Rack Design Engineer, Data Center - Memphis

The role

You will design the racks for AI compute clusters, owning the structure, power, cooling, service paths and physical integration of servers, switches, optics and liquid cooling. You will take designs from first sketch through production rate.

What you will do

• Own mechanical, structural and integration design of high-density AI compute racks and their chassis, frames, busbars, manifolds and cable/fiber raceways
• Integrate compute, networking, power distribution and liquid cooling into a buildable, serviceable, high-yield rack
• Design for the in-house manufacturing line, including DFM/DFA, fixtures, work instructions, first article and production ramp
• Close thermal, structural and power constraints with cooling, electrical, optical and network teams at the cluster level
• Drive vendor and in-house parts from concept to qualified production
• Work on the floor during prototype and production builds, debugging fit, leaks, cable dress, airflow and service time
• Produce and maintain CAD, BOMs, drawings and build documentation a line can run at volume
• Support cluster deployment of your racks, including first-site bring-up
• Partner with network, optical, electrical and firmware teams to deploy custom compute for inference and training

Required qualifications

• Bachelor's degree in mechanical engineering, aerospace engineering or an engineering discipline
• 2+ years of professional experience designing electromechanical hardware that was built and shipped (internship and project experience counts if the hardware was physically produced)
• Ability to lift up to 25 lbs. unassisted and work around active factory and datacenter hardware
• Willing to work extended hours and weekends as needed
• Willing to travel to manufacturing and datacenter sites

Nice to have

• Ownership of rack, chassis or similarly dense electromechanical products through prototype and production
• Experience with ethernet switching, networking, interconnects and high power distribution
• CAD fluency in SolidWorks, Creo or NX, with released drawings
• AI / HPC / GPU rack design: NVIDIA HGX/GB-class, custom OCP or equivalent liquid-cooled compute
• Liquid cooling design: cold plates, manifolds, CDUs, quick disconnects, leak detection and coolant compatibility
• High-power rack electrical integration: busbar, PDU, 48V, high-current 3-phase, grounding and service safety
• Cable and fiber physical design inside the rack (MPO/OSFP dress, bend radius, service loops)
• Experience taking a rack from NPI onto an in-house manufacturing line
• Thermal and structural analysis (CFD, FEA) used to make design decisions
• Time at a high-velocity hardware organization such as an AI/GPU cloud, custom compute, or OEM/ODM team

Before you apply

• Requires willingness to travel to manufacturing and datacenter sites
• Requires ability to lift up to 25 lbs. unassisted
