  • Analyze data using tools such as FlowJo, Omiq, Microsoft Office, MacOS, and GraphPad Prism
  • Periodic data presentation
  • Lab preparation, organization and resource acquisition
  • Collaborating and coordinating workflow intra and interdepartmentally to keep antibody discovery pipeline on track

This role may be for you, if you:

  • Enjoy working in a collaborative and fast paced environment
  • Have a strong desire to develop your skills
  • Excel at maintaining experimental documentation, exhibit meticulous attention to detail
  • Have great oral and written communication skills, organizational skills, as well as good interpersonal skills
  • Are comfortable working in a dynamic environment where priorities can change from day to day
  • Self-starter with an ability to follow protocols, ask scientific questions, and adapt to evolving methods
  • Have an eye for detail and pride yourself on the quality of your work
  • Work on current problems while thinking of future solutions

To be considered for this role, you must have a minimum of B.S. in Molecular Biology, Cellular Biology or related field with 2+ years of laboratory experience. We would like someone with cellular biology lab experience, and basic laboratory animal handling experiences (mice). Experiences with immunofluorescence-based techniques, immunofluorescence cell staining, and knowledge of immunology are preferred.  Experience with flow cytometry is a plus.
