Ambrx®, Inc. is an established biopharmaceutical company with a mission to deliver breakthrough protein therapeutics using an expanded genetic code. Unlike conventional conjugation techniques that create a mixture of suboptimal molecules, Ambrx technology combines site specific conjugation with proprietary linkers, payloads, and pharmacokinetic extenders to create a single molecular species that is optimized for safety, efficacy, and biophysical properties. We call this process Protein Medicinal Chemistry™.


Ambrx is seeking a highly motivated Research Associate/Senior Research Associate to be a key member of the Analytics and Formulations team in a fast-paced and dynamic organization.  The successful candidate will be responsible for performing routine analysis, data compilation, interpretation and presentation of results for analytical and formulation development, characterization, and stability studies.

Major Responsibilities:

  • Contribute to the design and conduct analytical method development experiments for complex protein biomolecules (including E. coli, yeast, CHO derived proteins/antibodies and ADC) and related impurities; preliminary qualification of these test methods for protein therapeutic candidates in pre-clinical and early-phase clinical development.
  • Characterize proteins and impurities utilizing conventional analytical techniques and specialized biophysical methods to understand degradation pathways and improve protein stability.
  • Write standard test methods, qualification protocols and reports, and trend stability data.
  • Summarize, interpret, and critically evaluate analytical data. Present results at Group/Team meetings.
  • Provide analytical support for upstream, downstream, conjugation process development, and analytical method transfer to CMOs.
  • Present analytical/stability data to cross functional project teams, coordinate resources within the analytical group to meet project goals and timelines.
