Internship, Thermal Design Engineer, Energy Engineering (Winter/Spring 2027)

What to Expect

Consider before submitting an application:

This position is expected to start January 2027 and continue through the entire Winter/Spring term (i.e through April/May 2027) or into Summer 2027 if available. We ask for a minimum of 12 weeks, full-time (40 hours/week) and on-site, for most internships.

International Students: If your work authorization is through CPT, please consult your school before applying. You must be able to work 40 hours per week. Many students will be limited to part-time during the academic year.

The Internship Recruiting Team is driven by the passion to recognize and develop emerging talent. Our year-round program places the best students in positions where they will grow technically, professionally, and personally through their experience working closely with their Manager, Mentor, and team. We are dedicated to providing an experience that allows the intern to experience life at Tesla by including them in projects that are critical to their team’s success.

The Tesla Energy thermal design team is a close-knit group of hands-on mechanical engineers bringing cutting-edge battery, charging, and renewable technologies to the world to facilitate a renewable energy ecosystem and redefine the way we all will use energy in the future.

As part of the Thermal Design Team, you will design and package the thermal systems that make Tesla Energy products world class in groundbreaking products like Megapack, Supercharger, and our new data center programs. The role requires close collaboration with the architecture team, adjacent design teams, manufacturing, and service, and requires the ability to apply strong engineering fundamentals to design innovative thermal assemblies that are at the core of Tesla's success. Our team is composed of talented individuals who are fast-moving, self-motivated, resilient, who love to solve difficult problems, and are true team players. If this sounds like you, then our team is the right place for you.

Location: Palo Alto, CA
