This individual will be expected to operate with strong ownership and accountability, driving both team performance and operational excellence while maintaining the highest standards of patient safety and product quality.

This is a hands‑on operational role requiring significant on‑the‑floor presence and direct Gemba of manufacturing areas during processing runs.

Key Responsibilities:

• Lead and manage daily cGMP manufacturing operations across cell and gene therapy programs, ensuring all activities are executed in compliance with approved batch records, SOPs, and applicable regulatory requirements.
• Build, develop, and retain a high-performing manufacturing team; hire, onboard, mentor, and conduct performance reviews for manufacturing specialists, senior associates, and supervisors.
• Champion a culture of quality, patient safety, and operational excellence across all manufacturing activities, ensuring team members always understand and uphold cGMP standards.
• Partner with MSAT to plan and execute Engineering Runs and Technology Transfer Runs for new client programs introduced to the site, supporting smooth transitions from process development to GMP manufacturing.
• Collaborate with Quality Assurance to ensure on-time closure of deviations, CAPAs, and change controls; serve as manufacturing owner for investigations and provide thorough, technically sound root cause analyses.
• Review and approve GMP-controlled documents including standard operating procedures, master batch records, material specifications, training materials, and validation protocols and reports.
• Develop and maintain a comprehensive training program for cGMP operations and manufacturing systems, ensuring all staff achieve and sustain the competency level required for multi-product clinical manufacturing.
• Manage manufacturing scheduling, ensuring people, facility, equipment, materials, and documentation are aligned and available to support program timelines and site capacity requirements.
• Oversee and provide direct on-the-floor operational support during all manufacturing runs and processing activities; maintain regular Gemba walks through manufacturing suites and support areas to observe operations firsthand, identify improvement opportunities, and ensure compliance with procedures and cGMP practices.
• Drive continuous improvement initiatives aimed at increasing right-first-time performance, reducing operational cycle times, and improving overall manufacturing efficiency.
• Develop, track, and report departmental KPIs; present operational performance updates and contribute to the development of annual department goals and budgets.
• Support capacity planning for clinical and commercial manufacturing campaigns; proactively identify and elevate resourcing or scheduling risks that could impact client program delivery.
• Build and maintain effective cross‑functional partnerships with Quality, Supply Chain, MSAT, EHS, Facilities and Engineering, and client teams to ensure alignment and seamless execution across all operational activities.
• Support regulatory inspection readiness activities including internal audits, mock inspections, and preparation of manufacturing areas and documentation for FDA, EMA, or other agency inspections.

Supervisory Responsibilities:

• Hire, mentor, and develop exceptional manufacturing talent at all levels, from entry-level associates to senior supervisors.
• Conduct regular performance reviews and identify opportunities for career growth, skills development, and advancement.
• Foster a culture of collaboration, cross‑functional inclusion, execution excellence, and effective communication to build a high-performing manufacturing team.
• Provide clear direction, coaching, and accountability to direct reports; resolve team conflicts and performance issues in a timely and constructive manner.
