Staff Engineer, Thermal Design

Celestica International LP•Austin, TX

1d•$128,000 - $200,000

About The Position

Join Celestica’s Hardware Product Development team to create high-end electronics cooling solutions for systems such as AI servers, switches, and accelerators. The role owns thermal design from modeling and design through testing, revisions, and transfer to manufacturing. It involves thermal simulations and analysis across scales from chips to facilities, development of cooling solutions, and hands-on validation in a collaborative, multidisciplinary environment.

Requirements

At least 5 years of relevant industry experience.
Proven track record in high-performance server thermal management, advanced liquid-cooling design, and hyperscale data center infrastructure.
Bachelor’s degree in Mechanical Engineering, or 4 years of relevant experience in lieu of a bachelor’s degree.
Relevant coursework in heat transfer and fluid mechanics.
Good familiarity with 3D software applications.

Nice To Haves

Master’s or Ph.D. in Mechanical Engineering, specializing in Thermal-Fluid Sciences.

Responsibilities

Own thermal design for electronic products, from thermal modeling, design, and testing through design revision and transfer to manufacturing.
Conduct thermal simulations, postprocessing, and analysis from chip to facilities level to verify thermal feasibility, assess risk, and inform designs.
Maintain awareness of available heat-transfer hardware, its operation and performance, cost, and potential incorporation into products.
Develop and implement ways to enhance and extend the operation of heat-transfer hardware.
Consider thermal aspects of chip packaging technologies.
Apply fluid-flow geometries and technologies to cool high-heat-flux chips.
Determine and account for contact resistance and the use of Thermal Interface Materials.
Use air cooling when possible and liquid cooling when necessary to achieve 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 work to meet required performance and schedules supporting product development.
Account for real-world manufacturing methods and costs, reliability, incoming-part variability, and specification tolerances.
Perform hands-on lab tests from component to rack and facility level to validate designs and models.
Document thermal test plans and 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 and use statistical methods as needed to maximize data utilization and test usefulness.
Work with multidisciplinary groups to define system requirements and design products.
Work with cross-functional teams to identify root causes of system performance.
