Job Description:

At Lilly, we unite caring with discovery to make life better for people around the world. We are a global healthcare leader headquartered in Indianapolis, Indiana. Our employees around the world work to discover and bring life-changing medicines to those who need them, improve the understanding and management of disease, and give back to our communities through philanthropy and volunteerism. We give our best effort to our work, and we put people first. We’re looking for people who are determined to make life better for people around the world. Advisor/Senior Advisor, Investigative Toxicology Indianapolis, Indiana, USA Position Overview We are seeking a talented scientist to join the growing Investigative toxicology group. This individual contributor role is primarily focused on the discovery pipeline from hit identification through candidate selection, with primary responsibility for developing and applying advanced in vitro models (co-culture systems, iPS-derived cells, spheroids, organoids, organ-on-a-chip) or new approach methodologies (NAMs) to address mechanistic/investigative toxicology questions across liver, cardiac, gastrointestinal, kidney, or CNS. The ideal candidate brings direct, hands-on experience with advanced vitro systems gained through PhD training and postdoctoral or industry experience and the scientific depth to develop/qualify in vitro models that allow translational data generation. Key Responsibilities: Develop, qualify, and apply advanced human-relevant in vitro systems such as iPS-derived cell models, organoids, spheroids, co-culture platforms, and MPS/organ-on-a-chip systems to assess safety liabilities with a focus on either liver, cardiac, GI, kidney, or CNS. Qualify novel assays and endpoints that improve the sensitivity/specificity, throughput, and translational relevance of early safety screening. Independently troubleshoot, optimize, and innovate experimental approaches; uphold a high standard of scientific rigor and reproducibility. Evaluate emerging NAMs and drive the adoption of platforms that meaningfully strengthen the human relevance of Lilly's early safety screening and mechanistic investigations. Investigate mechanisms of compound-induced toxicity in target organs using functional assays, high-content imaging, and transcriptomic or metabolomic profiling as appropriate. Serve as a scientific point of contact for CRO and academic partners, overseeing study design, data quality, and delivery; ensure external work meets Lilly's standards for rigor and reproducibility. Participate in pre-competitive consortia and industry working groups advancing NAMs and early safety science. Minimum requirements PhD in Toxicology, Pharmacology, Cell Biology, Biomedical Engineering, or a scientific discipline. PhD with 2 years of postdoctoral or industry research experience with hands-on work in advanced in vitro model systems. Senior Advisor: PhD with 5 years of postdoctoral or industry research experience, evidence of scientific contribution and leadership. Experience in vitro model systems, including experience either (1) developing and optimizing complex platforms such as iPS-derived cell models, organoids, 3D co-culture systems, or MPS/organ-on-a-chip systems, or (2) applying these advanced models to investigate mechanisms of toxicity or address organ-specific safety questions across liver, cardiac, GI, kidney, or CNS biology. Additional Skills/Preferences Proven ability to independently design and execute rigorous experiments, manage multiple projects simultaneously, and prioritize effectively. Excellent written and oral communication skills, demonstrated by peer-reviewed publications and/or conference presentations. Ability to work collaboratively in a matrixed team environment. Experience with complementary platforms such as high-content imaging, MEA electrophysiology, or omics-based approaches (transcriptomics, metabolomics) applied in a safety or mechanistic context as applicable. Experience with immune system is a plus. Experience mentoring junior scientists, graduate students, or postdoctoral researchers.
