Principal Rack Mechanical Engineer (Rack Integration ...

This position supports hybrid work schedule depending on organization needs. How will you make an impact?We are seeking a highly skilled, technically proficient and detail-oriented Principal Rack Mechanical Engineer within the Intelligent Infrastructure Segment to lead the architecture, design, integration, and delivery of advanced air and liquid cooled server rack solutions for large-scale deployments. This role is critical in translating hyperscale data center requirements into robust, scalable, and manufacturable mechanical systems for next-gen AI/ML (GPU/CPU), cloud infrastructure, and network deployments. This person will oversee end to end rack development - from scoping and integration through validation and deployment - while driving cross functional collaboration, technical innovation, and continuous improvement across enterprise and hyperscale datacenter programs.What will you do?Create technical documentation, including L11 rack assembly instructions, 2D mechanical drawings, SOPs, and customer facing specifications.Design and validate rack-level mechanical architectures (EIA 19" and ORV3), including airflow paths, liquid cooling integration/mounting (cold-plates, manifolds, hoses, QDs), structural load considerations, fiber/network/power cable routing, and space optimization.Assemble, fit check, and mechanically integrate complex rack systems, including liquid loop components, quick disconnects, manifolds, and power distribution units (PDUs).Lead the specification and validation of rack level power architecture, including PDU selection, detailed power budget and load balancing calculations (wye vs. delta, 3ph vs. 1ph), and compatibility with global power plug and connector standards.Participate in customer engagements and site visits to understand deployment constraints (white-glove services) and gather feedback for design improvements.Understanding of rack installation constraints, maintenance access, and serviceability in rack mechanical infrastructure.Create detailed computer aided design (CAD) models and fabrication drawings, including weldments, sheet metal, and machined parts for customized rack solutions.Develop and maintain design documentation including bill of materials (BOMs), cable BOMs, alternate sourcing strategies, test plans, and engineering change orders (ECOs).Manage relationships with mechanical component vendors, including racks, PDUs, switches, cables, and packaging solutions.Lead internal and external mechanical design reviews and contribute to cross-functional design validation efforts.Drive continuous improvement in mechanical design for manufacturability (DFM), cost reduction, and performance optimization.Conduct root cause analysis and corrective actions for mechanical failures or field issues.Collaborate with compliance and certification teams to ensure mechanical designs meet global regulatory requirements (e.g., UL, CE, ISTA, ASTM, IEC).May perform other duties and responsibilities as assigned.How will you get here?
