Director of Supply Chain

Visa Sponsorship: Please note that we are unable to provide visa sponsorship for this position.Proper Voltage is unlocking the next generation of battery technology across robotics, data centers, and defense. We're building intelligent battery systems that make advanced chemistries (sodium-ion, lithium-titanate, lithium-silicon) work in products that were never designed for them. Humanoid robots can upgrade power systems without redesigning their entire platform. Data centers get safer, cheaper backup power. Drones and autonomous vehicles get higher energy density without lengthy integration cycles. If you want to work on hard engineering problems that matter (power systems that enable humanoid robots, AI infrastructure, and next-gen mobility) this is the place.Job Overview:The Director of Supply Chain & Procurement owns the full external supply ecosystem for Proper Voltage. They manage supplier relationships, negotiate commercial terms, drive CM onboarding and readiness, structure the procurement and logistics infrastructure, and ensure the company can build on schedule and at target cost.This person partners tightly with Engineering Ops, Systems (internal and external), and Finance to ensure supply risk is surfaced early, cost structures are known and controlled, and CMs are contractually aligned with quality, schedule, and margin expectations.You are looking for someone with direct electromechanical sourcing experience because your BOM includes cells, magnetics, PCBA, harnessing, mechanicals, plastics, metals, power electronics, and enclosures.ResponsibilitiesBuild and manage all supplier and CM relationships, including evaluation, selection, negotiation, and ongoing performance.Own all commercial terms with suppliers: pricing, lead times, MOQ structures, tooling, NRE, and production commitments.Establish procurement and material planning processes that support volume scale (0 -> 5K-> 100K units) across multiple product SKUs.Drive readiness for production builds with Engineering Ops: long-lead materials, capacity planning, and risk reviews.Ensure BOM stability, cost visibility, and cost reduction pathways across PCBAs, magnetics, cells, harnesses, and mechanicals.Oversee logistics for inbound materials and outbound finished goods, including freight, customs, and inventory buffers.Lead supply risk management: identify bottlenecks early, escalate appropriately, and ensure continuity across all programs.Required QualificationsProven success in leading complex electromechanical products through to volume production10 years supply chain, sourcing, or procurement leadership in electromechanical or power-related hardware.Strong experience with contract manufacturers and suppliers across PCBA, mechanicals, magnetics, and cells.Proven ability to scale from prototype to multi-thousand annual units, with experience building toward high-volume production.Deep understanding of BOM control, supplier negotiation, and material cost structures.Experience building procurement and material planning processes that support fast-growing hardware programs.Skilled working with engineering teams and understanding electromechanical systems.High ownership, strong commercial instincts, and the ability to operate independently.Preferred QualificationsPrior work in batteries, power electronics, robotics, or consumer hardware.Experience in high-volume environments (tens of thousands to hundreds of thousands of units).Familiarity with UL or certification-driven component requirements.Early-stage startup experience building supply chain processes from zero.Compensation & BenefitsSalary range: $165,000 - $210,000 depending on location, experience, and qualifications.
