The Cell Line Development Scientist will lead initiatives to develop stable cell lines and cell pools to express novel envelope proteins to support GMP manufacturing of potential vaccine candidates.  This position will conduct and document laboratory experiments which trace the generation of a sequence from receipt to incorporation into an expression vector and optimization for expression in a cell platform which is used to express GMP compliant recombinant vaccine candidates.  




  • Lead the development of cell lines and efforts to identify optimal pools or lines which express recombinant vaccine meeting specifications determined by research and development teams within the DHVI as well as our collaborators.
  • Contribute new approaches to the development of methods for protein expression.
  • Perform transfection of mammalian cells using expression vectors engineered to express novel vaccine candidates.
  • Perform cell culture and passage in selection media to eliminate low and non-expressing cell populations.
  • Monitor cell pools and cell lines for cell density, viability and doubling time.  Interpret those results to determine sub-culture times and future strategy to optimize culture growth and expression.
  • Determine and optimize cell culture media and feeding strategies for long-term cultures.
  • Derive and characterize stable cell lines.
  • Sort cell populations using a cell sorter and sorting software.
  • Perform limiting dilution cloning to establish cell clones.  Operate CloneSelect and ClonePix to identify individual cell populations.
  • Develop collaborations with external organizations and provide support for development activities.  Work closely with analytical development functions to understand how the expressed product impacts product quality.
  • Maintains detailed records carefully documenting all process steps and reagents used under good documentation practices.  Maintains required laboratory supplies, reagents and consumables by ordering and tracking inventory.
  • Oversees and directs production and manufacture of master cell banks either in-house or by contract research organizations.
  • Directs release and characterization testing of master cell banks, including testing for adventitious virus testing to ensure compliance with FDA and EU standards.
  • Analysis and interpretation of data.  Assess and draw conclusions regarding progress and results of work, utilizing the data in appropriate decision making.
  • Mentors others in developing scientific skills and methods and may manage staff.
  • Perform other duties as assigned by DHVI leadership.
