Major responsibilities
- Develop, optimize, validate, and transfer flow cytometry analytical methods for cell therapy products, including CAR-T cell therapy and other advanced cell therapy modalities.
- Develop and optimize multiparameter flow cytometry assays for cell identity, purity, viability, transduction efficiency, CAR expression, immune phenotyping, activation, differentiation, exhaustion, and other critical quality attributes (CQAs).
- Design antibody panels and optimize staining conditions, compensation, controls, gating strategies, and assay parameters to ensure robust and reliable analytical performance.
- Perform analytical method validation in accordance with applicable regulatory and quality requirements, including specificity, accuracy, precision, linearity, range, detection/quantitation capability, robustness, and stability, as applicable.
- Perform troubleshooting and root-cause analysis for assay variability, unexpected results, and instrument-related issues; implement appropriate corrective and optimization measures.
- Analyze and interpret flow cytometry data using FlowJo or equivalent software, and perform appropriate statistical analysis.
- Prepare and maintain analytical development and validation protocols, reports, SOPs, analytical procedures, method transfer documents, and other technical documentation.
- Support regulatory submissions, technology transfer, process development, QC method implementation, investigations, and audit preparation.
- Operate, maintain, and troubleshoot flow cytometers and associated laboratory equipment in accordance with established procedures.
- Collaborate with R&D, Process Development, QC, QA, and Regulatory teams to support project milestones and resolve analytical or product-related issues.
- Contribute to analytical platform development, continuous improvement, technical training, and the implementation of new flow cytometry technologies.
