Job Details
Legend Biotech is a global biotechnology company dedicated to treating and, one day, curing life-threatening diseases. Headquartered in Bridgewater, New Jersey, we are advancing the next generation of cell therapy through a portfolio of innovative technologies, including autologous, allogeneic, and in vivo cell therapy approaches. Our research spans chimeric antigen receptor T-cell (CAR-T), T-cell receptor (TCR-T), natural killer (NK) cell-based therapies, and other emerging platforms designed to transform the treatment of serious diseases. From our global network of research and development sites, we are committed to discovering and developing safe, effective, and cutting-edge therapies for patients worldwide.
Legend Biotech entered into a global collaboration agreement with Johnson & Johnson to jointly develop and commercialize CARVYKTI® (ciltacabtagene autoleucel; cilta-cel). Through this strategic partnership, we combine complementary expertise and capabilities to advance innovative immunotherapies for patients living with multiple myeloma.
Legend Biotech is seeking a Scientist, Molecular Assays as part of the Bioanalytical Sciences team based in Somerset, NJ.
Role Overview
We are seeking a highly motivated scientist to join our Bioanalytical Sciences team. This position will support the development, execution, and optimization of molecular assays for clinical, translational, and preclinical programs. The successful candidate will contribute to a broad range of molecular biology activities, with primary responsibilities focused on quantitative PCR (qPCR), digital droplet PCR (ddPCR), and next-generation sequencing (NGS), including single-cell sequencing workflows.
The ideal candidate will have hands-on experience with molecular biology techniques, strong laboratory execution skills, and exceptional attention to detail. Experience with qPCR, ddPCR, nucleic acid extraction, NGS library preparation, and biological sample processing is highly desirable. This role offers an excellent opportunity for an early-career scientist to work in a fast-paced biotechnology environment supporting innovative cell and gene therapy programs while collaborating with multidisciplinary teams across research and development.
Key Responsibilities
Perform molecular biology experiments supporting clinical, translational, and preclinical research programs.
Execute qPCR and ddPCR assays for gene expression analysis, biomarker quantification, transgene detection, vector copy number determination, and biodistribution studies.
Support development, optimization, qualification, transfer, and troubleshooting of molecular assays.
Perform nucleic acid extraction, quantification, and quality assessment from blood, tissue, cell culture, and other biological samples.
Prepare samples and perform library preparation for next-generation sequencing (NGS) applications, including single-cell RNA sequencing (scRNA-seq).
Operate and maintain molecular biology instrumentation, including qPCR, ddPCR, and NGS-related platforms.
Analyze experimental data, ensure data quality, maintain accurate laboratory documentation, and assist in the preparation of protocols, SOPs, technical reports, and assay-related documents.
Process, track, and manage biological samples using LIMS and ELN systems while ensuring sample integrity and traceability.
Support laboratory operations, including inventory management, sample shipments, equipment maintenance, and laboratory organization.
Contribute to the continuous improvement of laboratory workflows, assay performance, and operational efficiency.
Requirements
M.S. in Life Sciences, Molecular Biology, Biochemistry, or a related field with 8+ years of relevant experience, or Ph.D. in a related scientific discipline with 3+ years of relevant experience.
Hands-on experience with molecular biology techniques, including nucleic acid extraction, qPCR, RT-qPCR, and/or ddPCR.
Experience with NGS workflows and library preparation; single-cell sequencing experience is a plus.
Familiarity with assay development, data analysis, and biological sample processing.
Experience in cell and gene therapy, immunology, oncology, or regulated laboratory environments is desirable.
Strong attention to detail, organization, and documentation skills.
Excellent analytical, problem-solving, and communication skills.
Ability to work independently and collaboratively in a fast-paced laboratory environment.
Commitment to data quality, laboratory safety, and continuous learning.
Work in a clinical, research, pharmaceutical, or diagnostic laboratory.
May require standing for extended periods and lifting up to 25 pounds.
Use of personal protective equipment (PPE) is required.
Involve handling biological specimens and hazardous materials following safety guidelines.

Company
Legend Biotech was founded as an early-stage cell therapy company in 2014. The company was the brainchild of visionary scientists who recognized that antibody-based therapeutics could potentially treat disease and possessed the backgrounds in immunology and gene editing to take the leap.
For two years, Legend Biotech, then known as the “Legend Project,” operated in a room the size of a freight elevator, with the goal of creating a cell therapy for multiple myeloma, a hematological cancer that often relapses and can become refractory. The team produced nanobodies for single-domain antibody drugs and ultimately extended the half-life of the nanobodies with proprietary technologies.
In 2015, Legend’s scientists focused on research for chimeric antigen-receptor T-cells (CAR-T) targeting the BCMA protein, making the biotech one of the first companies in the world to engineer CAR-T cells for the BCMA protein. In 2016, investigator-initiated trials began in China.
In 2017, data from the trials were presented at the American Society for Clinical Oncology (ASCO), which led to a partnership with biopharmaceutical company Janssen Biotech, Inc. to co-develop the anti-BCMA CAR-T, ciltacabtagene autoleucel (cilta-cel). Applications seeking approval of cilta-cel for the treatment of patients with RRMM are currently under regulatory review by several health authorities around the world. CARVYKTI™ (ciltacabtagene autoleucel) was approved by the U.S. Food and Drug Administration in February 2022 and received conditional marketing approval from the European Medicines Agency in May 2022.
Today Legend Biotech is a global, commercial-stage company driven by a passion for patients. We continue to build our pipeline of cell therapy platforms, which includes CAR-T, CAR-NK, CAR-γδ T and non-gene-editing CAR technologies.
Our goal is to bring hope and opportunity to patients and their families by continuing to explore unique technologies.
