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. The Lilly Genetic Medicine group is at the forefront of oligonucleotide medicinal chemistry research and synthetic chemistry innovation, with the goal of establishing Lilly as a leader in genetic medicine. Our group is engaged in a broad range of scientific efforts spanning the full arc of oligonucleotide drug discovery: from the design and synthesis of siRNA and antisense oligonucleotide (ASO) molecules on active drug discovery projects, to fundamental platform science aimed at making better medicines. This includes investigating novel chemical modifications to enhance the potency, selectivity, and durability of siRNA molecules, as well as pioneering new delivery strategies using a variety of ligands to direct oligonucleotide medicines to specific tissues and cell types. We work in close collaboration with in vitro and in vivo biology, ADME and toxicology scientists to translate chemical innovation into meaningful therapeutic impact.We are seeking a synthetic chemist who is passionate about applying their expertise to this exciting and rapidly evolving field. In this role, you will contribute to both active drug discovery projects and broader platform science efforts, working alongside a multidisciplinary team to advance the design, synthesis, and profiling of oligonucleotide molecules. The successful candidate will independently identify key scientific questions, apply innovative solutions, and contribute meaningfully to data-driven decision-making across the portfolio.ResponsibilitiesDesign and synthesize oligonucleotides and novel nucleotide analogs for incorporation into siRNA and ASO platforms to support portfolio drug discovery effortsIndependently identify critical scientific questions and develop well-reasoned chemistry strategies for enhancing the potency, safety, and durability of oligonucleotide drug moleculesCollaborate with in vitro and in vivo biologists to evaluate new biological targets of interest, integrating cross-functional information to support data-driven decisionsDesign and implement chemistry strategies for delivery of oligonucleotide medicines to tissues and cell types of interest, anticipating and managing risk to minimize impact on project timelinesDevelop and test new ideas and apply innovative solutions that significantly advance scientific and/or project understanding across multiple drug modalities, including oligonucleotides, antibody-oligonucleotide conjugates, and peptide-oligonucleotide conjugatesBuild a diverse cross-functional and external network to understand how different fields contribute to oligonucleotide research and developmentFocus on defining clear scientific hypotheses, goals, critical success factors, and timelines in support of advancing the portfolioMentor and develop junior scientists, providing constructive feedback and encouraging a culture of excellence and knowledge sharingBring authentic scientific perspective and create a safe environment for colleagues to share ideas and contributeRepresent genetic medicine project teams in presentations to departmental and cross-functional senior leadership teamsBasic QualificationsPh.D. in organic chemistry, or a related field with 0–5+ years of experience in the pharmaceutical industry or relevant postdoctoral trainingAdditional Skills/PreferencesStrong proficiency in synthetic organic chemistry, including design and execution of multistep synthetic routes to small molecule targetsExpertise in characterization of small molecules using NMR spectroscopy, mass spectrometry, and HPLCExperience with oligonucleotide synthesis using automated synthesizers (e.g., Mermade or K&A platforms) and downstream oligonucleotide processing is desirable but not requiredExperience with conjugation of biomolecules is desirable but not requiredDemonstrated ability to think creatively, try new ideas, and apply findings in a fast-paced discovery environmentFamiliarity with ChemDraw, electronic notebook software, and Microsoft OfficeAdditional InformationTravel: 0–10%Location: On-site, Indianapolis, IN – Lilly Corporate Center (LCC)Lilly is dedicated to helping individuals with disabilities to actively engage in the workforce, ensuring equal opportunities when vying for positions.
