Senior GMP Maintenance Technician

Joining Moderna means advancing mRNA science to transform medicine. Work with exceptional global teams on a broad pipeline and build a career that makes a real difference for patients. Based at our new GMP Manufacturing facility in Harwell, UK, you will play a pivotal hands-on role in ensuring the availability, reliability, safety, and compliance of GMP and non-GMP process and support equipment. Operating as a sole contributor while serving as a technical escalation point for technicians and contractors, you will take ownership of equipment performance across your assigned area. You will combine deep maintenance expertise with structured troubleshooting, reliability engineering, CMMS ownership, and cGMP documentation to improve equipment uptime, safety, quality, and throughput. You will also work closely with Engineering and QA on capital and reliability initiatives, while supporting the 24/7 manufacturing operation through early, mid, occasional night shifts and callouts. This is an opportunity to shape maintenance excellence within a new GMP manufacturing environment—using Lean/6S, RCM, FMEA, RCA, digital-first approaches and emerging Generative AI tools to identify opportunities, strengthen technical knowledge, improve maintenance decision-making, and increase equipment effectiveness. Here's What You'll Do: Own equipment uptime and reliability within an assigned area, tracking performance against KPIs and driving improvements in equipment effectiveness. Lead structured troubleshooting and Root Cause Analysis (RCA) for complex equipment issues, acting as Deviation and CAPA owner and ensuring robust follow-through to resolution. Plan and coordinate preventative and corrective maintenance (PM/CM), including planned shutdown activities, while prioritizing and approving work orders within the CMMS. Author, review, and continuously improve maintenance procedures, maintenance plans, and job plans to ensure they remain effective and compliant with cGMP requirements. Act as a technical escalation point for technicians during shifts, lead daily maintenance huddles, and coach colleagues to strengthen technical capability. Lead small capital projects and reliability initiatives in partnership with Engineering and QA, including URS development, vendor selection, and FAT/SAT/IOQ support. Own CMMS data integrity for your area, including bills of materials, critical spares, and task lists, while developing spare-parts and equipment-criticality strategies. Manage external vendors and contractors, including permits to work, RAMS review, performance management, and supervision to ensure compliance with site GMP requirements and safety policies. Champion EHS by enforcing LOTO and safe systems of work, leading risk assessments and implementing safety improvements that eliminate hazards and reduce operational risk. Administer and perform work safely in accordance with site EHS policies and procedures, role-modelling Moderna's safety culture. Support regulatory inspections and internal audits as a maintenance SME and ensure observations and associated actions are closed in a timely manner. Support 24/7 operations as part of the team, providing on-shift support across early, mid, and occasional night shifts, together with callouts as required. Drive continuous improvement through Lean/6S, reliability engineering methodologies including RCM and FMEA, and digital-first approaches that eliminate waste and increase equipment effectiveness. Supervise and mentor contractors and technicians while remaining a sole contributor, providing technical direction and ensuring work meets GMP, maintenance, and safety expectations. Deliver On-the-Job Training (OJT) as a Qualified Trainer, developing training materials and verifying technical competency. Troubleshoot automated process equipment and PLC-controlled systems, alongside pneumatics, vacuum systems, pumps, valves, heat exchangers, mixing vessels, and utilities within the GMP manufacturing
