• Maintain detailed reagent records including certificates of analysis, qualification data, expiration tracking, and chain-of-custody documentation in compliance with internal SOPs
• Collaborate with internal stakeholders and external vendors to source, evaluate, and qualify new critical reagents, including reference standards, antibodies, and biological materials
• Proactively monitor reagent inventory levels and lead mitigation strategies to prevent supply gaps that could impact testing timelines or project deliverables
• Identify risks associated with critical reagent availability or performance and propose contingency plans to minimize impact on analytical programs
• Maintain and manage cell lines used in cell-based bioassays, including routine passaging, cryopreservation, thawing, and mycoplasma testing in accordance with established SOPs
• Monitor cell health, growth kinetics, morphology, and passage number, maintaining detailed cell culture logs and ensuring cells are within validated passage ranges for assay use
• Establish and maintain working and master cell banks, ensuring proper storage, documentation, and qualification of banked cell stocks
• Perform routine cell-based assay quality controls to confirm cellular performance metrics are within acceptable parameters prior to use in analytical testing
• Troubleshoot cell culture-related issues, including contamination events, performance drift, and growth anomalies, implementing corrective actions and preventive measures as appropriate
• Evaluate and qualify new cell lines or cell-based platforms to support assay development and continuous improvement initiatives
• Contribute to continuous improvement initiatives within the analytical development function, identifying opportunities to enhance assay performance, laboratory efficiency, or data quality
• Evaluate and implement new technologies, methodologies, or platforms to improve analytical capabilities and support pipeline needs
• Participate in the development and optimization of emerging bioanalytical tools and approaches to support next-generation drug development strategies
• Act as a technical point of contact within own work group or project team, providing scientific guidance and fostering a culture of rigor and quality
• Serve as a functional mentor to more junior scientists and research associates, sharing technical knowledge, best practices, and professional development guidance
• Represent the Analytical Development department or function on cross-functional program or project teams and sub-teams, communicating scientific progress, risks, and recommendations effectively
• Collaborate with internal partners across Pharmaceutical Development, Bioanalysis, Quality, Regulatory Affairs, and Manufacturing to align on analytical strategies and deliverables
