Plastics Sourcing Manager Jobs in Rochester, MI (NOW HIRING)

Own Supplier Performance. Drive Margin. Influence the Business.

This is

not a traditional procurement role

.

We are seeking a highly analytical, commercially driven leader to take ownership of enterprise-wide supplier performance and cost optimization across a multi-site manufacturing network. This role sits at the intersection of Supply Chain, Finance, Engineering, and Operations and plays a critical role in protecting margin, improving cost accuracy, and ensuring supply continuity.

If you’re energized by solving complex cost challenges, influencing cross-functional teams, and holding suppliers accountable to performance—you’ll thrive here.

About Us

We are a multi-site manufacturing organization serving leading OEMs across automotive, industrial, and consumer markets. With a strong focus on operational excellence, continuous improvement, and people-first leadership, we are building the next generation of supply chain performance.

Ready to Make an Impact?

If you're a high-performing sourcing or supply chain leader looking for broader scope, financial ownership, and real business influence, we’d love to connect.

Why This Role Stands Out

• Enterprise impact – Own Purchase Price Variance (PPV) and cost performance across multiple plants

• Direct EBITDA influence – Identify, drive, and deliver measurable margin improvements

• Cross-functional visibility – Regular interaction with Operations, Finance, and senior leadership

• Supplier leadership – Lead strategic supplier relationships, performance reviews, and accountability

• Build & improve systems – Shape how we manage cost, performance, and supplier strategy going forward

What You’ll Own

Drive Cost & Margin Performance

• Own and manage PPV performance across all sites

• Identify trends, risks, and opportunities to improve EBITDA and cash flow

• Lead root cause analysis and resolution of PO, invoice, and standard cost discrepancies

• Partner with Finance to strengthen cost accuracy and forecasting

Elevate Supplier Performance

• Establish and drive supplier accountability across cost, quality, delivery, and responsiveness

• Lead supplier business reviews with key strategic partners

• Build and enhance supplier scorecards and performance frameworks

• Strengthen relationships while holding suppliers to clear, measurable expectations

Lead Strategic Sourcing & Commercial Initiatives

• Execute strategic sourcing initiatives and commercial negotiations

• Identify and deliver cost savings and total cost optimization opportunities

• Support enterprise initiatives related to pricing, contracts, and supplier strategy

Strengthen Supply Continuity & Risk Management

• Identify and mitigate risks related to capacity, allocation, and supply disruption

• Develop and support dual sourcing and contingency strategies

• Monitor key market drivers (resins, logistics, macro trends) that impact cost and supply

Be a Cross-Functional Leader

• Act as the key liaison between Supply Chain, Operations, Finance, and AP

• Drive consistent cost management processes across all locations

• Participate in monthly operations and leadership reviews

• Support plant teams during escalations or supply disruptions

What You Bring

• 5+ years in strategic sourcing, procurement, cost analysis, or manufacturing finance

• Deep experience with PPV, standard costing, or variance analysis

• Strong analytical capability (advanced Excel, modeling, data interpretation)

• Proven ability to influence cross-functional stakeholders

• Experience working directly with strategic suppliers

• Track record of driving measurable business impact (cost savings, margin improvement)

Bonus Points For:

• Multi-site manufacturing experience

• Plastics or injection molding industry experience

• ERP systems (SAP, Plex, Oracle, IQMS)

• Exposure to rebate programs or cost recovery initiatives

What Success Looks Like

• PPV is predictable, controlled, and improving.

• Supplier performance is transparent and consistently measured.

• Cost discrepancies are quickly identified and resolved.

• Suppliers are accountable, aligned, and performance-driven.

• The business sees clear, measurable margin improvement.

Who Thrives Here

• You challenge the status quo and don’t accept “that’s how it’s always been done.”

• You bring a finance mindset into supply chain decisions.

• You are comfortable operating in ambiguity and complexity.

• You hold yourself and others accountable to results, not activity.

• You want a role where your work directly impacts the bottom line.
