Ambrx, Inc. is a biopharmaceutical company with a mission to deliver breakthrough protein therapeutics. Ambrx is based on a fundamental advance in protein biosynthesis that enables the company to genetically engineer proteins with new amino acid building blocks beyond the common twenty, enabling the biosynthesis of proteins with new physical, chemical and pharmacological properties. At Ambrx, we are dedicated to assembling and developing an exceptional team and a breakthrough technology to create the next generation of protein-based medicines.

 

Ambrx is seeking an experienced and highly motivated Toxicologist to join the Preclinical Science group in our fast-paced and dynamic organization. The successful candidate will play a key role in setting safety pharmacology strategy, designing and executing tolerability and toxicokinetic (TK) studies, overseeing drug metabolism (DM) studies, and supporting pharmacokinetic (PK) studies and modeling as appropriate to help progress novel protein therapeutics from preclinical research into IND enabling studies.

 

Primary Responsibilities:

Responsible for all aspects of Toxicology and DMPK functions:

  • Design, outsource, and manage non-GLP and GLP toxicology and safety pharmacology studies in support of projects from discovery to early clinical development.
  • Prepare study protocols and reports related to toxicology studies.
  • Interpret study results from toxicology in conjunction with DMPK and pharmacology studies to estimate therapeutic index.
  • May perform/oversee/outsource pharmacology, DMPK studies, PK/PD modeling for dose predictions and/or candidate selection as appropriate.
  • Lead early hypothesis-driven investigations into mechanisms of toxicity for the proactive management of potential safety liabilities.
  • Communicate study status, timelines and data to key stakeholders.
