About Etched Etched is building the world’s first AI inference system purpose-built for transformers - delivering over 10x higher performance and dramatically lower cost and latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.
Job Summary We are seeking a highly experienced Senior Thermal Engineer, Liquid Cooling Systems to join our team and lead our efforts in optimizing thermal management for high-performance systems. As a Senior Thermal Engineer, Liquid Cooling Systems at Etched, you will play a crucial role in developing and implementing advanced thermal management solutions for our high-performance data center products. Your expertise in water cooling, thermal simulations, and cooling system design will be essential in ensuring optimal thermal performance and reliability. You will work with various water cooling components, including internal manifolds, quick disconnects, CDU (Coolant Distribution Units), heat exchangers, and advanced thermal interface materials.
Key Responsibilities
You maybe a good fit if you have
We encourage you to apply even if you do not believe you meet every single qualification.
Benefits
Medical, dental, and vision packages with generous premium coverage
$500 per month credit for waiving medical benefits
Housing subsidy of $2k per month for those living within walking distance of the office
Relocation support for those moving to San Jose (Santana Row)
Various wellness benefits covering fitness, mental health, and more
Daily lunch + dinner in our office
How We’re Different Etched believes in the Bitter Lesson. We think most of the progress in the AI field has come from using more FLOPs to train and run models, and the best way to get more FLOPs is to build model-specific hardware. Larger and larger training runs encourage companies to consolidate around fewer model architectures, which creates a market for single-model ASICs.
We are a fully in-person team in San Jose (Santana Row), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
Compensation Range: $200K - $250K
