You'll own rack design for high-density AI compute systems, from initial concept through production, managing mechanical structure, power distribution, cooling integration, and manufacturability. You need a bachelor's degree in mechanical or aerospace engineering and 2+ years designing electromechanical hardware that shipped to production. Strong CAD skills, experience with liquid cooling and high-power electrical systems, and familiarity with HPC/GPU rack design are essential. The role is based in Memphis and requires willingness to travel to manufacturing and datacenter sites and work extended hours during design releases and deployments.
Written from this posting by Neural Jobs AI. The full description is below.
SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.
The Data Center Engineering team designs training and inference compute clusters from first principles, pushing thermal, electrical, and optical systems to the limit of physics. We operate as a highly cross disciplinary team comprised of mechanical, electrical, optical, and software engineers, all working to maximize the efficiency, reliability, and deployment speed of terrestrial computing to serve rapidly scaling demand.
This team owns compute architecture, datacenter network design, rack builds, connectivity, in-house design of our own computers, and the manufacturing line that builds that compute. As a Rack Design Engineer, you will own the rack as a product: structure, power, cooling, service paths, and the physical integration of servers, switches, optics, and liquid cooling from first sketch through production rate.
