About the Job

Requirements

At least 6 months of availability for a mandatory or voluntary internship.
A Bachelor's degree or higher in Electrical Engineering, Computer Science, Mechatronics, or a related field.
A solid understanding of control systems theory, including averaged modeling of resonant power converters.
Hands-on experience with embedded firmware development in C for real-time systems.
Experience with MATLAB/Simulink for modeling and simulation of power electronic systems.
Basic knowledge of SIL/PIL/HIL validation methodologies.
Familiarity with Git and working in large firmware repositories.
The ability to work independently in a cross-functional, international team.

Responsibilities

Set up and bring up FPGA-based PIL hardware at the TBF site, following existing PIL infrastructure developed for other Tesla power electronics programs.
Create and maintain a new FPGA project within the Tesla firmware repository, adapting existing PIL boilerplate (digital/analog I/O controllers, user model instantiation) for the target power electronics platform.
Develop and validate averaged models of resonant converters using generalized averaging techniques to enable faster-than-real-time SIL simulation of feedforward control algorithms.
Integrate feedforward control algorithms into the SIL test chain and validate their behavior against HIL and real hardware results.
Write and maintain embedded firmware in C targeting real-time control applications on an FPGA-based platform running Embedded Linux.
Collaborate with the validation team to define test cases and automate regression testing using Tesla's internal PIL framework.
Document hardware setup, firmware architecture, and test results on Confluence.

Desired Qualifications

Familiarity with FPGA development (VHDL/Verilog or MATLAB HDL Coder) is a strong plus.

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.
