Staff Thermal Engineer, AI Server Cooling

Celestica; Austin (TX); On-site; USD 128,000 - 200,000; Full time

Job summary

Celestica in Austin, TX is seeking a Staff Engineer, Hardware Design to own thermal design for electronic products, running thermal modeling, testing, and design iterations from concept to production.

You will conduct simulations from chip to facility, evaluate heat transfer hardware, and collaborate with hardware, software and thermal architects to deliver best-in-class cooling solutions for AI servers and network gear.

Responsibilities

• Complete ownership of thermal design for various electronic products from thermal modeling, design, test, and design revision, until transfer to manufacturing.
• Conduct thermal simulations, postprocessing, and analysis ranging from chip to facilities level to verify thermal feasibility, risk, and to inform your designs.
• Maintain awareness of heat transfer hardware available from all sources, including how it operates and performs, its cost, and how it can be incorporated into our products.
• Conceive and implement ways to enhance and extend operation of heat transfer hardware.
• Consider the thermal aspects of chip packaging technologies.
• Apply best-in-class fluid flow geometry and technology to cool high heat flux chips.
• Determine and consider the effects of contact resistance and the use of Thermal Interface Materials.
• Apply air cooling when possible and liquid cooling when necessary to achieve full performance and reliability at the lowest cost.
• Size liquid cold plates, heat sinks, heat pipes, air movers, air filters, air ducting, and perforated plates.
• Plan your work to achieve full required performance, and stay on schedule to support overall product development.
• Reference real world limitations to inform your work, such as manufacturing methods and cost, reliability, variability of incoming parts, and tolerances on all specifications.
• Perform hands‑on lab tests of equipment from component to rack and facility level for design and model validation. Document thermal test plans, devise and build test stands, including technical support, cooling liquid supply, power delivery, metrology and instrumentation, compute workload, experiment control, and data recording.
• Analyze test data to draw inferences about the equipment tested. Apply statistical methods as required to maximize utilization of data and test usefulness.
• Work with multi‑disciplinary groups to define system requirements and design products.
• Work with cross‑functional teams to identify root causes of system performance.

Education

Master’s degree in Mechanical Engineering (preferred concentration in heat transfer and fluid mechanics)
