The opportunity

Anthropic's Life Sciences team is building a research group focused on biological discoveries by combining AI with hands-on biological research. We're seeking research scientists with deep medicinal chemistry expertise to join the team.

What you'll do

  • Design multi-step synthetic routes for small molecules and oversee their: execution end to end, including route selection, reaction optimization, purification strategy, and interpretation of full characterization data (NMR, LC-MS, HPLC)

  • Coordinate synthesis and biological evaluation with external contract: research organizations and academic partners

  • Evaluate AI-designed molecules and AI-proposed synthetic routes, drive them: to experimental readout, and feed results back to research teams

  • Apply medicinal chemistry principles, including SAR analysis and: physicochemical property optimization, to compound design and prioritization

  • Ensure experimental data across programs is high quality and well documented,: including procedures, spectra, and failure modes

  • Communicate findings clearly to chemistry, AI research, and life sciences audiences

What they're looking for

  • + years of medicinal chemistry experience beyond the PhD
  • Track record of advancing programs from hit identification through lead optimization
  • Experience directing synthetic chemistry activities at contract research organizations
  • Computational chemistry, cheminformatics, or coding skills, for example: Python with RDKit or pandas for data analysis and automation
  • Experience using AI or ML tools in the life sciences
  • Publications and/or patents demonstrating scientific impact
