Principal Rack Mechanical Architect

Job ID: Requisition #123456 – Austin, TX – Hybrid/On-site – Full-time

About the role

We are seeking a highly skilled, technically proficient, and detail-oriented Principal Rack Mechanical Architect within the Intelligent Infrastructure Segment to lead the architecture, design, integration, and delivery of power electronics solutions for large-scale deployments. This role is critical in translating customers’ requirements into robust, scalable, and manufacturable mechanical systems for next-gen AI/ML (GPU/CPU), power, cloud infrastructure, and network deployments. You will oversee end-to-end 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.

Responsibilities

• Create technical documentation, including rack assembly instructions, 2D mechanical drawings, test reports, SOPs, and customer-facing specifications.
• Translate complex power electronics designs into manufacturable products by working closely with site manufacturing, quality, and operations teams.
• Lead training, process development, production readiness reviews, and factory enablement activities to ensure a smooth transition from engineering development to high-volume production.
• Develop and maintain design documentation including BOMs, specifications, test plans, and engineering change orders (ECOs).
• Apply a strong understanding of thermal management, magnetics design, EMI/EMC compliance, safety standards, and product reliability requirements.
• Assemble, fit-check, and mechanically integrate complex rack systems, including liquid loop components, quick-disconnects, manifolds, and power distribution.
• Specify and validate rack-level power architecture, including power distribution unit (PDU) selection, detailed power budget and load-balancing calculations (wye vs. delta, 3ph vs. 1ph), and compatibility with global power plug and connector standards.
• Account for rack installation constraints, maintenance access, and serviceability in rack mechanical infrastructure.
• Participate in customer engagements and site visits to understand deployment constraints (white-glove services) and gather feedback for design improvements.
• Create detailed computer-aided design (CAD) models and fabrication drawings, including weldments, sheet metal, and machined parts.
• Manage relationships with mechanical component vendors, including rack, PDUs, switches, cables, and packaging solutions.
• Perform advanced structural analysis using FEA tools to validate mechanical integrity under static, dynamic, seismic, and thermal loads.
• Lead 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).
• May perform other duties and responsibilities as assigned.

Requirements

• Bachelor’s degree in Mechanical Engineering, Systems Engineering, or related field (required).
• Minimum of 5+ years’ experience in mechanical systems integration, including rack, liquid cooling, power electronics, and/or mechanical design.
• Proficiency in CAD tools (e.g., SolidWorks, Creo/Pro-E, Inventor) and FEA software (e.g., ANSYS, Abaqus).
• Excellent communication and cross-functional collaboration skills.
• Strong understanding of mechanical systems, integration strategies, and program management.

Skills

• Excellent interpersonal and communication skills.
• Creative, self-motivated, accountable, and team-oriented.
• Able to work independently with minimal oversight.
• Skilled in writing reports, business correspondence, and procedural guides.
• Effective at presenting information and responding to management, clients, and public queries.
• Capable of influencing others and sharing best practices.
• Capable of assessing projects, articulating risks, and developing project milestones.
• Familiar with stage-gate processes in project lifecycle management (PLCM).
• Able to coach and mentor less experienced engineers.
• Ability to travel both domestically and internationally up to 30%.

Preferred Qualifications

• Master’s Degree in Mechanical Engineering, Systems Engineering, or related field.
• Experience supporting product commercialization and customer engagements.
• Patent, publication, or industry conference participation.
• Experience designing electrical power systems for data centers, telecom, or industrial power/cooling products.
• Provide technical leadership by establishing long-term design standards, documentation, and best practices for engineering teams.
• Liquid cooling experience within racks, servers, and/or CDUs.
• Active Professional Engineer (PE) license.
• Hands-on experience with prototype fabrication and testing; experience working with global suppliers and contract manufacturers (CM).
• Knowledge of fluid dynamics, pressure drop calculations, and pipe sizing for glycol-based systems.
