Principal Mechanical Design Engineer – Data Center Infrastructure

This is a fully remote position, open to applicants in Texas.

📋 Description

• Oversee the comprehensive mechanical design and engineering of hyperscale Data Center Infrastructure systems, which encompass liquid-cooled rack assemblies, CDUs, manifolds, enclosures, structural frames, and hydronic piping systems.

• Act as the technical expert for both single-phase and two-phase liquid cooling architectures, primary and secondary loop design, in-rack distribution, and integration within hyperscale data centers.

• Establish and verify operational performance criteria, including pressure ratings, hydrostatic limits, temperature ranges, flow rates and uniformity, thermal expansion, durability, and serviceability.

• Design, analyze, and ensure the integrity of machined components, welded fabrications, manifolds, and structural systems.

• Lead the selection and analysis of wetted materials for compatibility in liquid cooling systems.

• Create and assess CAD models and technical data packages utilizing CREO, SolidWorks, or similar design tools.

• Generate and validate technical specifications for piping systems, rack-level cooling infrastructure, and hydronic components.

• Develop and manage validation protocols, including hydrostatic pressure testing, leak detection, flow resistance analysis, and corrosion verification.

• Assess customer design proposals and technical specifications for feasibility, manufacturability, cost, and potential risks.

• Facilitate cross-functional design reviews with electrical, thermal, manufacturing, quality, and supply chain teams.

• Enhance the design and manufacturing processes of rack manifolds.

• Promote continuous improvement in manufacturing assembly techniques and tooling.

• Lead root cause analysis for intricate mechanical failures and implement corrective design enhancements.

• Provide technical guidance in vendor qualification and management.

• Identify and manage technical risks while contributing to R&D efforts that advance liquid cooling technologies.

• Incorporate modular data center design principles into the integration of liquid cooling systems.

• Design cooling systems for prefabricated and skid-mounted installations, considering transport and vibration loads, shipping limitations, and inter-module interfaces.

⛳️ Requirements

• Bachelor’s degree in Mechanical Engineering, Systems Engineering, or a related engineering field from an accredited institution.

• 8 years of experience in mechanical design and the integration of mission-critical systems.

• Proven history of successful system designs and implementations within a relevant industry.
