Nitrosamine / Genotoxic Impurities Analyst

Perform and develop trace-level analysis of nitrosamine and genotoxic/mutagenic impurities by LC-MS/MS and GC-MS/HRMS in line with ICH M7 and current nitrosamine guidance, ensuring sensitive, data-integral results supporting risk assessment and control. Key responsibilities: perform trace-level nitrosamine analysis (NDMA, NDEA, NMBA, NDIPA, NEIPA, NMPA, etc.) by LC-MS/MS and GC-MS/HRMS; analyse genotoxic/mutagenic impurities per ICH M7 (assessment, control, AI/PDE/TTC); develop, optimise and validate ultra-trace methods (low ppb/ppm) including sensitivity, recovery and matrix effects; support nitrosamine risk assessments and root-cause with QA/Regulatory/Method Development; operate, tune and maintain LC-MS/MS and GC-MS/HRMS and verify system suitability; manage reference and isotope-labelled internal standards with safety controls; record raw data, chromatograms and calculations contemporaneously (ALCOA++); report and investigate OOS/OOT and perform confirmatory testing; maintain controlled handling/safety of mutagenic substances and waste; and support internal, NABL, FDA and client audits.
