This role offers exposure to a broad and innovative portfolio with meaningful opportunities to shape program strategy, influence molecule quality, and collaborate across a world-class cross-functional organization.

Key Responsibilities

• Design and synthesize macrocyclic small molecules and macrocyclic peptides in support of drug discovery programs across multiple therapeutic areas

• Apply structure-activity relationship (SAR) knowledge to drive iterative DMTA cycles, balancing potency, selectivity, and drug-like properties

• Leverage ADME/DMPK principles to optimize oral bioavailability, metabolic stability, permeability, and pharmacokinetic profiles of macrocyclic and peptidic modalities

• Serve as a recognized subject matter expert whose compound design and SAR insights resolve critical scientific challenges and advance programs through key milestones

• Collaborate closely with Biology, DMPK, Computational Chemistry, and other cross-functional partners to develop and execute efficient molecule design strategies

• Contribute to program strategy discussions, including target product profile (TPP) development and go/no-go decision frameworks

• Proactively identify capability gaps in tools, methods, or synthetic approaches, and champion new strategies - including AI/ML-enabled design - that improve cycle times and design quality across the portfolio

• Effectively communicate scientific findings to internal stakeholders at all levels, including program teams, portfolio boards, and leadership

• Maintain thorough and timely documentation in electronic laboratory notebooks (ELN) in accordance with IP and regulatory requirements

• Lead or contribute to continuous improvement initiatives and coaching efforts that strengthen the broader team's scientific rigor and impact

Basic Qualifications

• Ph.D. in Medicinal Chemistry, Organic Chemistry, Peptide Chemistry, Chemical Biology, or a related field with a minimum of 8+ years of drug discovery experience in the pharmaceutical or biotechnology industry; or BS/MS with 15+ years equivalent experience

Preferred Qualifications

• Demonstrated hands-on experience in the design and synthesis of macrocyclic peptides or macrocyclic small molecules

• Strong foundation in ADME/DMPK principles and their application to drug design, including oral bioavailability, metabolic stability, and PK/PD relationships

• Track record of productive multi-disciplinary collaboration in a pharmaceutical or biotechnology research environment

• Experience across multiple therapeutic areas or modalities, including both macrocyclic peptides and small molecules

• Experience with challenging or undrugged targets requiring non-traditional modality approaches

• Track record of advancing programs to candidate selection

• Track record of publications, patents, or scientific contributions

• Excellent written and oral communication skills; ability to present complex scientific data clearly to diverse audiences
