ABOUT THE ROLE

You don't just keep Plex running — you shape how it works. Security models, workflows, custom SQL reports, VisionPlex screens, EDI integrations — you design and own the configurations that turn Plex into a genuine competitive advantage for the business.

When the system isn't delivering for the plant, you're the one who sees it first and fixes it. You bring structure where there's ambiguity, reliability where there's been guesswork, and capability where people have been working around limitations for years.

This is a high-visibility role at the center of a multi-year supply chain transformation. You'll be a primary driver of ERP utilization across Powertrain Americas — partnering directly with supply chain leadership and plant operations to close the gap between what Plex can do and what the business actually needs.

The goal is straightforward but meaningful: accurate data, clean configurations, optimized workflows, and a system people trust to make decisions. If you've ever wanted to build something that lasts — not just patch it — this is the role.

KEY RESPONSIBILITIES

• Serve as Primary Plex ERP Administrator for multiple Powertrain Americas manufacturing plants and corporate business functions
• Configure Supply Chain Processes and standards.
• Provide Supply Chain support via the internal Plex ticket system, resolving complex issues across: Inventory, Production, Procurement, Job Management, Parts, Quality, Maintenance, HR, Accounting, and Workflows.
• Support demand planning, supply planning, MRP, and Procure-to-Pay business process cycles within Plex
• Maintain MRP parameters — safety stock, lead times, lot sizes, MRP types, reorder points — with documented, periodic review cadences
• Partner with the business leaders to align ERP configuration with global supply chain standards.
• Serve as the region representative in Tenneco's supply chain data governance initiatives.

JOB REQUIREMENTS

• Bachelor’s degree in Supply Chain, Information Systems, Engineering, Industrial Operations, or a related field.
• 5+ years of hands-on Supply Chain Plex ERP experience in a manufacturing environment. Multi-site or regional administration experience is strongly preferred. Deep familiarity with Plex modules: Inventory, Production, Procurement, MRP, Job Management.
• Deep proficiency in Plex ERP — security model, module configuration, workflow design, and SQL/VisionPlex reporting. Multi-site administration experience preferred.
• Experience configuring and managing EDI trading partner integrations within Plex, including mailbox creation, transaction troubleshooting, and partner onboarding. Familiarity with EDI standards (ANSI X12 or EDIFACT) a plus.
• Track record of improving ERP data quality through systematic audit programs, governance processes, and root cause elimination — not just one-time data cleanup. Understanding of how plant-level ERP data feeds enterprise analytics platforms.
• Travel requirements 30-65% of the time.
