Mechanical Engineer, Electronics Packaging

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. Mechanical Engineer, Electronics Packaging Karman Industries is seeking a highly motivated electronics packaging expert to join our team designing the next generation of heat processing systems. The candidate will lead the design, development, and qualification of packaging systems for power conversion devices, high-frequency transformers, medium voltage electrical machines, and cutting-edge medium voltage electronics to enable the Karman Heat Processing Unit (HPU) and subsequent product development. The role will include system level design with a view to manufacturing, addressing mounting, isolation, durability, heat transfer, and more. We are a team that relies on strong first principles approach, working together to deliver a cohesively developed system.
