Postdoctoral Fellow- Biological Chemistry, Kirchhofer lab

Genentech
United States, California, South San Francisco
Jan 06, 2026
The Position

A healthier future. It's what drives us to innovate. To continuously advance science and ensure everyone has access to the healthcare they need today and for generations to come. Creating a world where we all have more time with the people we love. That's what makes us Genentech.

The Opportunity

We are seeking a highly motivated postdoctoral fellow to join the laboratory of Dr. Daniel Kirchhofer in the Department of Biological Chemistry at Genentech. This position offers an exciting opportunity to use state-of-the-art peptide display technologies - including phage and mRNA display of macrocyclic and cystine-knot peptide libraries - to discover peptides that modulate the function of therapeutically relevant protein targets. A major focus will be on members of the type II transmembrane serine protease family, cell-surface enzymes implicated in disease processes such as viral entry. In parallel, you will engineer disulfide-constrained peptide libraries designed to engage challenging, flat protein-protein interfaces, using a newly developed scaffold with a unique surface topology, and will leverage machine-learning-assisted methods for peptide sequence optimization. To elucidate mechanisms of peptide activity, the successful candidate will apply a broad range of biochemical, biophysical, structural, and cellular methods.

The ideal applicant is an independent, creative scientist who thrives in a collaborative, team-oriented environment. The position offers extensive opportunities to interact with the vibrant Genentech postdoctoral community as well as scientists across multiple departments.

Who You Are:

A Ph.D. in biochemistry, biophysics, structural biology or related discipline and a proven record of productivity in their graduate career as demonstrated by first-author publications.

Preferred Qualifications:

  • Strong experience in molecular biology

  • Expertise in engineering, expressing and purifying proteins

  • Experience with directed evolution (yeast, phage, mRNA display, etc.) is preferred

  • Experience in peptide chemistry is a plus

  • Proficiency in surface plasmon resonance or biolayer interferometry

  • Proficient in structural biology (crystallography and or cryo-EM) is a plus

  • Experience with tissue culture, cell-based assays

  • Strong analytical, collaborative, communication and organizational skills
