About this position
Postdoctoral Research Fellow, BioMedicine Design at Pfizer in San Diego, California, United States.
This is a postdoctoral opening in Pfizer’s BioMedicine Design (BMD) / Biotherapeutics Discovery group focused on developing a next-generation T cell engager (TCE) to improve tumor selectivity and reduce on-target, off-tumor toxicity. The role sits at the interface of protein engineering, cell biology, immunology, and oncology, with opportunities to work on antibody discovery and engineering, cellular assays, and preclinical evaluation.
The postdoc will design and produce constructs, develop and use cell-based assays, perform literature-driven hypothesis generation, and communicate results in internal meetings. The program is intended to train the fellow in therapeutic discovery and modality selection, with the goal of preparing them for early-stage drug discovery work and publication in high-impact journals.
Eligibility highlights: PhD in cancer biology, immunology, molecular/cellular biology, biochemistry, chemical and biomolecular engineering, or a related field; less than 2 years of postdoctoral experience; at least one first-author research article; strong hands-on experience with molecular cloning, recombinant protein expression/purification, mammalian cell culture, cell line engineering, transfection, cell-based assays, and flow cytometry. Two recommendation letters are required, including one from the PI and one from an additional professor.
Funding and terms: full-time fixed-term fellowship for 2–4 years. Salary is listed at $64,600–$107,600 annually, plus a bonus target of 7.5% and comprehensive benefits. Relocation assistance may be available. The role is on-premise.
Application window: apply by 2026-10-13. U.S. work authorization is required and visa sponsorship is not available.
