MES Engineer

Legend Biotech is a global biotechnology company dedicated to treating life‑threatening diseases. Headquartered in Somerset, New Jersey, we develop advanced cell therapies across diverse technology platforms—including autologous and allogenic chimeric antigen receptor (CAR‑T), T‑cell receptor (TCR‑T), and natural killer (NK) cell‑based immunotherapy.

The MES Engineer will be part of the Manufacturing Excellence team, reporting to the Manufacturing Execution Systems Lead. The role will be responsible for E  development and administration at the Raritan site, supporting production processing while liaising with functions such as Tech Support, Process Improvement, Validation, Supply Chain, Operations, QA, Reg CMC, and IT. The engineer will support electronic batch record (E ) updates, system improvements, process and facility updates, and qualification activities associated with MES (PAS‑X).

• Coordinate with other departments to gather user requirements, gauge effort, and deliver robust, right‑first‑time E  designs.
• Participate in design testing, release planning, and demos with partners.
• Serve as a subject matter expert of MES for CAR‑T and site initiatives requiring MES enhancements.
• Coordinate MES updates with other supply chain systems (ERP, eLIMs, etc.).
• Coordinate and execute MES validation activities according to the Software Development Lifecycle (e.g., commissioning test plans (CTP), installation/operational qualification (IOQ)).
• Define standardizations and update documentation (e.g., SOPs, WIs, technical & design specifications, and qualification protocols) with alignment to global procedures.
• Act as a site MES SME to support quality investigations, corrections, and QMS records.
• Build the site readiness of MES for FDA and/or other regulatory audits/inspections.
• Train Manufacturing Excellence on MES utilization and ensure that Manufacturing Excellence properly assesses updates and impact.
