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 for high-power processors.
• Conduct detailed thermal simulations to predict and analyze thermal performance.
• Evaluate and select thermal interface materials (TIMs) and optimize performance.
• Explore advanced thermal cooling concepts such as phase change cooling.
• Oversee testing and validation of thermal management systems to ensure reliability and efficiency.
• Create and maintain comprehensive documentation for designs, simulations, and testing reports.
• Collaborate with cross-functional teams including mechanical and electrical engineers.

Requirements

• Bachelor’s degree in Mechanical Engineering, Thermal Engineering, or a related field.
