Organization Overview

The Lilly Small Molecule Discovery (LSMD) group is an organization purpose-built to create molecules that make life better for people. We focus on using innovative science to unlock novel approaches that can treat people suffering from diseases with poor treatment options. We continually challenge ourselves to deliver molecules that can provide breakthrough efficacy with the highest possible safety margins. We are dedicated to optimizing our mindset, technology, and processes for faster, more nimble execution. Our success is built on a culture that empowers innovative problem solving through open collaboration and individual accountability.

Advanced Molecule Design (AMD) is dedicated to optimizing molecules into strong drug candidates that become breakthrough medicines for patients. AMD brings together core functional areas — medicinal chemistry, synthetic chemistry, analytical chemistry, computational chemistry, and molecular pharmacology — to accelerate the identification and advancement of high-quality small molecule candidates across a breadth of modalities and therapeutic areas.

Discovery Chemistry Technologies (DCT), a key function within AMD, provides critical scientific expertise and technology solutions that support molecule optimization and discovery chemistry programs. The Chemical Reactivity Landscape sits alongside DCT's Synthetic Innovation Team (SIT), which identifies, integrates, and deploys cutting-edge synthetic chemistry technologies. Where SIT brings modern synthetic methods to the bench, this project builds the predictive layer that tells the organization which conditions to run and why — and the two are designed to operate as one loop. Team members are expected to embrace collaboration, adopt a forward-thinking and growth-oriented mindset, and take individual responsibility for their scientific contributions and professional development.

Position Summary

We are looking for a scientific leader to own the Chemical Reactivity Landscape initiative: a purpose built initiative to build a predictive map of reaction outcomes and generate differentiated reactivity data.

This is a hands-on scientific leadership role working at the intersection of quantum chemistry, machine learning, high-throughput experimentation, and laboratory automation. You will set the modeling strategy across mechanistic, quantum chemical, statistical, and learned approaches; direct the synthetic organic core that gives those models something real to learn; and drive the closed loop in which predictions select experiments and experimental results improve predictions. You will also decide how foundation models and agentic systems are used in reaction discovery.

The project is run in close partnership with the Synthetic Innovation Team (SIT) in Lilly Small Molecule Discovery (LSMD). SIT identifies, defines, and solves the synthetic bottlenecks that matter to the portfolio and brings new methodologies to the bench.

The role is on-site in South San Francisco with both people and project leadership scope.

Key Responsibilities

Scientific Direction & Project Leadership

• Own the scientific vision for the Chemical Reactivity Landscape: working with the Synthetic Innovation Team (SIT) in LSMD, define what the landscape must predict, to what accuracy, for which chemistry, and in what sequence it is built

• Translate scientific ambition into a sequenced plan with dated milestones and decision points, and communicate progress, trade-offs, and risk to senior R&D leadership

• Secure and allocate compute, HTE capacity, and headcount against the highest-value scientific questions

Reactivity Science & Modeling

• Partner with computational chemistry, jointly defining the level of theory, conformational sampling, transition-state treatment, and solvation strategy suited to the scientific question at hand

• Drive descriptor and representation strategy so that models generalize across chemotypes and reaction classes, and so that their predictions can be explained in chemical terms

• Lead catalysis-and other reaction discovery and optimization efforts defining the substrate and condition spaces worth searching

• Maintain deep command of the primary literature across organic chemistry, machine learning, and computational chemistry, quickly judging which advances are worth bringing inside

Autonomous Experimentation & Closed-Loop Discovery

• Set the direction for integrating foundation models and agentic systems into reaction discovery, agents that plan calculations, propose conditions, dispatch experiments to automated and cloud laboratories, and interpret the readouts that come back

• Drive the closed loop between prediction and experiment so that HTE campaigns are selected by the model and their results measurably improve it

• Champion low-friction and conversational interfaces that put reactivity models in the hands of bench chemists without requiring them to become modelers

• Partner with automation, HTE, and analytical leadership so that experiments produce structured, model-ready, traceable data by default rather than by retrofit

Evaluation, Rigor & Scientific Standards

• Establish how models and agents are evaluated before they influence experiments: benchmarks, held-out data, fair expert and random baselines, calibrated uncertainty, and documented failure modes

• Treat scientific evaluation of foundation models as a first-class discipline rather than a post-hoc check, and build the harnesses and reference datasets that make it routine

• Establish reproducibility, data provenance, and clear reporting of each model’s domain of applicability

