Principal Rack Mechanical Engineer (Rack Integration Solutions)

Jabil•Austin, TX

About The Position

At Jabil we strive to make ANYTHING POSSIBLE and EVERYTHING BETTER. We are proud to be a trusted partner for the world's top brands, offering comprehensive engineering, manufacturing, and supply chain solutions. With over 50 years of experience across industries and a vast network of over 100 sites worldwide, Jabil combines global reach with local expertise to deliver both scalable and customized solutions. Our commitment extends beyond business success as we strive to build sustainable processes that minimize environmental impact and foster vibrant and diverse communities around the globe. 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?

Requirements

Bachelor’s degree in Mechanical Engineering, Systems Engineering, or related field is required
Minimum of 5+ years experience in mechanical systems integration. This could include high-density server rack design and integration, end-to-end delivery for large-scale deployments, and customer facing support for top AI/ML companies
Proficiency in CAD tools (e.g., SolidWorks, Creo/Pro-E, Inventor)
Excellent communication and cross-functional collaboration skills – a must
Strong understanding of mechanical systems, integration strategies, and program management
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%

Nice To Haves

Master’s Degree in Mechanical Engineering, Systems Engineering, or related field is preferred.
Experience designing mechanical systems for data centers, telecom, or industrial power/cooling products (UPS, generators, CDUs).
Active Professional Engineer (PE) license preferred but not a requirement.
Hands-on experience with prototype fabrication and testing; experience working with global suppliers and contract manufacturers (CM) a plus.
Knowledge of fluid dynamics, pressure drop calculations, and pipe sizing for glycol-based systems.
Perform structural analysis using FEA tools (e.g. ANSYS, other) to validate mechanical rack and packaging integrity under static, dynamic, seismic, and thermal loads.

Responsibilities

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.

Benefits

Annual bonus opportunity
Medical, dental, and vision insurance plans
Paid time off (PTO) accruing at a rate of 3.07 hours during your first year of employment
4 weeks of paid parental leave
11 company-paid holidays (9 fixed holidays and 2 optional floating holidays), subject to change yearly
401(k) retirement plan
Employee stock purchase plan
