Chemist – Method Development and Validation Duties:

• Perform method validation, verification, and robustness studies for established HPLC, UPLC, LC‐MS/MS, HS‐GC, GC‐FID, HPTLC, UV‐Vis, and FTIR methods under the direction of senior method development staff.
• Assist with development of lower‐complexity analytical methods for routine testing, following USP <1225>, USP <1226>, and AOAC Appendix K, with technical review by senior chemists.
• Support method transfer activities (e.g., HPLC to UPLC) for routine methods, including preparation of associated documentation and data packages.
• Perform method optimization for already developed methods (such as minor adjustments to gradients, injection volumes, sample preparation steps) to improve robustness and efficiency.
• Train quality control chemists on validated and transferred methods and provide routine technical support, escalating complex issues to senior chemists.
• Execute non‐routine testing of Research and Development (R&D) materials using established methods and summarize results for senior review.
• Analyze samples to determine chemical and/or physical properties, composition, and/or structure utilizing chromatography, spectroscopy, and spectrophotometry according to approved methods.
• Maintain a well‐documented laboratory notebook and ensure all work complies with cGLP and cGMP guidelines.
• Participate in daily laboratory functions, calibration activities, hygiene events, and routine laboratory cleaning and maintenance.
• Assist with writing and editing laboratory documentation such as standard operating procedures, test methods, or training protocols under direction of laboratory management.
• Perform chemical and physical inventory of laboratory supplies, reagents, solvents, and standards on a consistent basis.
• Support instrumentation calibration and maintenance schedules to ensure proper condition and calibration of laboratory instrumentation and equipment.
• File appropriate paperwork when modifications to laboratory procedures or processes are necessary, such as deviations and change control documentation, with input from senior staff.
• Other miscellaneous duties as assigned by laboratory management.
