Job summary

Lilly’s Early Molecule Discovery team seeks a hands-on medicinal chemistry leader with direct experience advancing molecular glue programs from hit finding through candidateselection. The role requires collaboration across pharmacology, structural biology, computational chemistry, and DMPK to translate hypotheses into optimized molecules.

Success depends on deep bench chemistry expertise and strong cross-functional leadership to guide internal and external teams and deliver against timelines.

Qualifications

• PhD in Organic Chemistry or related field with 8+ years of small molecule drug discovery experience; MS with 10+ years; or BS with 12+ years.
• Extensive experience in medicinal chemistry, SAR analysis, and structure- and mechanism-based molecular design.
• Direct experience designing or optimizing molecular glue degraders, including protein–protein interface engagement and E3 ligase biology.
• Demonstrated leadership as a chemistry lead on programs of any mechanism, ideally including a molecular glue program that reached candidateselection.
• Track record of scientific contributions through publications, patents, or external presentations.
• Experience managing or collaborating with external chemistry teams and CROs.
• Experience with novel modalities such as targeted protein degradation and covalent chemistry, and biophysical techniques to understand molecular glue SAR.

Responsibilities

• Lead hit-to-lead optimization of screening hits, improving potency, selectivity, physicochemical properties, and ADMET.
• Apply structure-based and data-driven design, incorporating ternary complex structural data where relevant.
• Design and synthesize novel molecules to test mechanistic hypotheses, including cooperativity-driven SAR for molecular glue chemotypes.
• Design and implement screening cascades tailored to molecular glue pharmacology.
• Direct internal and external medicinal chemistry resources, including CRO relationships, to align with strategy and timelines.
• Oversee high-throughput synthesis, route scouting, and scale-up for efficient compound delivery.
• Maintain a strong safety culture and efficient lab operations.
