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…
