  • Help define structure and quality standards for the client's dataset pipeline
  • Participate in expert discussions, interviews, and research engagements
  • Have hands-on, non-administrative preclinical R&D experience at a company that develops its own drug assets in-house and has taken programs to the clinic — Must Have
