Bonus Qualifications 

  • Experience with stem cell isolation procedures 

  • Experience with Master Cell Bank release procedures for manufacturing purposes 

  • Experience in diverse cell line immortalization approaches 

  • Experience with copy number determination, integration site analysis and other methods for characterization of cell line stability 

  • Experience in handling multiple cell types and culture formats 

  • Experience in analysis and interpretation of “omics” technologies (next generation sequencing, transcriptomic analysis, metabolomics) 

  • Basic understanding of cell manufacturing and processes at scale 

  • Experience preparing regulatory submissions 

  • Flexibility and willingness to expand skill set and responsibilities 


Additional Information & Requirements

This is a full-time role based out of our Headquarters in San Francisco, CA. Scheduled work will primarily be during normal business hours however cell culture work requires a flexible schedule and working with team to respond to weekend and holiday schedules.
