About the Role

We are seeking a Principal/AD Medicinal Chemist to lead and advance small molecule drug discovery programs from early hit identification through IND-enabling studies. This is a senior, hands-on scientific leadership role requiring deep expertise in medicinal chemistry, strategic thinking, and cross-functional collaboration. The candidate will direct work to be completed at a CRO. This position calls for a highly creative and experienced chemist who can independently design and execute medicinal chemistry strategies while contributing to the integration of computational and AI-driven approaches into drug discovery workflows. The ideal candidate will combine strong technical depth with the ability to guide internal teams and external partners toward impactful outcomes.

Responsibilities

  • Propose and independently drive medicinal chemistry strategies to progress programs from hit identification through lead optimization to development candidate selection
  • Lead chemistry efforts within cross-functional project teams, which include bench biologists, DMPK lead, non-clinical tox lead, computational scientists, ML engineers
  • Design, prioritize, and guide synthesis of novel compounds using structure-based and ligand-based approaches to optimize potency, selectivity, pharmacokinetics and developability
  • Interpret and integrate SAR, structural biology, DMPK, pharmacology, and safety data to drive compound design and progression
  • Contribute to and integrate AI-driven and computational modeling insights into compound design strategies
  • Serve as a technical leader and mentor for internal chemists and external collaborators
  • Manage external CRO partnerships to ensure high-quality and timely delivery of chemistry objectives
  • Communicate program strategy, data, risks, and recommendations to senior leadership
  • Author and contribute to patent strategies and applications, scientific publications, and internal reports

Requirements

  • Applicants must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time.
  • PhD in Organic Chemistry or a related field with 3-8 years of industry experience in medicinal chemistry
  • Proven track record of advancing drug discovery programs through key milestones (Hit-to-Lead and Lead Optimization)
  • Deep expertise in synthetic organic chemistry, including modern methods and reaction mechanisms
  • Strong experience in structure-based and ligand-based drug design
  • Demonstrated ability to optimize compounds for potency, selectivity, and DMPK/safety properties
  • High level of creativity, productivity, and independent problem-solving ability
  • Experience managing external CROs and collaborating across disciplines
  • Excellent communication skills with the ability to clearly present complex scientific concepts