Team Leadership & Development

• Lead, manage, and develop a team of computational and data scientists across career stages, including the Reaction Informatics individual contributors on this project: set clear expectations, give direct feedback, and create the conditions for high performance

• Lead the matrixed cross-functional project team through scientific credibility and clarity of direction rather than authority

• Mentor and coach scientists at all levels, and give people genuine scientific territory to own and grow into

• Recruit, hire, and onboard across career stages, and invest in early-career scientists as part of the long-term talent pipeline for reactivity modeling at Lilly

• Actively build inclusive team relationships and ensure all team members have appropriate access to challenging work, development opportunities, and visibility

• Foster digital fluency beyond the immediate team: encourage experimentation with new tools, support training opportunities, remove barriers to adoption, and recognize scientists who use these capabilities to accelerate real chemistry

Collaboration, Influence & External Engagement

• Partner with the Synthetic Innovation Team, medicinal chemistry, process chemistry, analytical sciences, and automation to turn portfolio bottlenecks into well-posed scientific questions

• Engage LSMD project teams directly to understand their synthetic bottlenecks, and bring an enterprise mindset — proactively connecting teams to reactivity predictions, AI/ML-assisted retrosynthesis, and emerging technologies beyond the immediate scope of any one program.

• Represent the project in internal governance bodies, scientific forums, and cross-functional decision-making

• Build and manage external collaborations with academic groups, consortia, and technology partners, and evaluate them for strategic fit rather than novelty

• Publish and present in leading chemistry, cheminformatics, and machine learning venues, and use that visibility to attract talent and partners

Safety, Quality & Compliance

• Keep safety as the top priority; provide guidance on HSE related to new technology deployment, and laboratory operations

• Ensure the team maintains rigorous documentation, data integrity, and compliance standards across all computational and experimental work

What Success Looks Like

• The reactivity landscape is the default reference for condition selection across LSMD, and its uncertainty estimates hold up under real use

• Optimization campaigns reach target conditions in measurably fewer experiments than expert-designed baselines, across multiple reaction classes

• Models generalize to out of domain chemistry, and know precisely where they stop working

• Autonomous and semi-autonomous campaigns run reliably against real instruments, with the loop closing without manual intervention

• Evaluation standards set by this project are adopted by other AI-for-science efforts across Lilly

Basic Qualifications

• Ph.D. in Chemistry or a closely related STEM field with 4+ years of relevant experience; or M.S./B.S. with 8+ years of relevant experience

• Deep expertise in synthetic and HTE chemistry applied to organic reactivity — mechanism, and physical organic principles — with a track record of results that changed experimental decisions

Additional Skills / Preferences

• Demonstrated expertise applying machine learning to chemical data, including reaction outcome, reaction condition, or molecular property prediction

• Demonstrated experience leading, managing, and developing scientists across multiple career stages

• Track record of owning a scientific capability or platform end to end: setting direction, deploying it to real users, and iterating based on adoption and impact

• Strong record of scientific contribution including peer-reviewed publications, presentations, and/or patents

• Experience integrating foundation models or agentic systems into scientific workflows, including autonomous or semi-autonomous experimentation

• Experience with automated and cloud laboratories, HTE platforms, and closed-loop optimization at scale

• Depth in catalysis — metal-mediated, organocatalytic, or photoredox — and in catalyst and ligand design

• Experience establishing evaluation and benchmarking methodology for models or agents, including safety review and failure-mode analysis

• Experience with Bayesian optimization, active learning, or LLM-guided optimization for reaction conditions

• Experience building and leading a scientific function or group from an early stage

• Experience managing academic collaborations, consortia, or external technology partnerships

• Experience contributing to scientific standards, governance, or advisory bodies for AI in science

• Familiarity with medicinal chemistry principles and an understanding of scale-up considerations.

• Proficiency with scientific and informatics tools such as ChemDraw, SciFinder, Reaxys, electronic lab notebooks, and data visualization platforms.

• Examples of championing new technology adoption within a team or organization.

• Strong work ethic with proactive, independent initiative; anticipates challenges and proposes solutions.

• Highly organized with strong time management skills; adapts to changing business needs and timelines to deliver timely results.

• Builds positive, respectful working relationships across teams, and engages in constructive dialogue even when navigating differing viewpoints.

• Communicates clearly, thoughtfully, and professionally, adapting style to diverse audiences; actively listens and seeks to understand before responding.

• Views personal success in the context of team success.

• Proven ability to work effectively in a multidisciplinary, multi-site, international team environment
