3D Design Engineer

Job Description

3D Design Engineer - Data Center Infrastructure | Fremont, CA (Contract)

Design next-generation liquid-cooled data center infrastructure for a leading electric vehicle and technology innovator, applying advanced CAD modeling and thermal simulation to power cutting-edge AI and computing systems.

About the Role : We're seeking an experienced 3D Design Engineer to drive mechanical architecture for our client's advanced data center operations in the automotive technology and AI sector. This 6-month contract (with extension potential) offers the opportunity to own end-to-end mechanical design for liquid-cooled server infrastructure, optimize thermal performance through digital-twin simulation, and shape the future of hyperscale data center cooling solutions.

Key Responsibilities :

• Own complete mechanical design lifecycle for 3D assemblies including rack structures, cooling manifolds, fluid connectors, and electrical component integration (power shelves, busbars, BBUs)
• Architect and validate high-performance liquid-cooling systems (CDMs) optimizing for flow efficiency, thermal performance, and material compatibility
• Develop comprehensive digital-twin models and perform CFD analysis for thermal management
• Conduct FEA to ensure structural integrity under operational loads
• Collaborate with hardware, electrical, and facilities teams for fully integrated system design
• Produce detailed design documentation including 3D models, 2D fabrication drawings, BOMs, and simulation reports
• Lead design review processes ensuring adherence to industry standards (OCP, ASHRAE, EIA)
• Drive rapid prototyping using 3D printing and fabrication methods for design validation
• Lead technical evaluation and vendor selection for critical components
• Champion continuous improvement of design templates and simulation workflows

Requirements :
