Senior Buyer, Electronics & Power Systems

Karman Industries Gardena, CA Founded in 2024 and headquartered in Gardena, California, Karman Industries is at the forefront of revolutionizing industrial thermal energy. Our mission is to electrify global thermal systems across data centers, manufacturing, and energy industries. Karman is developing the revolutionary Heat Processing Unit (HPU) to reinvent thermal handling for giga-scale data centers & AI factories. The HPU is built around a supercritical CO2 chiller system utilizing a high-speed electrically driven turbomachinery core. Our system aims to reduce energy consumption in data center thermal management by greater than 25% and increase energy density by 10x. At Karman Industries, we are committed to fostering a dynamic and inclusive work environment where innovation thrives. Our team is composed of passionate professionals dedicated to making a tangible impact on the future of industrial manufacturing. Join us in our mission to transform the industry and contribute to a more sustainable world. Senior Buyer, Electronics & Power Systems We are building the supply chain behind the HPU, and its power electronics and high-speed motors are the long-lead items most likely to stop a build. You will own supply for electronics and power systems end to end: category strategy, sourcing, supplier performance, and supply continuity for PCBAs, power semiconductors, solid-state transformer (SST) hardware, high-speed electric motors, sensors, connectors, and wire harnesses. You will work directly with Engineering and Production to turn BOMs and build plans into on-time, on-cost deliveries, and to surface supply risk before it becomes a line-down. Key Responsibilities: Category strategy and sourcing Own the electronics and power systems category strategy: supplier selection, dual- and second-source plans, consolidation, and long-term agreements Run RFQs and competitive bids; compare total landed cost, lead time, MOQ, and quality history, then recommend awards Negotiate pricing, payment terms, lead times, and capacity commitments with manufacturers, authorized distributors, and EMS, PCB, and custom-build vendors Drive cost-down through should-cost analysis, volume leverage, and design-to-cost input to Engineering; report savings against a baseline Power electronics and motors Source power semiconductors (SiC and GaN devices, IGBT modules), gate drivers, and medium-voltage-rated components; manage allocation, capacity commitments, and long-term supply agreements with device makers Source SST subassemblies and materials: high-frequency magnetics, DC-link and film capacitors, insulation systems, bushings, and cooling plates Source high-speed motor components and builds: stators and windings, rotors, permanent magnets, electrical steel laminations, magnet wire, and bearings; manage build-to-print and custom-wound suppliers Source inverters, motor drives, encoders, resolvers, and sensors Manage raw-material exposure (copper, rare earths, electrical steel) with index-based pricing or hedged terms where possible Supplier management and qualification Build and maintain the approved manufacturer and approved vendor lists with Engineering and Quality Coordinate supplier qualification with Engineering and Quality: first article inspection, sample builds, high-pot and insulation testing, and rotor balancing records Run supplier scorecards covering on-time delivery, quality, and cost; lead quarterly business reviews, corrective actions, and improvement plans Planning and supply continuity Translate production forecasts and BOMs into purchase plans; review MRP output and set buy, safety stock, and buffer strategies for long-lead parts Join supply and demand planning with Production and Program teams; give accurate supply status each week Track open POs, expedite late deliveries, and escalate shortages with a recovery plan Supply risk and compliance Monitor EOL and PCN notices, flag single-source parts, and drive last-time-buy and second-source dec…
