The successful candidate will focus on cell line engineering and gene editing for the development of novel gene-editing technologies to advance our in vivo and ex vivo therapeutic programs.


  • Perform routine cell culture of adherent and suspension cell lines to support cell line engineering

  • Engineer mammalian cells by introducing plasmid DNA, mRNA, gRNA and Cas9 RNP by appropriate methods, including cationic lipid-based transfection and electroporation

  • Perform routine molecular biology techniques employing engineered cell lines to support development of next-generation sequencing (NGS) assays for sequence determination and assessment of on-and off-target DNA editing

  • Apply standard biochemical and immunological techniques, including protein extraction, protein gel electrophoresis, conventional and capillary western blotting, ELISA, and flow cytometry

  • Perform standard molecular biology techniques including DNA extraction, RNA extraction, and PCR

  • Work under the direction of a Research Scientist and across other platform technology and therapeutic groups to achieve desired goals

  • Maintain detailed records and tracking of engineered cell line production and inventory

  • Communicate key findings with internal and external partners by written reports and oral presentations

Minimum Qualifications

  • BS degree in Molecular Biology, Cell Biology, Biochemistry or a related discipline, and 3+ years of relevant research experience, or MS degree in a similar field and 1+ year of research experience obtained through industry co-op/internship and/or thesis-related research

  • Proficiency with mammalian cell culture techniques, including maintenance of adherent and suspension cell lines, transfection, cell counting, and standard cellular assays

  • Proficiency with standard molecular biology techniques (isolation of DNA and RNA, PCR, ddPCR, gel electrophoresis, oligonucleotide primer design)

  • Experience with routine biochemical and immunological methods (protein extraction, western blotting, flow cytometry, ELISA)

  • Working knowledge of CRISPR/Cas gene editing in mammalian cells

  • Demonstrated ability to work collaboratively with peers and effectively in a team-oriented environment

  • Superior attention to detail and organizational skills

  • Excellent oral and written communication skills

Preferred Qualifications

  • Experience with culturing primary human cells
