Legend Biotech is seeking a Scientist, Immunoassays as part of the Bioanalytical team based in Somerset, NJ.

Role Overview

The Scientist, immunogenicity & Immunoassays is responsible for developing, qualifying, validating, and supporting bioanalytical assays used to assess immunogenicity and immune responses in preclinical and clinical studies. The successful candidate will have hands-on experience with Anti-Drug Antibody (ADA) assays, ELISAs, and other ligand-binding immunoassays and will contribute to assay development, method optimization, sample analysis, data interpretation, and regulatory documentation.

This position requires strong laboratory skills, scientific problem-solving abilities, and the capability to work collaboratively in a cross-functional environment supporting cell therapy, and gene therapy programs

Key Responsibilities

• Perform method development, qualification and validation for of soluble biomarker and immunogenicity (ADA) assays using ligand binding assay (ELISA, MSD and Luminex).
• Troubleshoot assay related issues with minimal guidance.
• Prepare and review assay protocols, validation plans, reports, SOP and technical documents.
• Data analysis using relevant analytical software.
• Perform routine laboratory responsibilities such as sample coordination, receiving and reconciliation using LIMS with maintaining adequate chain of custody and documentation.
• Use of ELN (electronic notebooks) to record laboratory work and for inventory management.
• Ensure the documentation and laboratory work is in compliance with GXP and GLP like regulatory environments.
