About the Job

Requirements

  • A PhD in Chemistry, Medicinal Chemistry, or a related field is required.
  • At least 5 years of industry experience in small-molecule drug discovery is required.
  • A strong foundation in medicinal chemistry and its application to disease-focused drug discovery is required.
  • Experience designing, synthesizing, and optimizing induced proximity medicines, including PROTACs or related approaches, is required.
  • Experience across hit finding, hit-to-lead, and lead optimization, including developing follow-up strategy for high-throughput screening, DNA-encoded, or phenotypic screening, is required.
  • Demonstrated success optimizing compounds for oral exposure and interpreting pharmacokinetic data across multiple species is required.
  • A deep understanding of physicochemical properties and in vitro drug metabolism and pharmacokinetic parameters, including solubility, permeability, metabolic stability, and plasma protein binding, and applying them to lead optimization is required.
  • Experience managing external chemistry contract research organizations and driving synthetic programs efficiently is required.
  • Strong written and verbal communication skills are required.

Responsibilities

  • Design and advance medicinal chemistry strategies for next-generation induced proximity medicines, including bifunctional and molecular glue-related modalities.
  • Lead compound design and structure-activity relationship campaigns from hit finding and high-throughput screening follow-ups through hit-to-lead and lead optimization.
  • Manage external chemistry contract research organizations, including compound design prioritization, synthetic execution, timelines, and data review.
  • Direct external drug metabolism and pharmacokinetic studies and interpret in vitro and in vivo data to guide compound progression.
  • Partner with Biology and Platform teams to design screening strategies and support compound evaluation in biochemical, biophysical, and cellular assays.
  • Contribute to mechanistic studies that strengthen understanding of lead molecules and inform program direction.
  • Support intellectual property strategy through invention generation and contributions to patent filings.
  • Help evaluate and expand opportunities into new disease areas and therapeutic applications.

Desired Qualifications

  • Experience contributing to programs that advanced from discovery into clinical development.
  • A background in computational chemistry, molecular modeling, or molecular dynamics.
  • Familiarity with chemical biology or structural biology techniques, including assay development, compound profiling, pulldown experiments, protein purification, or crystallography.
  • Experience with high-throughput screening or phenotypic screening.
  • Experience in proteomics, including post-translational modification analysis or chemoproteomic target deconvolution.
