Possible temp to perm position – possible

The Cell Line Development Group in South San Francisco, CA is seeking a Scientist I/II to join a talented and collaborative team developing CHO cell lines for GMP applications.

• In this laboratory position the candidate will perform hands-on CHO cell line development and characterization studies in a well-supported and dynamic environment to help advance novel biotherapeutics into human clinical studies.
• The work will encompass molecular, cellular, and bioprocess development studies relating to the generation and characterization of optimized CHO cell lines for production of our cancer pipeline candidates.

Key Responsibilities:

• Perform CHO cell line development, including transfection, selection, single cell subcloning, growth and productivity screening, cell banking and stability assessment of cell banks.
• Design and generate DNA vector constructs for protein?including monoclonal antibodies and antibody-like molecules)
• Culture mammalian cells across multiple scales and formats, from 96-well plates up to shake flasks.
• Operate instruments like ViCell automated cell counter, Octet, Clone Select Imager, microscope, HPLC, ambr15, Beacon and flow cytometer. Share responsibility for equipment maintenance.
• Perform genetic characterization of cell banks using molecular techniques like DNA sequencing and PCR.
• Review DNA sequencing data (including NGS), Southern/Northern blots, quantitative PCR results.
• Author and review cell line development technical reports that meet expectations of regulatory agencies for all stages from IND to BLA.
• Present updates at cross-functional meetings and collaborate closely with cell culture, purification, analytical and formulation development colleagues to meet project timelines.
• Actively seek opportunities to optimize or enhance the cell line development workflow.
• May publish or present scientific findings in peer-reviewed journals, internal or external conferences or consortia.
• Display effective organization, verbal and written communication skills, and adherence to good documentation practices.

Qualifications
