Internship, Embedded Software Engineer, High Voltage Systems (Winter/Spring 2027)

Tesla is seeking an Embedded Software Engineering Intern to support its High Voltage System team. The role involves developing low-level firmware, real-time software algorithms, and scalable simulation and validation infrastructure for vehicle high-voltage systems, including battery management, power conversion, and charging.

What you'll do:

• Develop low-level FW drivers to support new and existing microcontrollers
• Design and implement real-time software algorithms for features across the high voltage system including the battery management system, power conversion system, the charge port, and more Various features include state of charge (SOC) estimation, power estimation, AC-DC conversion, DC-DC conversion, and supporting new charging protocols among many other features
• Work with various cross-functional teams to develop requirements and test plans for new software features, diagnostics, algorithms, etc
• Develop scalable software-in-the-loop (SIL) and hardware-in-the-loop (HIL) infrastructure for rapid prototyping, simulation, and validation
• Develop and enhance existing battery and hardware models to ensure simulations are representative of the real-world
• Design simulation frameworks that are flexible to being integrated both with other Tesla subcomponents as well as behavioral models for those subcomponents

What they're looking for:

• You must be able to work 40 hours per week onsite
• Currently working towards a degree in Electrical Engineering, Computer Engineering, Software Engineering, Mechatronics, or a related field of study with a graduation date between May 2027 – May 2028
