Role Summary

Manufacturing Sciences and Technology (MSAT) at Pfizer is looking for a highly motivated, versatile candidate to join our multidisciplinary team of scientists and engineers in Andover, MA. The group supports Pfizer's portfolio of late stage development and commercial biopharmaceuticals and vaccines, and is responsible for process troubleshooting, process improvements and second- generation process development. We are looking for someone who is eager to contribute independent thinking and technical excellence to the upstream cell culture and fermentation team.

The ideal candidate will be a valuable contributor to the upstream team within MSAT Andover. The role is well-integrated with the rest of the MSAT group and will involve a lot of collaborative work both within the group and across the Andover site.

In this role, the candidate will be responsible for designing and execute bioreactor experiments in bench-top bioreactors and associated scale-down equipment with the goal of developing robust, scalable, and high productivity processes that produce biotherapeutics with appropriate product quality attributes to treat human diseases. The candidate will also collaborate with manufacturing operations in process improvement & robustness initiatives and technical investigations as a subject matter expert to ensure product supply. The colleague may also be involved in innovation and technology development projects that seek to improve production processes both from a process engineering as well as a biological perspective that have the potential to increase process performance.

  • Plan and execute upstream process experiments at benchtop scale.
  • Participates and significantly contributes to discussions in lab and project team meetings on design of experiments (bioreactor and shake flask) and interpretation of experimental data.
