Mechanical Engineer - Thermal

The Opportunity

Data centers are evolving rapidly as AI, high-density compute, and sustainability demands push thermal infrastructure beyond traditional designs. In this role, you will work on the products and designs that help customers deploy mission-critical infrastructure at megawatt scale with speed and efficiency. You will collaborate with manufacturing, product management, suppliers, and customer-facing teams to turn early concepts into practical product solutions

• →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, CFD and fluid-network modeling coordination, laboratory testing, design verification, and 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.

• Bachelor’s degree in Mechanical Engineering or a related engineering discipline; advanced degree preferred.
• 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, BOMs, 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.

• Travel up to 15–25% may be required to support supplier reviews, prototype builds, factory integration, customer project support, and R&D activities.

• 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.
• Masters or PhD with thermodynamic, heat transfer, fluid mechanics, or related discipline.
• 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.

This role is well suited for an engineer who enjoys solving open-ended technical problems, learning emerging cooling technologies, working hands-on with prototypes, and translating analysis into products that can be manufactured and deployed at speed and scale for mission-critical customers.
