Internship, Embedded Software Engineer, High Voltage Systems; Fall

What To Expect

Consider before submitting an application:
This position is expected to start August or September 2026 and continue through the fall term (ending approximately December 2026) or into Winter/Spring 2027 if available and opportunities arise. We ask for a minimum of 12 weeks, full‑time (40 hours per week) and on‑site, for most internships. The internship program is for students who are actively enrolled in an academic program.

Recent graduates seeking employment after graduation and not returning to school should apply for full‑time positions, not 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 a 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.

As an Embedded Software Engineering Intern on the High Voltage System (HVS) Team, you will help deliver the high‑quality software that enables our vehicles to be the best in the world. The team develops all the software required to make our products (past, present, and future) the best by writing low‑level firmware drivers, implementing software algorithms, and designing and building validation/test infrastructure.

The HVS team places an especially large emphasis on ensuring we deliver a product that is safe, reliable, has high‑quality user‑facing indicators (range, SOC, power, etc.), and optimizes our overall customer experience.
