Operate, troubleshoot, and maintain analytical instrumentation, including GC/MS, HPLC, GPC, FTIR, Raman, UV‑vis, and other instruments. Author and maintain analytical documentation, including test methods, validation protocols, SOPs, and technical summaries. Interpret chromatographic, spectroscopic and other relevant analytical and performance testing data to generate clear, actionable technical reports. Lead QA/QC activities related to production batch release to ensure compliance with product specifications. Coordinate method transfers to external contract manufacturers and laboratories, including preparation of transfer protocols, technical documentation, and troubleshooting support during implementation. Provide analytical support for product claims substantiation, designing and executing data‑driven experiments that demonstrate product performance and efficacy. Support the Research team in establishing appropriate experiments to establish POC (Proof‑of‑Concept) and POP (Proof‑of‑Performance) for new technologies. Contribute to a culture of scientific innovation by exploring and implementing emerging analytical methodologies. Identify and apply analytical techniques to characterize product attributes and establish scientific modes‑of‑action for new technologies. Present analytical findings and program updates to internal stakeholders and cross‑functional teams, as well as external partners. Requirements Skills and Experience Significant hands‑on experience with HPLC and GC/MS, including method development, validation, quantitative analysis, and instrument maintenance.
