaborating across CMC functions (PD, QC, AS&T etc.) is preferred.
  • Basic understanding of method lifecycle management from development to validation and beyond is preferred.
