What are the responsibilities and job description for the Production Planner position at Gibraltar Fabrication?
The Production Planner is responsible for developing and executing a 1012 week rolling Master Production Schedule within a hybrid manufacturing environment that includes both Build-to-Order (BTO) engineered steel fabrication and Assemble-to-Order (ATO) standardized product lines.
This role ensures on-time delivery, optimized capacity utilization, disciplined job release, and effective inventory management. The Planner partners cross-functionally with Sales, Engineering, Procurement, and Fabrication to align backlog execution with capacity constraints while maintaining control of working capital and service levels.
What Youll Do
- Master Production Scheduling & Forecast Management
- Own and maintain a live 1012 week rolling Master Production Schedule.
- Schedule confirmed customer orders with approved submittals and validated data.
- Establish and manage frozen scheduling zones to protect execution stability.
- Balance backlog demand with labor and equipment capacity.
- Capacity Planning & Constraint Management
- Model labor hours and machine capacity across key work centers (laser, press brake, machining, weld, coating, assembly, shipping).
- Allocate shared capacity between BTO and ATO product families.
- Protect bottleneck operations, particularly welding and coating.
- Monitor and prevent excess WIP ahead of constraint areas.
- Adjust capacity allocation based on backlog mix and demand trends.
- Inventory & ATO Replenishment Planning
- Manage replenishment planning for standardized product lines.
- Establish and maintain safety stock levels, min/max parameters, batch sizing, and inventory turn targets.
- Coordinate production runs to support inventory needs without disrupting BTO commitments.
- Optimize working capital while maintaining target fill rates and avoiding stockouts.
- Job Release Governance (BTO)
- Enforce disciplined release criteria ensuring:
- Approved submittals
- Validated BOMs and routings
- Secured long-lead materials
- Confirmed coating/galvanizing plans
- Allocated capacity within the schedule
- Material availability
- Prevent partial or premature job releases that create instability.
- Sales & Operations Alignment
- Participate in weekly production and S&OP meetings.
- Validate delivery commitments prior to customer promise dates.
- Provide realistic ship dates during quoting.
- Model capacity impact of major pending bids and backlog changes.
- KPI & Performance Ownership
- Monitor and report performance metrics, including:
- BTO Metrics:
- On-time delivery
- Schedule adherence within frozen zone
- Constraint utilization
- WIP aging
- Expedite frequency
- ATO Metrics:
- Inventory turns
- Fill rate and stockout rate
- Replenishment cycle time
- Working capital tied to inventory
- Continuous Improvement
- Improve forecast accuracy and planning discipline.
- Reduce lead times and WIP levels.
- Enhance ERP data integrity (BOMs, routings, lead times).
- Develop scalable planning systems to support growth.
What Youll Bring
- Strong understanding of steel fabrication processes and workflow sequencing.
- Demonstrated experience managing rolling production forecasts in complex manufacturing environments.
- Proficiency in ERP/MRP systems and capacity modeling.
- Analytical mindset with the ability to balance service, throughput, and working capital objectives.
- Ability to influence cross-functional stakeholders and enforce scheduling discipline.
- Advanced Excel and data analysis capabilities.
Education | Experience
- 5-7 years of production planning or scheduling experience in steel fabrication or heavy manufacturing.
- Experience in hybrid BTO and ATO production environments.
- Proven experience managing 812 week rolling production schedules.
- Strong capacity planning and constraint management expertise.
- APICS CPIM certification or equivalent supply chain credential preferred .
- Experience in heavy steel fabrication operations.
- Experience supporting large-scale manufacturing operations ($100M revenue).
- Ability to work in the United States without sponsorship.
