Laboratory Technician LC-MS / GC-MS

The Laboratory Technician – LC-MS / GC-MS (Genotoxic Impurity Routine Analysis) is responsible for performing routine analytical testing in support of release and stability studies within a GMP-regulated environment. The role focuses on the execution of LC-MS and GC-MS analyses for genotoxic impurity testing, including sample and solution preparation, instrument operation, data review, documentation, and routine instrument care.

The position plays a key role in ensuring timely, accurate, and compliant delivery of analytical results while maintaining high standards of data integrity, laboratory organization, and regulatory compliance. The Laboratory Technician works closely with scientists, reviewers, and laboratory colleagues to support smooth daily operations, instrument reliability, and continuous improvement of routine analytical workflows.

• Perform routine analytical testing for release and stability studies using LC-MS and/or GC-MS methods for genotoxic impurity analysis
• Prepare samples, standards, reagents, and mobile phases in accordance with approved methods and laboratory procedures
• Operate, monitor, and troubleshoot LC-MS and GC-MS systems to ensure smooth and efficient analytical execution
• Ensure accurate, complete, and timely documentation of all analytical activities in LIMS, Chromeleon, and paper-based records, in compliance with GMP and data integrity requirements
• Collaborate closely with scientists, reviewers, and laboratory team members to support daily laboratory operations and project timelines
• Archive raw data and analytical documentation in accordance with internal procedures and regulatory requirements
• Contribute to maintaining a clean, organized, and inspection-ready laboratory environment
