The Sr Associate Scientist's responsibilities will be:

  • Independently design, execute, and manage laboratory experiments involving:
    • Primary human immune cell isolation (e.g., PBMCs)
    • Cell activation, genetic modification (e.g., viral transduction)
    • Cell expansion and cryopreservation
  • Apply statistical and data visualization techniques to analyze results, assess process performance, and draw data‑driven conclusions.
  • Support process development and scale‑up efforts to translate benchtop cell culture workflows into manufacturing‑relevant processes.
  • Perform multi‑color flow cytometry and cell‑based assays to characterize cell therapy drug products and evaluate process performance.
  • Maintain accurate, complete, and compliant laboratory documentation in alignment with internal policies and regulatory expectations.
  • Contribute to daily laboratory operations, continuous improvement initiatives, and feasibility assessments for new process concepts.
  • Assist with laboratory equipment upkeep, safety practices, and general lab organization to maintain an efficient working environment.
