Job Overview
We are seeking a Staff Supply Chain Project Manager to take on our most complex, ambiguous, and highest-visibility programs. In this senior individual-contributor role, you will own the supplier-facing side of program execution across New Product Introduction (NPI), End-of-Life (EOL), and Operations & Maintenance (O&M) scope — often across multiple programs or commodities at once — and act as the critical bridge between Engineering, Commodity/Category Management, Supplier Quality Engineering and external Suppliers. Beyond running your own programs, you will set the playbook other Project Managers follow: shaping process, mentoring less-senior PMs, and representing Supply Chain in cross-functional and executive forums. The ideal candidate operates with a high degree of autonomy, exercises sound judgment in ambiguous or unprecedented situations, and can influence outcomes across teams without direct authority.
Key Responsibilities
Program & Engineering Change Execution
-
Own supply-chain-side program management for the high visibility/high impact NPI, EOL, and O&M programs — driving plans, timelines, milestones, gate reviews, and budgets from early builds through production ramp and full transition to mass production
-
Partner with engineering and technical program counterparts on every engineering change or project, providing supplier readiness, cost, and schedule inputs while the technical owner maintains the engineering record
-
Lead supplier-facing execution of engineering changes: sharing EC and bill-of-materials data with suppliers, coordinating design-for-manufacturability feedback, and managing supplier schedules, tooling lead times, and capacity commitments
-
Drive transition planning (old part to new part at the supplier) and own obsolescence and disposition strategy for parts being phased out
Supply Chain Mapping & Materials Liaison
-
Develop and maintain the end-to-end supply chain map for each program you own — suppliers, procurement model, lead times, shipment/logistics plan, assembly/test model, and spares strategy
-
Serve as the supply chain liaison with contract manufacturers (CMs), key suppliers and manufacturers, coordinating materials readiness from prototype builds through volume ramp
-
Manage spend against program budgets, and drive production risk buys or strategic buffers when needed to protect the build schedule
Supplier Readiness & Risk Management
-
Own material readiness across program phases: proactively identify supply risks (lead-time changes, shortages, capacity constraints, design updates) and drive mitigation plans before they hit the build schedule
-
Own project cost impact analysis and cost reporting for the supply-chain portion of each program
-
Partner with tactical purchasing and commodity/category management resources, and support other commodities or cross-functional projects when workload allows
Leadership, Strategy & Process Ownership
-
Define and continuously improve the processes, templates, and best practices other Project Managers use to run supplier-facing program execution
-
Mentor and coach less-senior Project Managers, providing guidance on complex supplier situations, escalations, and program trade-offs
-
