• Perform routine and non-routine Quality Control testing to support cell therapy manufacturing, including in-process, release, characterization, stability, raw material, and investigational testing in accordance with approved methods, SOPs, specifications, and regulatory requirements.
• Execute and support cell therapy analytical methods, including flow cytometry-based identity, phenotype, purity, and characterization assays; ddPCR/qPCR-based molecular assays; ELISA or multiplex immunoassays; automated cell count and viability assays; potency or functional cell-based assays; osmolality; pH/conductivity; and applicable compendial or platform methods.
• Support testing for product-specific and platform critical quality attributes, including viable cell concentration, total cell dose, percent viability, identity marker expression, target cell population purity, residual or impurity-related attributes, potency, and applicable vector- or transgene-related readouts.
• Support method transfer, verification, qualification, and validation activities, including protocol execution, data analysis, discrepancy resolution, acceptance criteria assessment, and report generation.
• Analyze, trend, and interpret assay performance data to evaluate method reliability, sample results, system suitability, control performance, assay validity, and laboratory performance indicators.
• Perform investigations related to analytical deviations, assay failures, invalid runs, out-of-specification or out-of-trend results, and atypical assay trends; support root cause analysis, product impact assessment, corrective and preventive action development, and change control activities.
• Collaborate with Quality Assurance, Manufacturing, Process Development, Analytical Development, Regulatory Affairs, and client-facing teams to support product testing, method lifecycle management, technology transfer, manufacturing readiness, and technical issue resolution.
• Support analytical control strategies for cell therapy raw materials, in-process materials, drug substance/intermediate materials, drug product, and final product release testing.
• Review and document test results in compliance with SOPs, approved specifications, regulatory expectations, ALCOA+ data integrity principles, and good documentation practices.
• Support internal and external audits by providing analytical testing data, method documentation, investigation records, qualification/validation evidence, and laboratory compliance documentation.
• Maintain laboratory readiness through reagent management, reference/control material handling, logbook completion, inventory control, equipment cleaning, and other assigned laboratory duties.

• Bachelor's degree in Biochemistry, Analytical Chemistry, Molecular Biology, Microbiology or related field with 4+ years of relevant experience (Master's degree preferred), or 10+ years of relevant experience in lieu of degree.
• Hands-on experience with cell therapy analytical methods, including flow cytometry, ddPCR/qPCR, automated cell count and viability, ELISA or multiplex immunoassays, potency or functional cell-based assays, molecular assays, cell culture, and applicable compendial or platform testing.
• Experience with analytical method transfer, verification, qualification, validation, troubleshooting, lifecycle management, and Good Manufacturing Practice implementation in a regulated environment.
• Familiarity with cell therapy Good Manufacturing Practice manufacturing support, aseptic sample handling, chain of custody/chain…
