We are committed to offering a range of benefits and work-life resources designed to support people in the following areas: Physical and Emotional Wellness Financial Wellness Support for Caregivers For a full list of our comprehensive benefits, see our website: https://www.sarepta.com/join-us The Importance of the Role The Scientist II, RNA Process Development will contribute to Sarepta's smallmolecule and oligonucleotiderelated chemistry efforts, supporting development and characterization of intermediates, impurities, and reference standards that enable RNA Drug Substance manufacturing (PMO, PPMO, PMOx, and siRNA). The role will focus on synthetic route design, impurity identification and synthesis, bioconjugation, and bench to pilotscale execution. The ideal candidate brings strong problemsolving skills, handson synthetic chemistry expertise, and the ability to work crossfunctionally in a fastpaced development environment. This role will directly influence synthetic strategy and contribute to the advancement of Sarepta's RNA manufacturing platforms. The Opportunity to Make a Difference Design and execute synthetic routes for novel small molecules, intermediates, degradation products, and impurities related to RNA drug substance manufacturing. Develop scalable, robust synthetic procedures; evaluate reaction scope, optimization, and critical process parameters. Identify, elucidate, and synthesize processrelated impurities and degradants using spectroscopic data (NMR, LCMS, HRMS, IR). Collect, review, and present process data in group settings and apply statistical methodology to evaluate and optimize process operations. Support scaleup efforts from milligram to multigram quantities; contribute to tech transfer to internal pilotscale labs or external CRO/CMO partners. Evaluate reaction safety, solvent selection, impurity formation mechanisms, and scalability risks. Engage in troubleshooting sessions for processes and products manufactured in-house and at CMOs. Perform technical review of executed Batch Production Records from CMOs during Technology Transfer. Serve as a subject matter expert in cross-functional teams, influencing decisions on CMC strategy, regulatory filings, and risk mitigation.
