Inhibrx Inc.
La Jolla, CA

Identify, test, and characterize therapeutic antibodies against bacterial pathogens to be used in the development of antibody-based biotherapeutics to treat many of the most dangerous and clinically relevant bacterial and viral infections. Specific duties of the position include:

  • Grow bacterial cultures and extract genomic DNA to clone out DNA sequences of various virulence factors;
  • Perform titers on the serum of immunized llamas to check for the presence of single domain antibodies that bind targets of interest;
  • Make yeast libraries;
  • Sequence sorted yeast and analyze sequences to identify unique VHH antibodies;
  • Culture various strains of bacteria to the necessary growth phases under different conditions to use during binding/blocking assays;
  • Perform binding assays to identify antibodies that bind targets of interest;
  • Perform blocking assays to identify antibodies that block whole bacteria or pathogenic components from binding to their targets in humans, and to identify antibodies that block the toxic effects of whole bacteria or toxins secreted by bacteria;
  • Perform random mutagenesis to affinity mature antibodies from the yeast library;
  • Introduce point mutations through PCR, Gibson Assembly, and cloning;
  • Design and engineer various combinations of VHHs that enhance the valency, specificity, and affinity of multivalent, single-domain antibodies against multiple targets of a pathogen; and
  • Perform binding, cytotoxicity, and cellular assays on all new, optimized antibodies.

Minimum Requirements:
Master’s degree in biology, biochemistry, cell biology, or a related field, plus knowledge that can be gained through graduate level coursework or work experience to include experience in a wet lab; sterile techniques handling pathogenic microorganisms; culturing and discovering, testing, and optimizing antibodies against pathogenic bacteria; research techniques involving the virulence factors of opportunistic pathogens; cloning, ELISAs, Western Blots, protein purification, and gel electrophoresis; bacterial assays; and spectrophotometry to measure bacterial concentrations.

Klaus W. Wagner, M.D., Ph.D.

Klaus leads the clinical translation of Inhibrx’s biotherapeutic pipeline. Prior to joining Inhibrx, Klaus trained at M.D. Anderson Cancer Center as a fellow and worked at Banner M.D. Anderson Cancer Center as a medical oncologist, where he also served as the local principal investigator of cancer immunotherapy trials. Klaus’s scientific work at Genentech and the Genomics Institute of the Novartis Research Foundation (GNF) focused on drug discovery and predictive biomarker development. Klaus received the highest academic honors and was a Scholar of the German Merit Foundation. He received his M.D. and Ph.D. from the Friedrich-Alexander University of Erlangen in Germany.

Quinn Deveraux, Ph.D., Founder

Quinn leads the target identification, validation and therapeutic lead selection and oversees the development strategy for Inhibrx’s biotherapeutic pipeline. Prior to founding Inhibrx, he spent 10 years at the Genomics Institute of the Novartis Research Foundation (GNF). Quinn lead groups of Ph.D./M.D. level investigators in the conception and development of novel target identification and validation platforms. Quinn lead the first therapeutic antibody from GNF to transition from bench-top to clinical trials. His research on cell death at the Stanford-Burnham-Prebys Medical Discovery Institute was highly cited. Quinn received his Ph.D. in biochemistry from the University of Utah School of Medicine.

Brendan Eckelman, Ph.D.

Brendan is a co-founder of Inhibrx and serves as its Chief Operating Officer and VP of Biotherapeutics. Brendan heads research, overseeing several key functional areas spanning discovery to therapeutic development. In addition, he has critical responsibilities in corporation strategy and operations.
