Postdoctoral Scientist, Medicinal Chemistry

Eli Lilly Eli Lilly · Pharma · San Francisco, CA

Postdoctoral Scientist role in Medicinal Chemistry at Eli Lilly, focusing on designing and synthesizing novel drug targets to optimize potency and ADME properties. The role involves multi-step synthesis, purification, characterization, and troubleshooting of chemical reactions, with opportunities to develop synthetic methods. Collaboration within the scientific team and presentation of findings are key.

What you'd actually do

  1. Synthesize and design new medicinal chemistry targets that optimize potency, ADME, and physicochemical properties
  2. Plan and execute multi-step synthetic routes to access structurally complex targets, including ring systems, stereocenters, and diverse heterocyclic scaffolds relevant to drug discovery
  3. Purify starting materials, intermediates, and final compounds
  4. Characterize reaction components including starting materials and products by modern analytical techniques including LCMS, NMR, etc
  5. Troubleshoot and optimize challenging reactions, applying mechanistic reasoning and synthetic creativity to advance stalled or difficult transformations
