We are seeking an innovative, collaborative and accomplished chemical biologist to support the discovery and optimization of our novel base editors. The ideal candidate will have extensive experience of molecular evolution techniques applied to the engineering and optimization of recombinant protein structures and functions.


Primary Responsibilities

  • Use molecular evolution, engineering, and structure-guided approaches to discover, and/or optimize base editor proteins. Examples include but are not limited to:
  • Engineer and/or optimize base editors to recognize specific target DNA sequences
  • Design and conduct evolution campaigns
    • Critically evaluate evolution outcomes and identify and validate positive hits
  • Optimize binding affinity and/or catalytic activity of existing editors
  • Validation and evaluation of candidate base editor’s activity in mammalian cell
  • High-throughput sequencing of mammalian cells treated with new base editor constructs and quantification of base editing efficiency
  • Analyze and process high-throughput sequencing of base editing in mammalian cells and design increased stringency into selection plasmids to select for desired outcomes
  • Communicate scientifically rigorous findings via verbal and written communications, visualizations, and presentations


  • A Ph.D. in Chemistry, Biochemistry, Chemical Biology, Synthetic Biology, Molecular Biology or equivalent and a minimum of two years of experience in protein engineering via molecular evolution.
  • Experience with designing evolution campaigns (e.g. selection plasmid design and construction of large plasmid-based base editor libraries)
  • Familiarity with plasmid mechanics (g. synthetic RBS modulation, promoter selection, etc.)
  • Experience with generating high efficiency, electrocompetent bacteria
  • Experience with creating bacterial gene knock-out lines is desirable
  • Experience with protein expression and purification is highly desirable
  • Experience with CRISPR/Cas9 proteins is ideal but not essential
  • Strong scientific background and publication record with proven high levels of performance
  • Ability to work independently while also building relationships with colleagues.
  • Ability to adapt to increasing scope and complexity of work.
