Scientist: Medicinal Chemistry - Contract - San Francisco, CA

Are you ready to turn precision into progress and play a key role in shaping the future of pharmaceutical innovation?

Proclinical is seeking a talented and passionate Medicinal Chemist to join our small-molecule drug discovery team.

Primary Responsibilities:

In this role, you will contribute to advancing science and developing life-changing medicines. You will contribute to all stages of drug discovery, from hit identification to lead optimization, within a collaborative and fast-paced environment.

Skills & Requirements:

  • Education and Experience:D. in Organic Chemistry alongside 6+ years experience, or equivalent experience in chemical research, preferably within a biotechnology or pharmaceutical setting.
  • Expertise in Synthetic/Medicinal Chemistry: Proven expertise in modern synthetic organic chemistry, demonstrated by a strong track record of at least one first-authored publication(s) and an understanding of medicinal chemistry principles.
  • Drug Discovery Acumen: You have experience in the drug discovery process from hit identification, hit-to-lead, and lead optimization.
  • Structure-Based Drug Design: Experience with structure-based drug design is highly preferred.

The Scientist's responsibilities will be:

  • Drive Drug Discovery Programs: Contribute to the chemistry efforts for one or more drug discovery programs, focusing on designing drug-like molecules and optimizing compounds towards drug development candidate selection.
  • Collaborate Cross-Functionally: Work closely with a diverse range of functions, including Drug Metabolism and Pharmacokinetics, Structural Biology, Biochemical and Cellular Pharmacology, Machine Learning, Pharmaceutical Sciences, Safety, and disease area Biology.
  • Design and Synthesize Novel Compounds: Apply innovative structure- and computationally-driven, as well as property-based design principles, to design and/or synthesize analogs for molecular targets. This includes conducting multi-step syntheses, retrosynthetic analysis of complex molecules, and troubleshooting synthetic issues internally or with CRO partners.
  • Analyze and Interpret Data: Utilize strong analytical thinking skills to organize and analyze structure-activity relationship (SAR) data sets to drive design ideas and impact program direction.
  • Solve Complex Problems: Design compounds that effectively address challenges related to potency, physical properties, and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity).
  • Support Chemistry Operations: Execute synthesis within internal laboratories, collaborate with Contract Research Organizations (CROs), and provide broad general chemistry department support.
  • Communicate and Present: Deliver effective presentations and articulate scientific findings clearly to both internal and external stakeholders

Compensation:

  • $70 to $80 per hour.
