  • Conduct in vitro discovery campaigns utilizing phage display technology.
  • Lead campaigns involving display and single B-cell platforms for mAb and peptide discovery.
  • Develop strategies to amplify and clone antibody variable regions, protein domains, or peptides from display libraries into final therapeutic formats.
  • Manage collaborations with external partners, including contract research organizations (CROs), and build workplans for synthetic library generation and animal immunizations.
  • Leverage your leadership skills to co-lead core discovery teams and represent Protein Engineering at project team meetings.
  • Maintain laboratory stocks and reagents, mentor junior staff, and maintain accurate electronic laboratory notebooks.
Requirements and Qualifications
  • A PhD in Molecular Biology, Biochemistry, Microbiology, Structural Biology, or related field.
  • 7-10 years of experience in antibody discovery teams within the pharmaceutical or biotechnology industry, or 4-7 years with a Master's degree.
  • Firsthand experience in mAb discovery platforms, such as display and single B-cell technologies.
  • Experience with prokaryotic or eukaryotic display technologies.
  • Expertise in molecular biology techniques, including PCR, cloning, primer design, plasmid preparation, and cell culture handling.
