AlivaMab Discovery Services is a rapidly growing leader in the discovery of human antibody therapeutics, trusted by top-tier pharmaceutical and biotechnology companies to deliver panels of drug-quality human antibodies. We deliver on our partners' design goals, from simple to extraordinarily challenging, through collaborative access to our scientists' creativity and experience combined with proven technologies, including the AlivaMab® Mouse suite of transgenic mice. We excel in the rapid and efficient delivery of molecularly diverse therapeutic antibody candidates, well-characterized for function, kinetics and developability, with expanded capabilities for engineering of alternative formats, including multispecifics and CARs. Our organization is dedicated to creating a healthier world through partnerships that bring better medicines to patients faster, and we recognize our success starts with hiring people who share our passion for science.


  • Design and conduct small to mid-scale antibody purification by affinity, ion-exchange and other chromatographic methods from hybridoma and recombinant expression
  • Perform protein characterization for quality control and developability assessment to assess stability, purity, polyspecificity and other biophysical properties
  • Develop purifications methods for difficult-to-handle antibodies and optimize platform processes for higher production yields and product stability
  • Support developing automated high throughput purification workflows
  • Assist with molecular biology workflows and transient expression of antibodies using mammalian expression systems, as needed
  • Execute projects and prepare written reports
  • Experimental design, experiment execution and troubleshooting
  • Work closely with other team members and leaders.
  • Effectively present and communicate concepts and results, both orally and in writing, to colleagues and management.


Key Skills and Requirements:


  • Bachelors in Biology, Chemistry, Biochemistry, or other disciplines required (Masters & beyond, preferred) with a minimum of 3+ years of related experience in industry
  • Strong knowledge of and skills in purification and analytics, specifically antibodies and various antibody formats
  • Extensive experience using Protein A and ion exchange methods for antibody purification.
  • Experience with purification instrumentation such as AKTA or similar
  • Experience with SDS-PAGE, SEC-HPLC, SEC-MALS and mass spectrometry-based methods for antibody analysis. Familiarity with hydrophobic ion exchange chromatography and polyspecificity characterization
  • Experience with molecular biology techniques (PCR, DNA/RNA isolation, plasmid prep, gel extraction, cloning, Sanger sequence analysis)
  • Ability to multitask
  • Excellent trouble shooting and problem-solving capabilities
  • Extraordinary attention to detail, planning skills and organizational skills
  • History of timeline-driven delivery
  • Outstanding oral and written communication skills
  • Independent and creative researcher who demonstrates initiative
