Scientific Director, Process Chemistry - Oligonucleotides

Organization and Position Summary

Our SMDD team is looking for experienced and creative candidates with experience in chemistry, manufacturing, and controls (CMC) of oligonucleotides to participate in the development of chemistry in support of scalable and environmentally friendly manufacturing processes. This technical role will support emerging synthetic needs across the rapidly evolving Lilly Genetic Medicines (LGM) portfolio. The scientist will collaborate with a growing team comprising chemists, analysts, and engineers focused on the development and optimization of existing methods and exploration of novel synthetic approaches to oligonucleotides and their conjugates.

The position presents an opportunity to lead CMC activities to support clinical trials, product commercialization, and regulatory submissions of oligonucleotide therapeutics. Developing and working with both internal manufacturing (Lilly Medicine Foundry) and external contract manufacturing organizations (CMOs) to support oligonucleotide synthesis, tech transfer, and campaign execution will be important aspects of this role.

• Bring extensive oligonucleotide CMC expertise to SMDD and grow internal capability through coaching, mentorship, and technical leadership across a diverse portfolio — complex single strands, siRNA, and oligonucleotide conjugates (AOC and PRC).
• Apply modern synthetic organic and nucleic acid chemistry to challenge existing methods, define new manufacturing technologies, and address key CMC challenges across the LGM portfolio.
• Develop and apply impurity control strategies aligned with the current global regulatory climate; address CMC regulatory questions enabling clinical studies and marketing authorization applications. Prior experience in validation activities preferred.
• Provide technical leadership across route design, process development, equipment selection, and scale‑up — from laboratory plans through demonstration on development‑ and commercial‑scale equipment, partnering with internal manufacturing (Lilly Medicine Foundry) and external CMOs to deliver robust processes for clinical and commercial supply.
• Demonstrate strong skills with automated reactor platforms and purification technologies and apply them across the oligonucleotide portfolio.
• Collaborate across internal CMC networks (Drug Product Delivery, Project Management, Quality, Manufacturing, and Regulatory) to deliver materials and documentation for clinical trials and regulatory submissions.
• Identify and integrate external chemistry innovations to complement internal capabilities; represent Lilly externally through presentations at symposia and consortia and publications in peer‑reviewed journals.
• Contribute novel chemical design and mechanism‑based problem solving (e.g., total synthesis, methodology development, oligonucleotide synthesis), reflected in a strong peer‑reviewed publication record.
• Lead through ambiguity and change; encourage initiative, accountability, and diverse perspectives across the team.

• PhD in a relevant scientific discipline with 5+ years of relevant industry experience (synthesis, oligonucleotides, solid‑phase synthesis, CMC); or
• MS in a relevant scientific discipline with 8+ years of relevant industry experience (synthesis, oligonucleotides, solid‑phase synthesis, CMC).
• Experience with in the pharmaceutical sector: active ingredient development and associated formulated products; developing chemical processes from mid‑development (proof of concept) through commercialization.
• Experience in development and CMC including quality and regulatory interactions.
• Experience with tech transfer of processes into manufacturing operations.

• Strong interpersonal skills and a collaborative working style.
• Demonstrated initiative and appropriate risk‑taking.
• Demonstrated technical proficiency and ability to create ideas for future work plans.
• Strong technical skills that deliver business value.
• Knowledge and experience with management of a technical project.
• Demonstrated leadership capabilities, especially in a team environment.
• Ability to prioritize multiple activities and manage ambiguity.
