Job Description
ROLE SUMMARY
We are seeking a driven and accomplished postdoctoral fellow to join the Biophysics group within the Pfizer Oncology Research Unit (ORU) in La Jolla California. This role offers a unique opportunity to collaborate closely with the ADC Chemistry and Tumor Biology teams to advance innovative drug design in oncology.
Under the guidance of experienced mentors with strong academic credentials the successful candidate will operate with a high degree of independence to characterize drug-protein and protein-protein interactions using both labelled and label-free biophysical methods. Additional characterization may involve biochemical or cellular techniques contributing to a deeper understanding of molecular mechanisms in cancer therapeutics.
The preferred candidate is motivated talented and an innovative scientist with a passion for tackling complex challenges in both fundamental research and drug discovery. The ideal candidate will have a strong scientific background demonstrated expertise in biophysical binding methods and protein sciences and a proven track record of impactful contributions including publications in leading scientific journals.
This role involves close collaboration with chemists and biologists to deepen our understanding of drug targets and explore novel small-molecule drug modalities. Success in this position requires not only technical excellence but also a collaborative mindset and a drive to contribute to high-impact science.
ROLE RESPONSIBILITIES
Work under minimal supervision to characterize small molecule-protein interactions using label and label-free biophysical methods (SPR ITC DSF/ CETSA TR-FRET)
Regularly communicate data with multi-disciplinary teams as well as provide scientific insights into kinetics and thermodynamics of protein-ligand interactions
Display growing knowledge and understanding of other disciplines relevant to early-stage drug discovery
Identify and integrate emerging biophysical technologies to address challenges associated with novel targets/modalities
Translate results from structural biology experiments to elucidate cell-based mechanisms of action and support the design of small molecules
Present findings in high impact publications or conferences
BASIC QUALIFICATIONS
Ph.D. in Biophysics Biochemistry Structural Biology or closely related field
Successful record of scientific accomplishments evidenced by scientific publications and/or presentations with at least one first-author publication in a peer-reviewed journal
Willingness to make a minimum 2-year commitment
No more than 2 years of post-degree experience.
Demonstrated expertise in both label and label-free biophysical methods (SPR ITC DSF TR-FRET) for characterization of protein-ligand interactions
Hands-on experience in plate-based pharmacology assays
Experience in handling recombinant proteins as tools in biochemical or biophysical assays
Knowledge and understanding in the areas of enzymology mechanisms of drug action and structural biology
Outstanding publication record reflecting scientific drive and creativity across multiple disciplines
Excellent oral and written communication skills with advanced interpersonal skills to facilitate knowledge sharing and scientific discussions
PREFERRED QUALIFICATIONS
Experience in characterization of bifunctional modalities and bidentate interactions using biophysical methods is desired but not a must
Basic understanding of structure-activity relationships (SAR) pertaining to ligand optimization
Experience working collaboratively across biological and chemical discipline
