Master Scheduler

At Nextern, we inspire with passion, impact with significance, and act with integrity.. Nextern partners with OEMs, clinicians, and innovators to design, develop, and manufacture world-class medical devices across the full product lifecycle. From single-use disposables to fully integrated systems to precision components, our teams work as an extension of yours to solve patient needs and improve lives worldwide. The Master Scheduler is a key member of Nextern’s Supply Chain organization, responsible for developing, maintaining, and executing the master production schedule (MPS) across multiple concurrent client programs at Nextern’s US medical device contract development and manufacturing organization (CDMO) site. This individual translates client demand, forecasts, and contractual delivery commitments into an achievable, capacity-balanced production plan — synchronizing manufacturing, materials, and quality resources to protect on-time, in-full delivery. The Master Scheduler serves as the critical link between Program Management, Procurement, Manufacturing, and Quality, ensuring the schedule reflects real-world constraints such as component lead times, equipment capacity, and regulatory holds while meeting the delivery, quality, and cost performance expected by world-class medical device clients. Responsibilities: Develop, publish, and maintain the site master production schedule (MPS) across multiple client programs and product lines, balancing demand, capacity, and inventory targets. Convert client forecasts, purchase orders, and contractual delivery commitments into an executable, capacity-balanced build plan within the site’s ERP/MRP system. Run and interpret MRP outputs; release, reschedule, and prioritize work orders to align material availability, labor, and equipment capacity with the MPS. Maintain accurate planning parameters — lead times, lot sizes, safety stock, BOM and routing data — to ensure MRP recommendations remain reliable. Manage the planning time fence and change control process, evaluating schedule impact before committing new orders, engineering changes, or expedite requests. Model and monitor production capacity by line and work center; identify capacity gaps and constraints and propose recovery options such as overtime, resequencing, or subcontracting. Partner with Manufacturing and NPI to translate development and pilot-scale programs into full commercial-scale production schedules. Support rough-cut capacity planning and scenario (“what-if”) analysis for new client programs, demand changes, and capital equipment decisions. Escalate material or capacity shortfalls that put client delivery commitments at risk, with clear recovery plans and revised dates. Serve as the scheduling point of contact for Program Management, Procurement, Manufacturing, and Quality on delivery status, risks, and priorities. Participate in daily tier meetings and weekly operations/S&OP reviews, providing data-driven visibility into…
