About the Data Center Infrastructure (DCI) Team:

The DCI team consists of technical subject matter experts who specialize in end-to-end large scale physical infrastructure that powers and enables modern data centers. This includes power distribution systems such as transformers, substations, generators, switch gear, switch panels, busways, ATS units, EDPM, BMS systems, and control panels, as well as cooling solutions ranging from traditional evaporative and indirect cooling systems to emerging liquid cooling technologies including chillers, heat exchangers, CDUs, pumps, and secondary fluid networks.

The team also addresses the mechanical structures that house these systems - hot aisle containment, steel enclosures, blanking panels, cable trays, and fiber and networking infrastructure.

The DCI team operates as a cross-industry center of excellence, partnering primarily with various hyperscaler cloud providers across the industry. Team members function as deeply technical subject matter experts who engage directly with customers and supply chain partners to assess requirements, identify challenges, and design infrastructure solutions end-to-end. The ideal contributor brings engineering-level expertise in either power or cooling disciplines, a working knowledge of the full infrastructure dependency chain, and the ability to translate that expertise into clear recommendations and collaborative problem-solving with both technical and business stakeholders.

How will you make an impact?

The Mechanical Integration Engineer is responsible for defining factory level mechanical and thermal solutions that enable the setup, expansion, and optimization of greenfield and brownfield Jabil owned manufacturing facilities in addition to product support. This role leads early phase factory design by scoping, specifying, and integrating mechanical and cooling systems, mimicking data center infrastructure functionality where required, and translating product and process requirements into scalable factory architectures that support efficient facility setup, equipment deployment and long-term manufacturing readiness.

The position also includes leading test process implementation and equipment selection to maintain the highest standards of operational excellence and reliability.

What will you do?

* Lead the design of factory level mechanical and cooling architectures, leveraging hyperscale data center design principles to define scalable, resilient infrastructure for Jabil manufacturing facilities

* Design and integrate air cooled and water cooled chiller plants, dry coolers, heat rejection systems, and associated hydronic distribution networks.

* Define cooling plant performance requirements including capacity, redundancy (N, N+1, 2N), efficiency, availability, and scalability.

* Partner with electrical, controls, and operations teams to ensure cooling systems meet availability, resilience, and operational excellence targets.

* Act as a subject matter expert for single phase and two phase liquid cooling technologies used in hyperscale data centers.

* Architect and integrate rack level, row level, and facility based liquid cooling systems, including CDUs, manifolds, and heat exchangers.

* Define operational requirements for LC infrastructure, including pressure ratings, temperature envelopes, flow uniformity, materials compatibility, and long term durability.

* Ensure seamless thermal and mechanical integration between facility cooling plants and high density IT liquid cooling loops.

* Review and approve mechanical designs, CAD models, and technical data packages for compliance with system level requirements.

* Own component selection for piping, valves, fittings, pumps, heat exchangers, and cooling equipment based on fluid type, pressure, temperature, corrosion resistance, and lifecycle cost.

* Develop and release Bills of Materials (BOMs) and manufacturing documentation for production and deployment.

* Ensure designs comply with applicable codes, standards, and best practices (ASME, ISO, applicable building and pressure vessel codes).

* Perform or oversee thermal, hydraulic, and mechanical analyses, including flow modeling, pressure drop, and stress evaluation.

* Define and lead system…
