• ROL/Kanban settings, and routings and pilot and roll out MRP/MPS to all codes.
• Plan and release production & purchase orders that meet customer demands.
• Manage and optimize capacity and inventory.
• Oversee cycle-counts, stockroom transactions and oversee root-cause analysis on variances.
• Create and set objectives, evaluate performance, and assist in building and leading cross-training.
• Collaborate with other departments such as purchasing, manufacturing, sales, and engineering to align schedules to resolve shortages.
• Support NPI.
• Drive resolution of material and process non-conformances.
• Manage the NPR workflow, lead collaborative root-cause analysis, and implement corrective actions.
• Manage revision changes and prototype gating and activate new part revisions, as well as shepherd prototypes through the approved workflow.
• Confirm all documentation, approvals, and BOM updates before full production.
• Drive continuous improvement, identify cost-reduction opportunities, streamline material flow, and lean/5S initiatives.
• Report KPIs (OTIF, inventory turns, schedule adherence) and present data-driven recommendations to senior leadership.

Requirements:

• Bachelor’s degree in Computer Science or Computer Engineering.
• 5 years in materials planning, production control, or supply-chain management within a manufacturing environment.
• Minimum of 5 years of hands-on experience in software engineering, with a proven track record of owning and maintaining production-level systems.
• Expertise in SQL and PostgreSQL, including query optimization, performance tuning, schema design, and database migrations.
• Proven success launching and optimizing MRP/MPS modules and governing master data.
• Proven proficiency with ERP systems data-analysis skills.
• Experience developing backend services and data pipelines with automated testing and CI/CD workflows in a Linux environment; proficient with Git and Docker.
