About the Job

Requirements

A degree in Thermal or Mechanical Engineering, or equivalent experience demonstrating exceptional ability in thermal management.
At least 2 years of industrial experience with evidence of exceptional performance.
Strong understanding of fluid mechanics, heat transfer, and thermodynamics fundamentals.
Proficiency in numerical simulation of heat transfer and fluid flow.
Experience with liquid and air cooling of high-power GPUs or ASICs in data centers, system flow balancing, and thermal control.
Knowledge of semiconductor packaging and package-level thermal/mechanical interactions.

Responsibilities

Design passive and active cooling solutions for high-power SI electronics in compute trays.
Provide thermal inputs to the layout and design of compute tray electronics and air/coolant delivery.
Drive thermal-system component selection from chip level (TIM, heat spreader, heatsink/cold plate) through tray level (fans, hoses, manifolds, quick disconnects) to system level (CDU, pump, filter, sensors).
Design and optimize cooling solutions for performance, cost, reliability, and risk.
Balance flow in complex rack- and compute-tray-level flow networks by developing analytical and computational models of hydraulic and thermal systems.
Define thermal policy and control algorithms, and characterize system response at different scales.
Contribute to module- and system-level validation and reliability testing, including test planning, setup, debugging, and data analysis.

Job Description

<div class="MSWordContent"><p>Tesla SI Hardware team is revolutionizing artificial intelligence and looking for a highly motivated Thermal Design Engineer to cool the next generation of high-density SI data centers powered by Dojo – our custom supercomputer. We are looking for candidates of all experience levels for this opening. The role involves design and validation of air and liquid cooling solutions for SI hardware and cross functional collaboration on the full system design including chip package, PCBs, compute/network trays, rack and infrastructure. We will explore advanced cooling technologies to push the limits of compute density and system efficiency. A deep understanding of the fundamentals of fluid flow and heat transfer and ability to breakdown complex engineering problems into simple pieces that can be tackled by fundamentals is a must. Creative thinking, ability to solve complex and challenging problems, and ability to work independently are of paramount importance. This position involves working in a dynamic and fast-paced environment with tight timing and dynamic constraints.</div>

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
