Job summary

CoolIT, an Ecolab company, is seeking a Thermal Mechanical Engineer to push liquid cooling technologies for AI and HPC. You will design and validate passive cold plates, manifolds, and modular assemblies, while ensuring performance, reliability, and manufacturability.

You will advance technologies from TRL 3 to TRL 5, create production-ready CAD models and drawings, perform CFD, FEA, and DFMEA, and collaborate with manufacturing, quality, and customers to drive early-stage concepts into product

Qualifications

Bachelor's degree in Mechanical Engineering or a related engineering discipline.
Experience applying heat transfer and fluid mechanics principles to thermal design, including CFD models.
Strong understanding of GD&T, tolerance analysis, mechanism design, FEA, DFM, and DFMEA.
Engineering testing, validation, and root cause analysis.
Proficient in CAD and simulation tools (e.g., SolidWorks) to create production-ready models and drawings.

Responsibilities

Design and mature thermal-mechanical products and concepts relating to passive cold plates, coolant distribution manifolds, and modular cooling system assemblies, with a focus on technology advancement for performance, reliability, cost, and manufacturability.
Advance the maturation of liquid cooling technologies from approximately Technology Readiness Level (TRL) 3 through TRL 5, preparing technologies for successful adoption by product development teams.
Create and maintain detailed CAD models, engineering drawings, bills of materials, and related documentation in accordance with company standards, GD&T practices, and DFM requirements.
Conduct thermal, fluid flow, and structural analyses, and perform laboratory testing, data analysis, DFMEA, and root cause investigations to validate designs and optimize product performance.
Provide technical support for customer programs requiring technology development when solutions have not yet achieved the required readiness level.
Work on challenging engineering problems involving heat transfer, fluid dynamics, mechanical design, simulation, and product validation within tight timelines.
Serve as a technical representative at customer sites by providing hands-on engineering support, gathering customer and application requirements, identifying emerging product and technology trends, and helping transition early-stage liquid cooling technologies into customer programs.
