Karman Industries Karman Industries is a Torrance-based thermal technology company building the backbone for giga-scale AI infrastructure. Founded by a team from SpaceX, Rocket Lab, and GE, Karman is moving beyond legacy cooling with the launch of the HPU (Heat Processing Unit)—a new category of thermal architecture designed for the 100kW+ rack era. The HPU shrinks the exterior mechanical yard by up to 80% while reducing peak energy consumption by 10%+. Unlike traditional systems, the Karman HPU provides zero-water (WUE 0) cooling that ensures high-TDP GPUs and HBM4 memory stay at optimal thermal setpoints without throttling. Founded in 2024, we’re a fast-growing team of passionate professionals dedicated to making a tangible impact on the future of humanity. We design, build, and test real hardware, and we lead with ownership: you’ll own your work from concept to hardware and help shape how we scale. Our values are Ownership, Performance Excellence, Radical Transparency, and Customer-Centricity. Join us in our mission to transform the industry and contribute to a more sustainable world. Staff Power Electronics Engineer Karman Industries is seeking a highly motivated Sr. Power Electronics Engineer to join our team designing the next generation of heat processing systems. The candidate will lead the design, development, and qualification of a power conversion system that involves emerging high-voltage semiconductor technologies and cutting-edge electronics to enable the Karman Heat Processing Unit (HPU) and subsequent product development. The role will span across power distribution, control, sensing, and more. We value first‑principles thinking, hands‑on problem solving, accountability, and close collaboration with cross‑functional partners to deliver cohesive, high‑performance systems.
