What this posting asks for

Level: Mid level — The posting asks for 2+ years of experience.

Main responsibilities

• Own mechanical, structural, and integration design of high-density AI compute racks and associated chassis, frames, busbars, manifolds, and cable/fiber raceways
• Integrate compute, networking, power distribution, and liquid cooling into a buildable, serviceable, high-yield rack architecture
• Design for the in-house manufacturing line: DFM/DFA, fixtures, work instructions, incoming inspection, first article, and production ramp
• Close thermal, structural, and power constraints with cooling, electrical, optical, and network counterparts at the cluster level (CDUs, cold plates, quick d…
• Drive vendor and in-house parts from concept to qualified production, including sheet metal, extrusions, busbar, manifolds, cable management, and rack access…
• Stand on the floor during prototype and production builds: debug fit, leak, cable dress, airflow/liquid balance, and service time; fold issues into the next …
• Produce and maintain CAD, BOMs, drawings, and build documentation that a line can run at volume
• Support cluster deployment of the racks you design, including first-site bring-up and feedback into the next hardware generation
• Partner with network, optical, electrical, and firmware teams to deploy custom compute for inference and training across SpaceX programs
• Bachelor’s degree in mechanical engineering, aerospace engineering, or another engineering discipline

Competencies an interviewer will look for

• Technical skill Core
  In the posting: “We operate as a highly cross disciplinary team comprised of mechanical, electrical, optical, and software engineers, all working to maximize the efficiency, …” · “This team owns compute architecture, datacenter network design, rack builds, connectivity, in-house design of our own computers, and the manufacturing line t…” · “Integrate compute, networking, power distribution, and liquid cooling into a buildable, serviceable, high-yield rack architecture”
  Show it by: Names the tools, languages or systems used and how; Explains a technical choice and its trade-off.
• Ownership and accountability Core
  In the posting: “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, o…” · “Ownership of rack, chassis, or similarly dense electromechanical products through prototype and production” · “Time at a high-velocity hardware organization: AI/GPU cloud, custom compute, or an OEM/ODM team that owned the product end to end”
  Show it by: Takes a task from start to finish without being chased; Owns a mistake and what was changed after it.
• Planning and organisation Core
  In the posting: “Time at a high-velocity hardware organization: AI/GPU cloud, custom compute, or an OEM/ODM team that owned the product end to end” · “Applicants wishing to view a copy of SpaceX’s Affirmative Action Plan for veterans and individuals with disabilities, or applicants requiring reasonable acco…”
  Show it by: Shows how priorities were set when everything was urgent; Mentions deadlines met and how.
• Data and analysis Core
  In the posting: “Experience or background in ethernet switching, networking, interconnects, high power distribution, and other relevant data center technologies” · “Thermal and structural analysis (CFD, FEA) used to make a design decision”
  Show it by: Uses a number to describe the situation or the result; Explains what the data showed and what was done with it.
• Stakeholder management Core
  In the posting: “Drive vendor and in-house parts from concept to qualified production, including sheet metal, extrusions, busbar, manifolds, cable management, and rack access…” · “employment with SpaceX is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, ge…”
  Show it by: Shows how they aligned people with different goals; Explains how they handled a 'no' from someone senior.
• Communication Supporting
  In the posting: “Produce and maintain CAD, BOMs, drawings, and build documentation that a line can run at volume”
  Show it by: Adapts the message to the listener; Gives an example of explaining something clearly in writing or speech.
• Teamwork and collaboration Supporting
  In the posting: “Partner with network, optical, electrical, and firmware teams to deploy custom compute for inference and training across SpaceX programs”
  Show it by: Says what they did inside a team, not only what 'we' did; Shows how a disagreement was handled.
• Attention to detail and quality Supporting
  In the posting: “High-power rack electrical integration: busbar, PDU, 48V, high-current 3-phase, grounding, and service safety”
  Show it by: Gives an example of an error caught before it caused harm; Names the check or standard they used.
