Supply Planning About Us: At Tenneco, we're on a mission. Guided by our Core Values and a winning mindset, we are committed to becoming the most trusted partner, manufacturer, and distributor in the transportation industry. What drives us? Our people are passionate changemakers who bring energy, dedication, and innovation to everything they do. In this role, you will own the plant system that converts production demand into reliable supplier requirements, material availability, and controlled raw-material inventory. You will establish disciplined MRP execution, resolve exceptions before they disrupt production, coordinate inbound schedules, and lead supplier recovery using the P3 Integrated Supply Chain standards. Your work will connect Planning, Procurement, Logistics, Customs, Production, and Finance through one visible operating rhythm. Who are you? - Inbound Planning Expert: Translate demand into executable supplier requirements using MRP, governed ERP parameters, lead times, MOQs, safety stock, coverage, and supplier schedules without uncontrolled offline workarounds. - Material Availability Owner: Maintain fact-based shortage and critical-material risk visibility; identify constraints early, define containment and recovery, assign owners and due dates, and escalate before production or delivery is affected. - Inventory and Working-Capital Operator: Balance service, risk, and cash; set and challenge raw-material targets, optimize safety stock and order policies, reduce excess and obsolete inventory, and avoid reductions that create supply exposure. - Supplier Execution Partner: Establish a clear cadence for capacity, commitments, ASN discipline, OTD/OTIF, corrective actions, and recovery across external and intercompany suppliers. - Data-Driven Problem Solver: Use MRP exceptions, inventory coverage, supplier performance, schedule adherence, and premium freight signals to identify root causes and drive permanent countermeasures. Who will you set to win, and how will you do that? - Production and Customer Planning: Provide a credible material plan, clear shortage visibility, and recovery decisions aligned to the production schedule and customer priorities. - Procurement and Supplier Development: Provide accurate supplier requirements, performance evidence, capacity risks, and structured escalation needed to improve supplier execution. - Transportation and Customs: Align pickup schedules, carrier capacity, routes, documentation, and clearance priorities to protect inbound material flow. - Finance and Plant Leadership: Deliver transparent inventory, risk, and recovery information that supports working-capital and operational decisions. - Suppliers: Provide stable schedules, clear expectations, timely escalation, and disciplined follow-through. What's going to be your legacy? Reliable Material Availability: A plant where shortages are identified early, recovery is owned, and production is protected through disciplined planning rather than recurring firefighting. MRP as the Operating Standard: A sustained process where planning parameters are governed, MRP runs on cadence, exceptions are closed daily, and system outputs drive action. Healthy Raw-Material Inventory: Lower excess and obsolescence while maintaining the coverage required to support production and customer service. Accountable Supplier Performance: A visible
