Job Description
Discovery Process Chemistry
Lilly Small Molecule Discovery (LSMD) • Louisville, CO
Company Overview
At Lilly, we serve an extraordinary purpose. We make a difference for people around the globe by discovering, developing, and delivering medicines that help them live longer, healthier, more active lives. Not only do we deliver breakthrough medications, but you also can count on us to develop creative solutions to support communities through philanthropy and volunteerism.
Organization Overvi ew
Lilly Small Molecule Discovery is purpose-built to create molecules that make life better for people, using innovative science to unlock novel approaches for diseases with poor treatment options. Within Advanced Molecule Design, the Discovery Process Chemistry team focuses on route scouting, leveraging advanced synthetic technologies, and enabling rapid scale-up to deliver up to hundred-gram quantities of key intermediates and potential drug candidates.
Position Summar y
This is a lab-facing scientific role. The scientist will design and execute multi-step synthetic routes to deliver key drug intermediates and candidates on aggressive discovery timelines, applying process chemistry principles to optimize reactions for yield, purity, safety, and scalability. The role takes advantage of our world-class facilities and scientists in Louisville and throughout the Lilly network, leveraging in-house enabling technologies and, where appropriate, CRO partnerships to accelerate molecule progression toward the clinic, and offers the opportunity to work in a collaborative, growth-oriented team that values individual accountability and collaboration.
Responsibilities
Top candidates for this position will be expected to:
Route design: Design and execute multi-step synthetic routes to deliver key drug intermediates and candidates on aggressive discovery timelines, applying literature precedent creatively to develop differentiated strategies for assigned targets.
Process chemistry: Optimize reactions for yield, purity, safety, and scalability, anticipating future scale-up requirements from early-stage work.
Enabling technologies: Use flow chemistry, photochemistry, electrochemistry, and automated synthesis platforms to accelerate synthesis and improve process robustness and share learnings to help expand these capabilities.
Safety: Conduct thermal risk assessments (DSC, reaction calorimetry) and hazard evaluations as a standard part of safe scale-up; complete risk assessments before experiments and escalate concerns immediately.
Developability: Proactively assess synthetic feasibility, route complexity, reagent availability, and estimated cost of goods at the earliest possible stage, and communicate synthetic risk and developability flags to the project team.
CRO collaboration: Complement hands-on in-house work by providing clear scientific direction to CRO partners, critically reviewing deliverables, giving actionable feedback, and escalating scientific or quality issues to the project lead as appropriate.
Tech transfer and documentation: Prepare high-quality experimental reports, synthetic procedures, and data packages, and support tech transfer by preparing process documentation and participating in knowledge transfer with CMC colleagues.
AI/ML and digital tools: Integrate AI/ML tools, predictive modeling, and data-driven approaches into synthetic planning and reaction optimization, and data visualization solutions to extract insights from experimental data.
Collaboration: Engage openly in cross-functional discussions with tox, ADME, analytical, and CMC colleagues; independently prioritize competing demands; and mentor and develop team members.
Scientific communication: Identify opportunities for internal or external publications, posters, and presentations.
Compliance: Follow all site safety, environmental, documentation, and regulatory requirements. Actively reinforce a safety-first team culture.
Basic Qualification s
Ph.D. in Organic Chemistry, Inorganic Chemistry, Medicinal Chemistry or other closely related discipline (All requirements must be met no later than August 2027); OR M.S with 8+ years of relevant industry experience; OR B.S with 10+ years of relevant industry experience.
Strongly preferred
Synthetic and process chemistry: strong background in synthetic organic chemistry, including route scouting, reaction optimization, process chemistry, and scale-up, with extensive working knowledge of modern methodologies, isolation and purification techniques, and structural characterization.
Enabling technologies: experience with flow chemistry, photochemistry, electrochemistry, or automated synthesis platforms.
Developability: familiarity with early-stage developability concepts, including synthetic feasibility, cost of goods, and regulatory starting material designation.
CRO management: experience managing or coordinating work with CRO partners in a discovery or process chemistry context.
Additional skills and preference s
Demonstrated ability to independently design and execute multi-step synthetic routes in a drug discovery or process chemistry setting.
Proven track record of contributing to peer-reviewed scientific publications.
Effective English-language written and verbal communication skills.
Active engagement with current synthetic chemistry literature, with discernment regarding the limitations and scalability of new transformations.
Proficiency with Microsoft Office, ChemDraw, SciFinder, Reaxys, and other scientific data tools.
Working familiarity with data science tools or AI/ML applications relevant to synthetic chemistry workflows.
Proven ability to mentor junior scientists and contribute to a collaborative, inclusive team culture.
Strong organizational skills with a track record of delivering high-quality results under competing timelines.
Additional Informatio n
Work environment is laboratory-based, with hands-on work with chemical reagents, synthetic equipment, and analytical instrumentation; standard personal protective equipment is required. Occasional support of work across multiple lab spaces or collaboration in office and meeting environments is needed.
Potential exposure to chemicals, allergens, and loud noises.
Travel: 0 to 10%.
