Legend Biotech is a global biotechnology company dedicated to treating, and one day curing, life-threatening diseases. Headquartered in Somerset, New Jersey, we are developing advanced cell therapies across a diverse array of technology platforms, including autologous and allogenic chimeric antigen receptor T-cell, T-cell receptor (TCR-T), and natural killer (NK) cell-based immunotherapy. From our three R&D sites around the world, we apply these innovative technologies to pursue the discovery of safe, efficacious and cutting-edge therapeutics for patients worldwide.
Legend Biotech entered into a global collaboration agreement with Janssen, one of the pharmaceutical companies of Johnson & Johnson, to jointly develop and commercialize ciltacabtagene autolecuel (cilta-cel). Our strategic partnership is designed to combine the strengths and expertise of both companies to advance the promise of an immunotherapy in the treatment of multiple myeloma.

- Ability to execute bioprocess development studies in the lab (including bioreactor runs, upstream engineering, and downstream processing), document the procedure, and interpret process development experiment results.
- Ability to execute the bespoke manufacturing process in the GMP suite, and document the procedure on Master Batch Records (MBRs) in a GMP-compliant environment.
- Author technical protocols, technical reports, SOPs, and MBRs for upstream, downstream, and cell therapy manufacturing processes.
- Ability to maintain accurate and updated lab notebooks and manufacturing records.
- Work within the team to manage equipment (such as bioreactors and purification systems) and records for maintenance, calibration, cleaning, and operation, and lead the effort to maintain laboratory inventories.
- Provide technical support and engineering expertise as a Subject Matter Expert (SME) for manufacturing root cause investigations for Deviations and CAPA.
- Ability to use engineering and statistical tools to analyze and organize process development and manufacturing data with scientific integrity, and in a clear and concise manner.
- Ability to work collaboratively with the EDD, Analytical Development, Material Science, and other cross-functional teams to support the establishment of development strategies for new biological/cell products and supply materials to support pre-clinical studies and associated activities.
- Ability to use professional concepts in accordance with company objectives to solve complex bioprocessing problems in creative and effective ways.

- Advanced degree (BS, MS, PhD) in process engineering, immunology, cell biology, or equivalent. Technical training / certification is desirable.
- BS with 3-5 years, MS with 2-3 years and PhD with 1-2 years of experience in process development of gene or gene-modified products in a biotech, academic, or pharmaceutical setting.
- Core engineering background in bioprocessing of biologics, vaccines, and viral vectors (including working with viral vectors and cell therapy).
- Experience in biotechnology bioprocessing, gene and cell therapy process development, and/or GMP manufacturing.
- Hands-on experience working with bioreactors (upstream processing, scale down and scale up model) and downstream processing (e.g., filtration, chromatography, TFF) for lentivirus/AAV vectors, viral products, or biological entities.
- Experience handling the cell processing side for cell therapies, including mammalian cell culture, primary cell processing, and cellular expansion.
- Proven experience authoring SOPs/procedures for established and new engineering unit operations.
- Ability to transfer upstream and downstream bioprocesses to internal or external manufacturing sites.
- Ability to manage shifting priorities to meet critical deadlines in a fast-paced and dynamic, growing environment.
- Ability to work collaboratively with cross-functional engineering, manufacturing, and analytical teams.
- Detail-oriented with expertise in engineering problem solving and solid decision-making abilities.
