Senior Material Planning Program Manager, Supply Chain

Amperesand is building next-generation power infrastructure systems for Data Centers, EV charging platforms, and future energy applications. Our systems combine advanced power electronics, embedded controls, and scalable energy architectures to rethink how power is converted, controlled, and deployed.

About the Role

Every SST we ship depends on hundreds of components arriving on time, in the right quantities - across a supply base that's ramping as fast as our product roadmap. This role sits inside our Supply Chain organization and owns the planning discipline that keeps that possible: translating engineering schedules and customer demand signals into a material plan the whole company can build against.

What You’ll do

Material Planning & Execution

• Own end-to-end material planning across our BOMs - demand/supply reconciliation, buffer and safety-stock strategy, and purchase prioritization that keeps pace with engineering change
• Translate program schedules into concrete, current material plans; know at any given moment what's on track, what's at risk, and what needs to move
• Continuously monitor supplier lead times, MOQs, allocation, and other risk

Supply Readiness & Risk

• Partner with GSMs and SIEs to close gaps before they threaten a build
• Track program-level clear-to-build status and drive the cross-functional work to unblock it before it becomes a hard stop
• Own the material and inventory impact of supply impacting ECOs from assessment through implementation - quantifying exposure, and keeping the program informed of what's changing and why it matters

Systems & Scale

• Work with software team to build the planning tools, dashboards, and processes - spanning PLM, ERP, and MRP - that give Supply Chain, Engineering, and Manufacturing one shared, trustworthy view of material readiness
• Design for the business we're scaling, not just the build in front of us.

What You’ll bring

• 5-8+ years in material planning, program management, or supply chain roles supporting complex hardware, with hands-on ownership of large, multi-hundred-line BOMs from development through ramp
• Strong working knowledge of demand/supply planning, supplier readiness, and the cost/material impact of quality and engineering changes
• Experience standing up planning or supply-readiness processes from scratch - not just operating inside systems someone else built
• A track record of spotting problems weeks before they land, and driving resolution across engineering, sourcing, and manufacturing teams
• Comfort with ambiguity and a genuine interest in shaping how a fast-growing hardware company plans and scales
• BS in Supply Chain, Data Analytics, or a related field

Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.

Onsite Collaboration Rationale:

Given the highly collaborative and cross-functional nature of hardware, embedded systems, and product development, in-person partnership across engineering and product teams is critical to enabling rapid execution, technical alignment, and successful development outcomes.

Why Join Amperesand

• Work on next-generation power infrastructure systems
• High ownership and visibility
• Cross-functional collaboration
• Opportunity to shape future products and infrastructure
• Fast-moving startup environment
