Contract Scientist/Sr. Scientist - Analytical Development (Cell Therapy)

Responsibilities Lead the development, optimization, and qualification of cell-based potency assays that evaluate the biological activity of cell therapy products. Design and execute functional assays to support product characterization, comparability assessments, stability studies, and manufacturing process changes. Develop and transfer analytical methods used to characterize and monitor Master and Working Cell Banks while ensuring methods are suitable for GMP environments. Analyze complex experimental data, identify assay trends, and apply statistical approaches to evaluate assay performance, reproducibility, and long-term reliability. Generate and review technical documentation including SOPs, protocols, validation reports, method transfer packages, specifications, and regulatory support documents. Collaborate with cross‑functional teams across Process Development, Manufacturing, Quality, and Regulatory to advance analytical strategies throughout product development. Present scientific findings and provide technical recommendations to internal stakeholders and external partners. Mentor junior scientists and contribute to the continuous improvement of analytical technologies and laboratory practices. Requirements PhD in Immunology, Cell Biology, Molecular Biology, Biomedical Engineering, or a related discipline with 2+ years of industry experience, or an MS/BS with 6–10+ years of relevant biopharmaceutical experience. Strong background developing and qualifying cell-based potency assays for cell therapy, biologics, immunotherapy, or related advanced therapeutic products. Hands‑on experience with functional assays such as cytokine secretion, immune cell activation, cytotoxicity, proliferation, or other mechanism‑of‑action assays. Demonstrated ability to independently design experiments, interpret complex data, troubleshoot assay performance, and drive analytical strategy. #J-18808-Ljbffr Commonwealth Sciences, Inc.
