Associate Scientist, Analytical Development

Responsibilities

• Scientific & Technical Execution
• Design and execute the next logical steps in a series of related experiments and studies, applying scientific reasoning to advance analytical development objectives
• Develop, optimize, qualify, and validate ELISA and cell-based assays (e.g., potency assays, binding assays, reporter gene assays) in support of Process Development and CMC.
• Generate, analyze, and interpret complex analytical data sets; prepare clear and accurate scientific documentation including assay reports, protocols, SOPs, and technical summaries
• Troubleshoot routine and non-routine assay problems, applying systematic problem-solving approaches to identify root causes and implement corrective actions
• Ensure all laboratory work is conducted in compliance with GxP regulations, internal SOPs, and applicable regulatory guidelines.
• Routine Testing
• Perform routine analytical testing in support of drug substance and drug product characterization, stability studies, comparability studies, and release testing activities
• Execute qualified and validated ELISA and cell-based assays in accordance with approved protocols and SOPs, ensuring data accuracy, reproducibility, and traceability
• Document all testing activities thoroughly in electronic laboratory notebooks (ELN) or LIMS, maintaining complete and audit-ready records in compliance with GxP standards
• Review and verify analytical data for accuracy and completeness, escalating deviations or out-of-specification results through appropriate channels in a timely manner
• Support method transfers, cross-site validations, and tech transfer activities as needed to ensure continuity of analytical testing operations
• Critical Reagents Management
• Oversee the lifecycle management of critical reagents used in ELISA and cell-based assays, including procurement, qualification, characterization, storage, and inventory tracking
• Conduct bridging and comparability studies for critical reagent lots to ensure consistency in assay performance across transitions and reagent changes
• 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
• Cell Culture Maintenance
• 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, imple
