Design and synthesize macrocyclic small molecules and macrocyclic peptides enabling hit-to-lead progression across multiple therapeutic areas.

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

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

Leverage ADME/DMPK principles to optimize oral bioavailability, metabolic stability, permeability, and pharmacokinetic profiles of synthetic macrocycles

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

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

Mentor junior scientists and contribute to a collaborative, scientifically rigorous team culture

Basic Qualifications

Ph.D. in Medicinal Chemistry, Organic Chemistry, Peptide chemistry, Chemical Biology, or a related field

Minimum of 8 years of relevant industry experience in drug discovery

Preferred Qualifications

Demonstrated hands-on experience in macrocycle hit-finding and 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 macrocyclic small molecules

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

Understanding of clinical translation considerations, including candidate nomination criteria and IND-enabling studies

Strong scientific publication or patent record

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