About GTI Energy

GTI Energy, a division of GTI Fabrication, is a leader in industrial modular fabrication, serving energy, defense, and heavy industrial markets. With facilities in Arizona and New York, we specialize in high-volume, mission-critical systems such as modular data centers, enclosed battery systems, and energy storage devices. We are expanding rapidly and seeking a Master Scheduler to bring precision, accountability, and operational discipline to our production environment.

Position Overview

The Master Production Scheduler will be responsible for developing, maintaining, and executing the master production schedule (MPS), ensuring alignment across customer demand, materials availability, production capacity, and shop-floor execution systems. This individual will own every detail of what GTI produces—across materials, labor, equipment, and timelines—while balancing efficiency, cost, and delivery commitments.

This role requires a highly analytical, detail-driven leader who thrives in fast-paced, high-growth manufacturing environments and has experience coordinating across engineering, procurement, supply chain, and plant operations.

Key Responsibilities

Master Scheduling & Production Planning

• Develop, publish, and manage the Master Production Schedule (MPS) to meet customer demand and internal capacity constraints.
• Translate sales forecasts, customer orders, and inventory targets into actionable production schedules.
• Synchronize materials, labor, equipment, and MES/ERP data to support on-time delivery and minimize bottlenecks.
• Coordinate with Engineering on new product introductions (NPI) to ensure seamless production ramp-ups.

Capacity & Resource Planning

• Conduct capacity analysis for labor, machines, and work centers across multiple production lines.
• Model and forecast mid/long-term production requirements to support plant expansions or equipment investments.
• Align plant-level scheduling with broader supply chain, MES, and logistics strategies.

MES & ERP Integration

• Utilize Manufacturing Execution Systems (MES) to track real-time production data, machine utilization, and labor performance.
• Integrate MES with ERP/MRP systems (NetSuite preferred, SAP/Oracle/JD Edwards acceptable) to maintain end-to-end visibility of orders, materials, and schedule execution.
• Ensure schedule adherence by monitoring shop-floor performance through MES dashboards and reports.
• Partner with IT, engineering, and operations to configure MES workflows for new products and plant processes.

Materials & Inventory Alignment

• Partner with procurement and supply chain teams to ensure materials availability supports scheduled production.
• Identify and resolve shortages, excesses, or disruptions by proactively re-prioritizing schedules.
• Maintain ERP and MES data integrity to support accurate planning and execution.

Cross-Functional Collaboration

• Serve as the central communication hub for production priorities—working closely with Engineering, Quality, Procurement, and Plant Operations.
• Lead weekly S&OP (Sales & Operations Planning) or production review meetings to align all stakeholders.
• Provide visibility into schedule performance, risks, and opportunities.

Performance & Continuous Improvement

• Track KPIs such as on-time delivery, production attainment, first-pass yield, inventory turns, and MES-driven efficiency metrics.
• Drive schedule adherence and create mitigation plans for deviations.
• Champion Lean, Six Sigma, and MES-enabled continuous improvement initiatives to reduce lead times and increase throughput.

Required Qualifications

• Bachelor’s degree in Supply Chain, Operations, Industrial Engineering, or related field.
• 7 years of experience in master scheduling, production planning, or supply chain in a high-volume manufacturing environment.
• Strong proficiency with ERP/MRP systems (NetSuite preferred, SAP/Oracle/JD Edwards acceptable).
• Hands-on experience with Manufacturing Execution Systems (MES) to manage shop-floor execution.
• Solid understanding of capacity planning, materials requirements planning, and production workflows.
• Advanced Excel and data analysis skills (pivot tables, VLOOKUPs, formulas, dashboards).
• Excellent problem-solving, communication, and presentation skills.

Preferred Qualifications

• APICS CPIM (Certified in Production & Inventory Management) or CSCP certification.
• Experience integrating MES with ERP to improve real-time scheduling accuracy.
• Familiarity with ISO 9001 quality systems and compliance requirements.
• Knowledge of Lean Manufacturing, Six Sigma, and Theory of Constraints (TOC) principles.
• Experience in industries such as automotive, aerospace, heavy equipment, or industrial fabrication.

Why Join GTI?

• Be the owner of scheduling and MES-driven production execution at a high-growth company impacting energy, defense, and infrastructure.
• Competitive salary and benefits package.
• Opportunity to work with cross-functional leaders and advanced MES/ERP systems.
• Lead the planning discipline for a company that values speed, accountability, and operational excellence.
