Description

We are seeking a Principal Mechanical Engineer to lead the hardware definition of our next-generation AI infrastructure. This is a high-impact leadership role where you will serve as the primary technical authority for the physical architecture of advanced server platforms. You will bridge the critical gap between ultra-high-power silicon packaging, liquid-cooled node design, and massive-scale Rack deployments. Key Responsibilities Blade & Chassis Design: Lead the end-to-end mechanical definition of server blades, high-density chassis, and rack-level enclosures. Structural Hardware: Architect the integration of sliding rails, blind-mate connectors, precision standoffs, and high-load Extraction Handles. Power & Interconnects: Define mechanical paths for ultra-high-density power delivery (Busbars) and complex cable management. Cold Plate & Fluid Management: Review liquid cooling management by providing mechanical integration feedback on manifold distribution and QD/leak-mitigation system compatibility. Thermal Simulation & Strategy: Contribute mechanical design inputs to balance hybrid air/liquid cooling solutions. Simulation: Drive thermal strategy for 1kW+ nodes using CFD to balance hybrid air/liquid cooling. HVM Mastery: Optimize designs for high-volume manufacturing using Precision Milling, Die Casting, and Complex Sheet Metal fabrication. Environmental Ruggedization: Ensure system integrity against Transportation Shock & Vibration and extreme Thermal/Humidity cycling. Total Lifecycle Design: Implement Design for Cost (DfC) and Easy Assembly (DFA) to ensure seamless serviceability and global deployment. Requirements Required Qualifications Education: B.S. or M.S. in Mechanical Engineering. Experience: 12+ years in high-performance compute (HPC), AI hardware, or datacenter systems. Architectural Pedigree: A proven track record of owning at least one full product lifecycle—from blank-page concept through High-Volume Manufacturing (HVM). Manufacturing Mastery: Expert-level understanding of metal fabrication (Milling, Casting, Sheet Metal) and how these processes impact thermal performance and structural integrity. Liquid Cooling Expertise: Technical knowledge of fluid dynamics, wetted material compatibility, and the mechanical nuances of "Drip-Free" connector integration. Simulation Proficiency: Expert user of FEA tools for structural and vibration analysis. Influence: Ability to drive technical alignment across silicon, power, and optical engineering teams. Preferred Qualifications Direct experience with AI/GPU-based architectures and ultra-high-density power delivery Deep familiarity with Open Compute Project (OCP) or ORV3 standards. Experience with blind-mate liquid and power interfaces.

Responsibilities

The Principal Mechanical Engineer will lead the hardware definition and physical architecture of advanced AI infrastructure, including server blades, chassis, and rack-level enclosures. They will oversee the integration of power delivery, liquid cooling systems, and structural components while ensuring high-volume manufacturing readiness.
