Mixed Modality (Peptide Downstream) Scientist - Process Translation and Execution

Lilly Medicine Foundry Chemist

At Lilly, the work is demanding because patients are waiting. We unite caring with discovery to help make life better for people around the world, knowing that every decision, every detail, and every day matters. Headquartered in Indianapolis, Indiana, our over 50,000 employees around the globe take on complex challenges to discover and deliver life-changing medicines, strengthen how health is understood and managed, and support the communities we serve.

This is hard, urgent, selfless work—but it's work worth doing. If you're driven by purpose and ready to bring your best to work that truly matters for patients, we invite you to join us.

Lilly recently announced a $4.5 billion investment to create the Lilly Medicine Foundry, a new center for advanced manufacturing and drug development, Lebanon, Indiana. The first-ever facility of its kind, combining research and manufacturing in a single location, the Medicine Foundry will allow Lilly to further develop innovative solutions to optimize manufacturing processes and increase capacity for clinical trial medicines, while also reducing costs and environmental impact.

The Process Translation and Execution (PTE) team translates API/DS process knowledge into clinical supply readiness, oversees technology transfer, implements phase-appropriate control strategies, and ensures right-first-time clinical manufacturing for a variety of modalities, including synthetic molecules, biologics, peptides, oligonucleotide, and bioconjugates (ADC, ARC, etc.). Through cross-functional collaboration, PTE influences process design, revolutionizes clinical manufacturing, builds capabilities in emerging technologies and aligns with corporate and Lilly Research Labs (LRL) goals, drives scientific excellence and innovation to accelerate manufacturing advancements and propels the site toward long-term business success.

In the Foundry Construction and Project Delivery/Startup Phase (2025 to 2028), roles will be fluid and dynamic as we build a new organization, design and implement the necessary systems and business processes required to enable operational readiness, support the project delivery, and build the site culture. Success will require significant collaboration, creativity, and resilience as the Lilly Medicine Foundry transitions from design to startup and ultimately to steady-state operations and continuous improvement.

This period presents a unique opportunity for learning, growth, and making a lasting impact.

We are seeking passionate and agile chemists to join the PTE team and help bring the Lilly Medicine Foundry's vision to life.

In this role, the Mixed Modality (Peptide Downstream) Scientist will be responsible with evaluating and facilitating the transfer of peptide downstream manufacturing processes, under appropriate supervisory guidance, from development laboratories to pilot plant operations (including kilo-scale and isolator production environments). This enables the successful transition to early-phase cGMP manufacturing of grams to kilogram quantities of API required for clinical trial supply.

• Perform peptide purification and isolation and assess purification methods from early phase process research and development labs
• Familiarity with performing peptide downstream procedures, such as reverse-phase chromatography, TFF, lyophilization, and precipitation & drying.
• Evaluate the safety of the incoming procedures in collaboration with the safety group and process engineering.
• Ordering and staging chemicals.
• Obtain reference materials and participate in setting up analytical methods.
• Reprocess and analyze analytical data to make fact-based decisions.
• Efficient with summarizing and presenting chemistry and challenges.
• Perform familiarization executions to ensure plant readiness of process steps including chemical reactions, purification, TFF, lyophilization, and precipitation & drying at the Lilly Medicine Foundry.
• Perform use-tests of key in-process materials and document Definitive Lab Trials of processes to confirm plant readiness.
• Maintain a well-organized and detailed lab notebook with accurate descriptions of the procedures, observations, and organized analytical data to enable the preparation of technical packages/technical transfers and accurate replication in receiving labs.
• Author, review technical documents, including tech transfer plan, standard operating procedures (SOPs), batch records, campaign summary reports, and deviation reports.
• Apply scientific knowledge to identify areas for improvement and implement new technologies or procedures.
• Contribute to process troubleshooting and investigations by supporting process deviations, quality events, and non-conformances. Collaborate with teams to perform root cause analysis (RCA) and develop effective corrective and preventive actions (CAPAs)
