About the Job

Requirements

  • Currently pursuing a degree in Mechanical Engineering or a thermals-related field, with a graduation date between May 2027 and December 2027.
  • Have a strong understanding of heat transfer, thermodynamics, and fluid dynamics fundamentals.
  • Have experience with computational fluid dynamics (CFD) and developing numerical models of thermal or fluid systems at any level.
  • Have hands-on experience with mechanical or thermal testing and data analysis.
  • Be able to work 40 hours per week on-site; international students relying on CPT should confirm with their school that they may work 40 hours per week.
  • Be actively enrolled in an academic program; recent graduates who will not return to school should apply for full-time positions.

Responsibilities

  • Model heat transfer and fluid flow for SI hardware cooling using computational fluid dynamics.
  • Support evaluation of new cooling technologies, including thermal interface materials, heat spreaders, and cold plates.
  • Perform thermal and mechanical first-principles analysis and simulations.
  • Test and validate electronic systems across all low-voltage electronics.
  • Support manufacturing lines and test engineers in identifying issues, resolving problems, and developing production solutions.
  • Create documentation and presentations to communicate concepts, designs, and findings.
  • Design and validate air and liquid cooling solutions for SI hardware, collaborating across the full system design, including chip packages, printed circuit boards, compute and network trays, racks, and infrastructure.
  • Explore advanced cooling technologies to increase compute density and system efficiency.

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.
