Firmware & Validation Intern – Power Electronics PIL/SIL (m/f/d)

| Job Category | Engineering & Information Technology | | Location | Freiburg im Breisgau | | Req. ID | 274646 | | Job Type | Intern/Apprentice |

What to Expect

Disclaimer: We offer full-time (40h/week) internships for a minimum of 6 months. Please consider before submitting an application.

At Tesla Engineering Germany in Freiburg, we develop cutting-edge power electronics and firmware for energy storage and vehicle charging systems. Join our team to work at the intersection of control theory, embedded firmware, and hardware-in-the-loop validation.

This is a unique opportunity to contribute to the development of a modern Processor-in-the-Loop (PIL) and Software-in-the-Loop (SIL) validation infrastructure for power electronics controls. You will work closely with the Power Electronics Control firmware team and collaborate with cross-functional teams across Tesla to bring robust, scalable validation tooling to production-grade firmware.

What You’ll Do

• 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

What You’ll Bring

• At least 6 months of availability for a mandatory or voluntary internship

• Bachelor's or higher degree in Electrical Engineering, Computer Science, Mechatronics, or a related field

• 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

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

• 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

• Strong analytical mindset and ability to work independently in a cross-functional, international team

• Tesla is an Equal Opportunity employer. All qualified applicants will receive consideration for employment without regard to any factor, including veteran status and disability status, protected by applicable federal, state or local laws.

• Tesla is also committed to working with and providing reasonable accommodations to individuals with disabilities. Please let your recruiter know if you need an accommodation at any point during the interview process.
