3D Mechanical Design Engineer (Data Center)

JOB TITLE: 3D Mechanical Design Engineer (Data Center)
LOCATION: Austin, TX
DURATION: 6 month contract to hire
RATE RANGE: Market Rate

POSITION SUMMARY:

This role commands ownership over the mechanical design lifecycle, from digital modeling and simulation to final documentation, for systems at both the server-rack and data-hall scale. The ideal candidate will bring a robust portfolio of experience in advanced CAD modeling, intricate liquid-cooling system design, and seamless integration of electrical components like power shelves, BBUs, and busbars.

RESPONSIBILITIES:

• Own the end-to-end mechanical design of 3D assemblies, including rack structures, brackets, rails, adapters, cooling manifolds, and fluid connectors, while ensuring the seamless integration of electrical components such as power shelves, busbars, and BBUs.
• Architect and validate high-performance liquid-cooling systems (e.g., CDMs), optimizing for flow efficiency, thermal performance, and material compatibility.
• Drive cross-functional collaboration with hardware, electrical, and facilities teams to achieve a fully integrated and optimized system design.
• Produce comprehensive design documentation, including detailed 3D models, 2D fabrication drawings, Bills of Materials (BOMs), and simulation reports. Capable of managing and optimizing this workflow using Claude code, Codex or equivalent to create skills.
• Lead the design review process and ensure all mechanical systems adhere to key industry standards (OCP, ASHRAE, EIA) throughout the entire product development lifecycle.
• Leverage advanced simulation to validate system performance by developing comprehensive digital-twin models, performing CFD analysis for thermal management, and conducting FEA to ensure structural integrity under operational loads.

QUALIFICATIONS:

• A bachelor’s or above in Mechanical Engineering or a related discipline.
• A minimum of 4 years of professional experience in mechanical design, specifically for data center or high-performance computing (HPC) infrastructure.
• Proficiency with a major 3D CAD platform (e.g., SolidWorks, CATIA) for designing complex mechanical assemblies.
• Demonstrated expertise in applying simulation tools to validate designs, including CFD for thermal analysis (e.g., Cadence Reality DC/Future Facilities) and FEA for structural and thermal stress evaluation.
• Comprehensive knowledge of data center subsystems, including the design and integration of liquid-cooling loops (CDMs, manifolds, connectors) and high-power electrical components (busbars, power shelves, BBUs).
• Understanding relevant industry standards (OCP, ASHRAE, EIA) and a proven ability to incorporate them into design practices.
• Exceptional communication skills, with a proven ability to lead technical projects and drive alignment across multidisciplinary teams.
• Capable of using Claude Code or Codex for optimize function and workflow.

BENEFITS SUMMARY: Individual compensation is determined by skills, qualifications, experience, and location. Compensation details listed in this posting reflect the base hourly rate or annual salary only, unless otherwise stated. In addition to base compensation, full-time roles are eligible for Medical, Dental, Vision, Commuter and 401K benefits with company matching.
