• Act as the subject matter expert for ADCs and large molecule LC-MS/MS analytical assays and associated sample preparation workflows.
• Serve as principal investigator or contributing scientist for LC-MS/MS studies, ensuring scientific integrity and regulatory compliance.
• Ensure all work operates in full compliance with GLP requirements, study protocols, and standard operating procedures (SOPs).
• Maintain open, direct communication with clients, including attending recurring calls and providing scientific updates as needed.
• Prepare all necessary study and laboratory documentation required to support in-lab analysis.
• Complete and deliver high-quality scientific reports to clients on time, clearly summarizing methods, results, and conclusions.
• Prepare biological materials, including animal blood and tissues, for analytical assays to be run on LC-MS/MS instrumentation.
• Maintain and document chain of custody for specimens, reagents, controls, and samples in the laboratory to ensure data integrity.
• Perform analytical assays according to protocol or other guiding documents, ensuring accurate, complete, and contemporaneous documentation.
• Maintain and update facility records related to laboratory operations and analytical activities.
• Review laboratory records, procedures, and study data for completeness, accuracy, and compliance with GLP and internal standards.
• Assist with calibration, optimization, maintenance, and data collection for analytical instruments, including LC-MS/MS systems.
• Perform routine laboratory maintenance, such as cleaning, stocking supplies, and completing equipment maintenance tasks.
• Document deviations from laboratory procedures and study protocols in a timely manner and contribute to the development and implementation of corrective actions.
• Collaborate with internal regulatory and quality departments to ensure robust quality and compliance oversight of GLP SOPs.
• Ensure compliance with GLP, FDA ICH M10 guidelines, ALCOA+ principles, USDA, and AAALAC guidelines, and identify opportunities for process and quality improvement.
• Support multiple concurrent projects by effectively prioritizing tasks and meeting established deadlines.
• Contribute to a collaborative, values-driven culture focused on employee development, customer focus, quality and excellence, respect, and integrity.
