The Sr. Principal Chemist is a member of AQCO’s Analytical Sciences Team and will have a primary responsibility for conducting non‑routine analyses of drug substances, drug products, and other non‑typical samples suspected to involve counterfeiting, tampering, or diversion using a variety of analytical techniques/instrumentation (e.g., HPLC, UPLC, Spectroscopy, etc.). Samples associated with these investigations may originate from: product complaints, proactive surveillance (by Lilly security and/or legal), or global law enforcement/government agencies. Sample types include but are not limited to small molecules, peptides, therapeutic proteins, sRNAs, gene therapy and drug conjugates. The Sr. Principal Chemist will also contribute to developing advanced authentication strategies/analytical techniques for pipeline assets.

Key Responsibilities Perform analyses of suspect products using LC‑MS (including intact mass and peptide mapping), HPLC, UPLC, spectroscopy and other analytical techniques. Analyze LC‑MS data and perform limited structure elucidation on both small and large molecules. Provide non‑laboratory support for other product authentication processes (e.g., packaging authentication, packaging variable data verification, etc.). Collaborate with AQCO colleagues and other analytical SMEs to solve complex sample analyses. Support special studies proposed by business partners (e.g., Global Security, Legal). Develop and validate robust scientifically advanced methods with the required performance attributes to satisfy stakeholder needs. Actively participate in mass spectrometry community / forums to maintain proficiency and expertise. Troubleshoot issues with methods and/or equipment. Execute testing protocols in accordance with local procedure and regulatory requirements. As required, provide training or mentorship to other AQCO colleagues or cross‑functional team members. Job specific pre‑requisites Deep technical expertise in separation sciences, spectroscopy, hyphenated mass spectrometry techniques (MS and MSn.) and their application.
