Master Scheduler

ARSAN International Consulting Group | Full time

York, United States | Posted on 01/16/2026

The Master Scheduler is a senior manufacturing planning leader responsible for bringing discipline, realism, and credibility to the Master Production Schedule (MPS) within a complex manufacturing environment. This role owns end-to-end schedule governance and serves as the single point of accountability for aligning customer demand, material availability, production capacity, and inventory objectives.

Beyond technical scheduling, this position is a planning leadership role. The Master Scheduler leads and develops a team of Planner Buyers, drives cross-functional decision-making, and acts as a trusted operational authority across Manufacturing, Supply Chain, Engineering, Quality, and Commercial teams. Success in this role requires the confidence to challenge assumptions, surface risks early, and make data-driven decisions under pressure.

This is not a transactional planning position. It is a senior execution role critical to delivery performance, inventory health, and operational credibility.

Applicants must have legal authorization to work in the United States.
