Lilly recently announced a $4.5 billion investment to create the Lilly Medicine Foundry — the first-ever facility to combine research and manufacturing in a single location, expanding capacity for clinical trial medicines while reducing costs and environmental impact.

Analytical GMP Laboratories (AGL) supports GMP testing across the Lilly Medicine Foundry (LMF) and the broader Product Research & Development (PRD) network, spanning environmental monitoring, microbiology, GMP testing, raw materials, and cleaning/investigations. AGL sits at the intersection of science and quality — this role offers the opportunity to shape the analytical compliance program from the ground up and help drive quality culture at a cutting-edge facility.

The Scientist, GMP Microbiology supports the qualification and routine monitoring of critical utility systems (WFI, PW, clean steam, compressed air, and process gases) at the Lilly Medicine Foundry, ensuring they consistently meet microbiological, chemical, and particulate requirements. The role partners with Utilities, PT&E, Manufacturing, and Quality, serves as an escalation point for utility excursions, and supports root cause investigations in line with cGMP and ALCOA+.
