Embedded Firmware Engineer, Battery Management Systems

As an Embedded Software Engineer on the Battery Management System (BMS) team, you will have the opportunity to accelerate the delivery of quality Tesla products to consumer markets. You will be responsible for architecting, designing and implementing firmware validation procedures, equipment and automation regarding high voltage systems. Your effort to create and spin up various automated validation infrastructures will have a direct impact on the reliability and robustness of the Tesla products as well as the customer experience.  

This team is extremely focused on the quality of users’ indicators (i.e. range, State-of-Charge, power, etc.) which directly plays into the overall experience and the safety of the system as a whole. The team strives to create robust, efficient firmware and your responsibility is to ensure the code quality is extremely high. You will work within the development and integration teams to create innovative automated test systems and implement tests on these platforms. These systems explore and validate the performance capabilities of our hardware and firmware. You will also play an important role in our future technologies' roadmap, including firmware support for new products, packs, cells, etc. 

• Work with various cross-functional teams to develop requirements for new BMS features, diagnostics, algorithms, etc. 
• Design, implement and test cutting-edge algorithms for run-time BMS logic to derive State-of-Charge, State-of-Health, State-of-Power and State-of-Energy computations 
• Develop Software-in-the-Loop infrastructure in an object-oriented fashion, making high degree of re-use of existing objects and objects that are highly reusable 
• Develop and enhance existing battery models to ensure Real vs. Simulation accuracy 
• Design rapid test iteration framework for developers to use for quick, at-desk spot checks
