ROLE SUMMARY

You will join the Early Bioprocess Development (EBPD) effort to optimize and scale up virus production from mammalian cells to support vaccine development and clinical testing. Your primary responsibility is to produce a variety of viruses including BSL-3 level with decent titer and consistency at large scale using different vessels and technology. You will join a team to do production runs for different viruses with quality and lightning speed to meet timelines for different vaccine projects; purify, aliquot and curate viruses for clinical testing; develop and implement assays for in process samples; optimize large scale virus production runs in bioreactors; troubleshooting when unexpected results occur, collaborate with analytical team to generate QC report, keep batch record and QC documentation for different virus batches.

ROLE RESPONSIBILITIES
  • Join a team of scientists to produce different types of viruses with high titer and consistency at large scale using different host cells and vessels such as disposable bioreactors, wavebags, iCellis, CelCradle, cell factory, etc. to support viral vaccine development and clinical testing
  • Optimize cell culture and virus production using automatic bioreactors such as AMBR250 with DOE principle which focuses on characterization, scale-up, and demonstration of process robustness
  • Develop fast and high throughput in process assays such as molecular, biochemical, biophysical, or biological assays to characterize and improve virus product and upstream process
  • Produce viruses in both BSL-2 and BSL-3 level using either suspension cells or adherent cells
  • Purify, aliquot and curate viruses using different technologies for clinical testing
  • Generate and keep track of batch records for virus production runs
  • Keep track of virus QC reports, seed, passage history, sequence variation and other critical information
  • Maintain host cell culture and virus seed for different virus production runs
  • Collaborate with colleagues within EBPD including Upstream process development, Purification, Analytical, and Formulation Development groups
  • Evaluation and implementation of new technologies to improve virus production
  • Perform timely notebook entries and review for completed experiments.

QUALIFICATIONS

Must Have
  • MS degree in Virology, Chemical Engineering, Microbiology, Immunology, Cell Biology, or other related discipline with a minimum of 3 years of related virus production experience, BS degree with a minimum of 5 years related virus production experience in academia, a biotech and/or a pharmaceutical environment
  • Hands-on experience in mammalian cell culture and virus production using different vessels such as bioreactors, wavebags, iCellis etc.
  • Experience working with different types and strains of viruses
  • Experience in both suspension and adherent cell culture for virus production

Nice to Have
  • Experience to design experiments to optimize mammalian cell culture and virus production in bioreactors based on DOE principle
  • Experience with disposable bioreactor/AMBR/Perfusion/iCELLis/continuous processing is a plus
  • Experience in virus purification and analytics such as UF/TFF, ultracentrifugation, chromatography, HA assay, plaque assay, TCID/50, FFA, qPCR, flow virometry, etc.
  • BSL-3 lab experience and related regulatory knowledge such as GMP manufacturing considerations are preferred

Sunshine Act

Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
