Internship, Thermal Design Engineer, Energy Engineering (Fall 2025)

Consider before submitting an application:

This position is expected to start August/September 2025 and continue through the entire Fall term (i.e. through approx December 2025) or into Winter/Spring 2026 if available. We ask for a minimum of 12 weeks, full-time and on-site, for most internships.

International Students: If your work authorization is through CPT, please consult your school on your ability to work 40 hours per week before applying. You must be able to work 40 hours per week on-site. 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 teams success.

The Tesla Energy thermal design team is a close-knit group of hands-on mechanical engineers bringing 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. The role requires collaboration with the architecture team, adjacent design teams, manufacturing, and service, and requires the ability to apply engineering fundamentals to design thermal assemblies that are at the core of Teslas success. Our team is composed of individuals who are fast-moving, self-motivated, resilient, who love to solve difficult problems, and are team players. If this sounds like you, then our team could be the right place for you.
