Job description

Are you passionate about solving complex thermal challenges that enable the next generation of AI, high-performance computing, and sustainable data center technologies? At CoolIT, an Ecolab company, you'll help develop innovative liquid cooling solutions that support some of the world's most demanding computing environments.

As a Thermal Mechanical Engineer, you will design, develop, and validate liquid cooling solutions for high-performance electronics, including passive cold plates, coolant distribution manifolds, and modular cooling system components. Working within our IT Cooling Design Engineering team, you will apply thermal, fluid, and mechanical engineering expertise to deliver products that meet performance, reliability, cost, and manufacturability objectives. In addition to leading product development from concept through production, you will work directly with customers throughout the design cycle, providing technical guidance, supporting design integration, and helping resolve engineering challenges both remotely and on-site. Reporting to the Thermal Mechanical Engineering Team Lead, you will play a key role in delivering innovative cooling technologies while strengthening customer partnerships.

What's in it For You:

• Generous paid time off, flex days, and paid company-wide shutdown during the holiday season.

What You Will Do:

• Design and develop thermal-mechanical products and components, including passive cold plates, coolant distribution manifolds, and modular cooling system assemblies, with a focus on performance, reliability, cost, and manufacturability.
• Lead product development activities from concept through production, including design studies, prototype development, design verification, risk assessment, and release to manufacturing.
• 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, structural analyses, and perform laboratory testing, data analysis, and root cause investigations to validate designs and optimize product performance.
• Collaborate closely with customers and cross-functional teams, including testing, manufacturing, quality, supply chain, and product management, to understand requirements, resolve technical challenges, and ensure successful product integration throughout the design cycle.
• Serve as a technical representative at customer sites, providing hands on engineering support, participating in design reviews, gathering product and application feedback, and helping drive efficient issue resolution from development through early production.

Position Details:

• Travel: Required travel to customer sites within the Bay area .
• Occasional travel to headquarter in Calgary AB Canada for training
• Minimal International travel may be required based on business needs.
• Candidate must reside in: Commutable distance of the Bay Area, CA
• Work location: Remote when not at customers sites
• Work week and shift: Full-time, standard business hours

Minimum Qualifications:

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• Proven experience designing mechanical components and assemblies for mass production using multiple manufacturing processes.
• Strong understanding of core mechanical engineering principles, including:
• Geometric Dimensioning & Tolerancing (GD&T)
• Tolerance stack-up and statistical tolerance analysis
• Mechanism design and analysis
• Finite Element Analysis (FEA)
• Design for Manufacturing (DFM)
• Design Failure Mode and Effects Analysis (DFMEA)
• Product Lifecycle Management (PLM)
• Engineering testing, validation, and root cause analysis
• Proficient in CAD and simulation tools (e.g., SolidWorks) to create production-ready models and drawings, perform analyses, and optimize design performance.
• Strong written and verbal communication skills, with proven experience working directly with customers to gather requirements, communicating technical concepts, and resolving engineering challenges.

Preferred Qualifications:

• Minimum 5 years of experience in thermal-mechanical product development.
• Strong understanding of fluid mechanics, heat transfer, and cooling system design.
• Experience designing products for high-volume manufacturing environments.
• Master’s degree in mechanical engineering, Thermal Mechanical Engineering specializing in Fluid Dynamics, or a related field.
