Principal Scientist-process Development

Pfizer Pfizer · Pharma · CT

Seeking a Principal Scientist with expertise in enzymatic peptide synthesis and biocatalysis for innovative process development in peptide and API manufacturing. Requires a PhD and strong experimental skills, with industry experience preferred. Role involves designing, optimizing, and scaling enzymatic processes, collaborating cross-functionally, and contributing to scientific innovation.

What you'd actually do

  1. Independently design, develop, and optimize enzymatic platforms, protocols, and workflows for peptide bond formation and related transformations.
  2. Evaluate and integrate emerging technologies in peptide synthesis and biocatalysis to meet process chemistry and manufacturability targets.
  3. Conduct enzyme screening campaigns, reaction optimization, and scale‑up to support development through late‑stage research and process transfer.
  4. Independently plan and execute experiments with well‑defined objectives, robust controls, and quantitative data analysis.
  5. Maintain high‑quality experimental records in electronic notebooks in full compliance with internal and regulatory expectations.
