Principal Scientist/ Senior Principal Scientist, Large Molecule Biology Full-time

Principal Scientist / Senior Principal Scientist

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. Beyond breakthrough medicines, we support communities through philanthropy and volunteerism. As a member of Oncology – Large Molecule Biology, you will join a team at the forefront of pharmaceutical science, designing and executing studies that advance portfolio programs with minimal supervision. You will apply deep expertise in biological assays, develop and optimize specialized methods, and collaborate cross-functionally to support multiple research programs.

In this role, you will design and execute in vitro and ex vivo studies that advance priority oncology targets through the drug discovery pipeline. Working with minimal supervision, you will contribute to multiple programs, develop new methods, and partner across disciplines to inform decisions on therapeutic candidates.

• Execute in vitro pharmacology assays to evaluate tumor cell signaling, antibody binding and internalization, cytotoxicity, effector function, cytokine release, and other cellular responses for medium- and high-throughput drug screening.
• Develop, validate, and run bioanalytical assays and maintain, culture, and passage multiple cell lines to support experimental objectives.
• Conduct multiparameter flow cytometry and other in vitro and ex vivo assays (e.g., receptor occupancy, receptor density, PK/PD, tumor isolation, and blood cell analysis) to characterize binding interactions and cellular responses.
• Oversee experimental work conducted by third-party collaborators and vendors, and partner with project and senior leaders to advance molecules through development.
• Present findings to technical and non-technical stakeholders through preclinical reports, team meetings, and presentations.

Basic Requirements:

• B.S. in Biology, Chemistry, Pharmacology or a related field with 5+ years of relevant experience, or an M.S. in Biology, Chemistry, Pharmacology or a related field with 3+ years of relevant experience (role level based on relevant experience).
