Senior System Engineer - Thermal Development

About Our Team

The position is for a Senior System Engineer - Thermal in the Lenovo Infrastructure Solutions Group (ISG), based in Morrisville, North Carolina. We are seeking a Server System Engineer with server development background and thermal design and validation experiences.

This is an exciting role in Cloud Service Provider Group (CSP) that has a strong focus to be the #1 infrastructure provider for cloud datacenters that providing computing, storage, and GPU services to cloud customers. The system engineer will be an integral member of a team responsible for developing, testing innovative and complex GPU servers with liquid cooling. These organic designs provide exposure to the latest technologies from Lenovo, its development partners, and customers. At Lenovo, we pride ourselves on delivering end-to-end solutions tailored to meet even the most unique customer demands.

Our CSP solutions are conceptualized, developed, and deployed worldwide, all within our in-house expertise.

Location: This position is based in Morrisville, NC.

What You'll Do

• Develop, qualify Racks/server infrastructure in cloud data center, include compute server, storage server, GPU server.

• Design and develop thermal management solutions for server systems, including air cooling, liquid cooling, heat sinks, heat pipes, and other cooling technologies.
• Perform thermal simulations using Computational Fluid Dynamics (CFD) tools (e.g., ANSYS, Icepak, FloTHERM) to predict heat distribution, airflow, and temperature gradients in server enclosures.
• Optimize fan and blower performance for airflow, noise, and efficiency. Develop cooling strategies for high-density components such as CPUs, GPUs, memory, and power supplies.

• Work closely with mechanical, electrical, and systems engineers to ensure thermal systems meet overall product requirements and are aligned with design constraints.
• Design and implement efficient cooling systems, including heat sinks, fans, and liquid cooling to ensure optimal thermal performance under heavy loads.
• Build and test prototypes, refine designs based on test results, and troubleshoot issues related to mechanical performance, thermals, and noise.

Basic Qualifications

• Bachelor's or Master's degree in Mechanical Engineering, Thermal Engineering, or a related field with a focus on heat transfer and thermodynamics.
• 10+ years of experience in thermal design, preferably within the server, data center, or electronics industry.
• Experience with CFD tools such as ANSYS, Icepak, FloTHERM, or similar for conducting thermal simulations and optimizing airflow and heat dissipation.
• Strong knowledge of cooling technologies such as heat sinks, vapor chambers, fans, and liquid cooling solutions. Experience with high-density server environments is a plus.
• Experience in thermal testing and validation, including the use of thermal chambers, infrared thermography, and data acquisition tools for real-world performance evaluation.

Preferred Qualifications

• Experience working on thermal designs for servers, storage systems, or data center hardware.
• Experience with liquid cooling systems, vapor chambers, or immersion cooling in high-performance computing environments.
• Understanding of the thermal challenges associated with AI/ML, high-performance computing (HPC), or other advanced workloads.
• Experience with designing systems that meet energy efficiency standards and reduce overall power consumption.
• Familiarity with environmental and safety standards (e.g., UL, CE, RoHS) and energy efficiency regulations applicable to server hardware.
