How will you make an impact?We are seeking a highly skilled, technically proficient and detail-oriented
Principal Rack Integration Engineer within the
Intelligent Infrastructure Segment to lead the architecture, integration, and delivery of advanced air and liquid-cooled server and network switch solutions for large-scale deployments. This role is critical in translating hyperscale data center requirements into robust, scalable, and manufacturable 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 initial architecture review of customer requirements, through validation and deployment. This person will also drive cross-functional collaboration, technical innovation, and continuous improvement across multiple datacenter programs.
What will you do?- Lead complex, multi-disciplinary hardware programs - coordinating mechanical, thermal, electrical, supply chain, and manufacturing teams - while aligning requirements, driving schedules, and ensuring successful delivery of integrated rack, network, and cooling solutions.
- Develop and maintain bill of materials (BOMs), cable BOMs, alternate sourcing strategies, test plans, and engineering change orders (ECOs).
- Assemble, fit-check, and mechanically integrate complex rack systems, including liquid loop components, quick-disconnects, manifolds, and power distribution.
- Manage relationships with mechanical L11 component vendors, including rack, PDUs, switches, cables, and packaging solutions.
- Lead L11 rack shock and vibration qualification efforts, partnering with third-party test laboratories to develop test plans, obtain quotations, align on pass/fail criteria, and ensure test methodologies are appropriately benchmarked against applicable ASTM, ISTA, and other relevant industry standards.
- Create technical documentation, including rack assembly instructions, 2D mechanical drawings, test reports, SOPs, and customer-facing specifications.
- Participate in customer engagements and site visits to understand deployment constraints (white-glove services) and gather feedback for design improvements.
- Lead the specification and validation of 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.
- Understanding of rack installation constraints, maintenance access, and serviceability in rack mechanical infrastructure.
- 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.
How will you get here? Education: - Bachelor's degree in Mechanical Engineering or related background plus hands-on experience
Experience: - Minimum of 7+ years' experience in mechanical systems integration/rack integration. This could include high-density server, network switches, and/or rack design and integration, including end-to-end delivery for large-scale deployments worldwide
- Excellent communication and cross-functional collaboration skills - a must
- Strong understanding of mechanical systems, integration strategies, and program management
Knowledge, Skills, Abilities: - Excellent interpersonal and communication skills
- Capable of assessing projects, articulating risks, and developing project milestones
- 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
- 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:- Review 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.
- Hands-on experience with prototype fabrication and testing; experience working with global suppliers and contract manufacturers (CM) a plus.
- Proficiency in CAD tools (e.g., SolidWorks, Creo/Pro-E, Inventor) and FEA software (e.g., ANSYS, Abaqus).
- High level knowledge of fluid dynamics, pressure drop calculations, and pipe sizing for glycol-based systems.
