Senior Buyer/Planner

Are you a supply chain professional who thrives on complexity, loves working close to the factory floor, and can navigate a cross-border operation without missing a beat? Advantage Components is looking for an experienced Buyer/Planner to take full ownership of our purchasing and production planning function across our US and Mexico facilities.

About Us

Advantage Components, Inc. is a precision wire harness manufacturer with production facilities in Joliet, IL and Fresnillo, Zacatecas, Mexico. With deep expertise in electro-mechanical assemblies, we serve OEM customers across industrial and related markets. Our Mexico facility accounts for a growing share of our production volume, making cross-border collaboration central to everything we do.

The Opportunity

This is a high-impact, hands-on role at the intersection of purchasing, planning, and operations. You will own the end-to-end supply chain for both plants — building supplier relationships, driving on-time delivery, managing USMCA compliance, and leading a small team of two Junior Buyers. The previous Buyer/Planner built this function over nine years; we are looking for someone ready to step in, strengthen what works, and take it to the next level.

What You’ll Do

• Run production planning for both Joliet and Fresnillo using lean/pull-based techniques — shop orders, Kanbans, demand forecasting, and schedule management.
• Own all purchasing activity: raw materials, components, and supplies. Consolidate orders, manage freight costs, and ensure 95%+ fill rates.
• Manage the cross-border material plan and USMCA compliance for all US-Mexico shipments.
• Partner daily with Sales, Customer Service, Engineering, and Plant Operations to lock in delivery commitments and resolve supply issues fast.
• Maintain item master integrity: BOM accuracy, cost fields, lead times, and planning parameters.
• Drive inventory turns improvement through Kanban optimization and safety-stock rightsizing.
• Supervise and develop two Junior Buyers — assign work, coach for growth, and build a high-performing team.

What We’re Looking For

You’ll need:

• 5+ years of purchasing and/or production planning in a manufacturing environment.
• Real-world experience in a lean organization — Kanban, continuous improvement, pull scheduling.
• Working knowledge of USMCA/NAFTA compliance and US-Mexico cross-border logistics.
• ERP/MRP proficiency and strong Excel skills.
• A bachelor’s degree in Supply Chain, Business, Operations, or equivalent experience preferred.
• Clear, confident communication skills and the ability to collaborate across departments and cultures.

Big plus if you have:

• Experience in wire harness, cable assembly, or electro-mechanical manufacturing.
• Bilingual English/Spanish — our Fresnillo team will love you for it.
• APICS CPIM or CSCP certification.
