  • Quality and compliance: Familiarity with good documentation practices and maintaining an organized lab environment to support data integrity and compliance expectations.
  • Strong hands-on experience with LVV analytical assays, including cell transduction, flow cytometry-based functional titer, and genetic payload quantification (dPCR/qPCR).
  • Experience with ligand-binding assays (e.g. ELISA, MSD) for protein quantification and/or residual impurity testing.
  • Prior exposure to method development/optimization, qualification, and technology transfer in a developmental environment.
  • Familiarity with data integrity expectations (traceability, controlled documentation) and partnering with QC teams.
  • Ability to troubleshoot analytical methods using a data driven approach with appropriate escalation and documentation.
  • Experience supporting lentiviral vector drug product characterization, including in vivo or translational studies.
  • Comfortable working in a fast-paced environment, balancing short-term execution with longer-term assay/platform improvement.
