Mechanical Engineer -Thermal

Vertiv•Delaware, OH

About The Position

The Mechanical Engineer – Thermal works within Vertiv’s global new product development team to design critical infrastructure products for next-generation data centers. The role focuses on thermal and mechanical system design for new products, platforms, and customer-driven solutions, including liquid cooling, HVAC integration, heat rejection, airflow management, and emerging cooling technologies. The engineer owns mechanical and thermal design activities from concept through release. Work includes system architecture, equipment and component selection, thermal and fluid calculations, BIM/3D modeling, coordination of CFD and fluid-network modeling, bill of materials generation, prototype support, design verification, and production readiness. The role requires balancing performance, cost, manufacturability, reliability, serviceability, and schedule while collaborating across engineering, manufacturing, suppliers, product management, and customer-facing teams. The position may require travel of up to 15–25% to support supplier reviews, prototype builds, factory integration, customer projects, and R&D activities. Vertiv will employ only candidates legally authorized to work in the United States; sponsorship is not provided.

Requirements

Bachelor’s degree in Mechanical Engineering or a related engineering discipline.
3–5 years of relevant engineering experience in product development, data center infrastructure, HVAC systems, thermal systems, modular infrastructure, or mission-critical facilities.
Strong understanding of thermodynamics, heat transfer, fluid mechanics, refrigeration cycles, airflow management, and mechanical component selection.
Experience developing engineering drawings, 3D models, mechanical assemblies, schematics, specifications, bills of material, and release documentation.
Proficiency with BIM/CAD tools such as Revit, Inventor, AutoCAD, Creo, SolidWorks, or similar platforms.
Experience working with suppliers, manufacturing teams, quality teams, and cross-functional engineering groups to launch new products or complex engineered systems.
Strong communication, problem-solving, innovation, curiosity, and technical decision-making skills.
Ability to work independently, manage multiple priorities, and make sound engineering tradeoffs in a fast-paced product development environment.

Nice To Haves

Advanced degree in an engineering discipline; a master’s or PhD in thermodynamics, heat transfer, fluid mechanics, or a related discipline is preferred.
Experience with modular data center products, prefabricated infrastructure, liquid cooling, CDUs, chillers, CRAHs, dry coolers, pumps, heat exchangers, piping, or heat rejection systems.
Experience with CFD or fluid-network modeling tools such as Cadence Reality DC, Ansys, Flownex, GT-Suite, Modelica, or similar platforms.
Familiarity with ASHRAE guidance, energy codes, and design practices for critical infrastructure environments.
Experience supporting prototype builds, laboratory testing, factory acceptance testing, design validation, and production launch.
Demonstrated ability to innovate within real-world constraints and communicate technical recommendations to engineering leaders, customers, and business stakeholders.

Responsibilities

Develop conceptual, detailed, and production-ready thermal designs for new data center infrastructure products and platforms.
Translate customer requirements, product roadmaps, and business needs into engineering requirements, system architectures, and practical design solutions.
Design and integrate liquid cooling, HVAC, heat rejection, airflow management, and other mechanical subsystems into complete data center infrastructure solutions.
Perform thermal, fluid, airflow, energy, and component-selection calculations to guide product decisions and validate design performance.
Create BIM/3D models, drawings, schematics, specifications, bills of material, and release documentation for prototypes, production release, and customer-facing deliverables.
Drive prototype learning, coordinate CFD and fluid-network modeling, support laboratory testing and design verification, and address corrective actions.
Collaborate with electrical, controls, structural, manufacturing, procurement, quality, service, product management, and sales teams to deliver integrated and scalable product solutions.
Support supplier selection, component sourcing, technical bid evaluation, and manufacturability reviews for critical mechanical and thermal components.
Provide production and field support during prototype builds, factory integration, testing, customer projects, and R&D activities.
Lead and participate in design reviews, technical tradeoff discussions, and stakeholder presentations.
Research emerging data center cooling technologies, construction methods, and infrastructure architectures to influence future product direction.
