Job Description

Consider before submitting an application:  

This position is expected to start around August or September 2025 and continue through the Fall term (ending approximately December 2025) or continuing into Winter/Spring 2026 if available and there is an opportunity to do so. We ask for a minimum of 12 weeks, full-time and on-site, for most internships. Our 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.   

About the Team 

As an Integration Engineer Intern, you will be responsible for ensuring firmware support for new battery management features and new hardware are designed, implemented, and tested to achieve Tesla's standards for safety and customer experience. Battery Management Systems are comprised of the controllers and firmware that monitor the battery, ensure it is delivering the most power and energy possible while maximizing capacity retention over life. BMS integration engineers are responsible for the performance of algorithms that predict available power and energy, and functions that ensure optimal charging, effective thermal management and high voltage safety monitoring.

Job Responsibilities

• Work with the design and development engineers throughout the engineering organization to ensure the relevant subsystems are designed with appropriate requirements, interfaces and interactions to achieve specific vehicle functions 
• Break down new, high-level feature requests into sub-system and component level requirements, and drive the implementation, testing and release of these features against Tesla’s firmware release schedule 
• Utilize critical analysis of potential failure modes and effects to influence these requirements 
• Develop overall validation strategy for these features and work with validation teams to ensure automated test coverage is implemented for future firmware releases 
• Work cross-functionally across mechanical, electrical, system architecture, firmware development and firmware validation teams to understand new component-level hardware changes which are being developed and how to support them in firmware – both in manufacturing and for customer use – so that they can be seamlessly introduced to our vehicle platforms 
• Develop and execute firmware integration test plans on new hardware components and firmware features to rapidly retire risk from new designs and provide feedback to the development teams to accelerate our aggressive development cycles 
• Dig into data and source code to identify and debug issues at the system level and propose robust solutions 

Job Requirements

• Currently pursuing a degree in Mechatronics, Electrical, Computer Engineering, or a related field of study with a graduation date between December 2025 – December 2026
• Hands-on technical experience debugging complex systems involving networked microprocessors and software-controlled electrical or electromechanical devices 
• Experience with C or C++ required, Python is a plus 
• Thorough understanding of mechanical fundamentals - and ability to apply them to automotive concepts 
• Ability to read and understand electrical schematics 
• Experience with CAN and Ethernet networking is a plus 
• Experience with Failure Mode and Effects Analysis (FMEA) and Hazard Analysis and Risk Assessment (HARA) is a plus
