The core values that ground our work, guide our decisions, and connect us together:
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.
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
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
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
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
Represent Supply Chain in executive and cross-functional forums, influencing program strategy and decisions without relying on formal authority
Identify and lead cross-program or cross-commodity initiatives (e.g., process redesign, tooling/systems improvements, org-wide reporting standards) that raise the bar for the broader team
Maintain project tracking and reporting for the supply-chain portion of the project schedule and keep program status visible to stakeholders
Deliver regular, data-driven status updates on program and supply chain readiness to leadership, proactively flagging risks and schedule changes
Own relevant supply chain KPIs and drive process improvements that help the team scale program execution
Support supplier performance reporting and business reviews alongside Commodity/Category Managers
Education: Bachelor’s degree in Supply Chain Management, Engineering, Business Administration, or a related field; Master’s degree a plus
Experience: 10+ years in supply chain program management, NPI program management, or commodity/category management within a manufacturing or hardware environment, with a track record of leading full lifecycle transitions from NPI to mass production
Demonstrated ability to independently own the most complex, ambiguous, or highest-visibility programs, and to exercise sound judgment with minimal oversight
Track record mentoring or informally leading other Project Managers, and influencing program strategy and decisions across teams without formal authority
Working knowledge of NPI, EOL, and O&M program lifecycles, and of change-management processes
Skilled in supply chain risk assessment and resiliency planning, including proactive supplier follow-up on delivery issues and critical-component escalations
Strong communicator who can hold suppliers accountable while building collaborative, trust-based relationships across engineering, commodity management, and manufacturing partners, and who can present clearly and credibly to executive stakeholders
Hands-on experience with project tracking tools and standard supply chain/ERP systems; comfort analyzing supply chain data and performance metrics to inform decisions
Analytical experience or knowledge — comfort working with cost, schedule, or supplier performance data to build reporting and inform decisions — is a plus
Experience building or customizing AI-powered tools or applications (e.g., using Claude or similar large language model platforms) to automate analysis, reporting, or workflows is a plus
PMP (Project Management Professional), APICS/ASCM (CPIM or CSCP), or CPM/CPSM certification is a plus
