Senior Thermal Engineer, Liquid Cooling Systems

About the Company

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference.

Responsibilities

• Lead the design and optimization of thermal management systems for high-performance data center products, focusing on water cooling solutions.
• Develop and implement water cooling solutions including internal manifolds, quick disconnects, CDUs, and heat exchangers.
• Design and manage direct-to-processor water cooling systems to dissipate heat and maintain optimal temperatures.
• Conduct detailed thermal simulations to predict and analyze thermal performance.
• Evaluate and select thermal interface materials (TIMs) for various heat sinks and cooling solutions.
• Explore and implement advanced thermal cooling concepts such as phase change cooling.
• Oversee testing and validation of thermal management systems to ensure performance and reliability standards.
• Create and maintain comprehensive documentation for thermal management designs and simulation results.
• Work closely with cross-functional teams including mechanical and electrical engineers.

Requirements

• Bachelor’s degree in Mechanical Engineering, Thermal Engineering, or a related field.
• Minimum of 10 years of experience in thermal engineering.
• Strong focus on water cooling systems and advanced thermal management solutions.
• Proven expertise in designing direct-to-processor cooling systems and thermal simulations.
• Extensive experience with internal manifolds, quick disconnects, CDUs, and heat exchangers.
• Proficiency in thermal simulation tools and techniques.
• Knowledge of thermal interface materials (TIMs) and heat sink designs.
• Experience with advanced thermal cooling concepts and technologies.
