Thermal Engineer, Server Design

We are hiring a recent college graduate to join our team as a Thermal Engineer. The target start date for this role will be Spring 2025.

Lenovo researches, develops, and manufactures x86 processor based servers. The pace of technology change in this market is rapid, and our development engineers are constantly challenged to improve the thermal performance and efficiency of our products. Lenovo is looking for an engineer with a strong desire to innovate on thermal solutions for our server products.

Candidate will work with an engineer and conduct thermal development and testing. The testing will involve the following task:

• Evaluation of system fans from different vendors
• Measuring overall system/server air flow & impedance
• Evaluation of heatsinks from different vendors
• Running stress on components like CPUs, GPUs, DIMMs etc. and monitoring their temperature
• Review server system concepts and market requirements and enable a thermal solution that is compliant to the specifications of the critical components.
• Ensure that the printed circuit board layouts permit thermal solution placement and adequate airflow / waterflow to cool all components
• Select fans, heat sinks, and other thermal solution components which are low cost yet meet all performance requirements
• Provide mechanical and thermal review for prototyping boards
• Document and analyze simulation and test results
• Write test plans

Basic Qualifications:

• Bachelor’s Degree in Mechanical Engineering
• Currently authorized to work in the United States on a full-time basis
• Knowledge in heat transfer and fluid dynamics
• Experience conducting thermal tests to qualify the server design
• Experience using CFD (Computational Fluid Dynamics) tools to predict operating performance of the server, specifically Flotherm CFD
• Modeling and testing skills to validate a design, example measuring airflow and temperature on the air bench
• Data acquisition and ability to organize and summarize results
• Ability to work onsite in Morrisville, NC

Preferred Qualifications:

• Code skills such as Matlab, Python, or Java to automate data collection and report generation
• Knowledge of computer firmware code and algorithms that set operating points, and fault conditions
• Knowledge of CAD, material strength, power consumption, and acoustics requirements and the impact of thermal designs on them
