Full time

Crinetics Pharmaceuticals is seeking an experienced scientist to join its growing and dynamic development team. This individual will be responsible for the management of outsourced bioanalysis and biomarker activities including assay selection, development, validation, and utilization in nonclinical and clinical development.  The work will support projects at various stages of development thereby allowing the selected candidate to play an active role in our drug discovery and development efforts to advance small molecule therapeutics for rare endocrine disorders and endocrine-related cancers. This is a unique opportunity to work with a proven and well-funded drug discovery and development team in a small company environment in the heart of San Diego’s biotechnology community. (Position will be filled at level commensurate with experience.)


These may include but are not limited to:

  • Contribute to translational PK/PD strategy to support the clinical development plan and program goals.
  • Derive a First-In-Human maximum recommended starting dose and pharmacologically active dose based on well established in vitro to in vivo and/or allometric scaling approaches.
  • Predict human exposure (PK) and pharmacodynamic (PD) biomarker-based response for early clinical trials.
  • Based on the animal model data and early clinical trials, explore mechanistically the effects on target and pathway to understand the requirements for demonstrating efficacy in human.
  • Drive learning through back translation of early clinical PK/PD data and providing prioritized future options for clinical testing.
  • Provide translational PK/PD expertise to the project team and closely collaborate with in vivo Pharmacology and Clinical Sciences.
  • Identify, develop, and implement new ideas based on PK/PD data analysis outcomes.
  • Lead the collaborative with team members and consultants/vendors to execute appropriate PK-PD analysis.
