Staff Battery Algorithms Engineer

As a member of the Battery Algorithms group, you will lead a small team within the Vehicle Software organization, whose role is to model, develop, specify, and implement control and estimation algorithms for the high voltage battery in Tesla vehicles.
These algorithms cover a wide range of customer facing attributes like state-of-energy, state-of-health, power prediction and management, fast-charging, etc. You will work highly cross-functionally, with engineers across cell development, modeling, durability and qualification, and BMS firmware, integration, and validation teams to advance the state of the art of battery estimation and management algorithms in Tesla vehicles.
Unlike anywhere else in this field, at Tesla, you will get the unique opportunity to work on a vast portfolio of cell technologies, and you will be challenged to develop, implement, and deploy robust algorithms that scale to the largest fleet of EV batteries in the world.

Responsibilities

• Own a subset of the algorithms that run on the BMS in millions of Tesla vehicles worldwide - these algorithms span cell capacity, impedance, energy, fast charging, and degradation estimation to diagnostics of sensors, cells, and battery pack components
• Identify opportunities where BMS algorithm advancements can materially impact our product standing on metrics like fast-charging, energy estimation accuracy, SOH, etc.
• Actively drive cross-functional efforts with cell modeling, cell qualification, firmware, teams to advance state-of-the-art of BMS algorithms in fast charging, energy, and health estimation
• Work with cross functional teams to take the fastest path to execute battery algorithm advancements across multiple cell programs through various parts of their life cycle
• Research, design, prototype, and prove functionality of novel battery estimation and control approaches to maximally extract performance from our cells
• Build fleet data pipelines and tools to monitor performance of your algorithms in our fleet, identify areas for improvement, and test efficacy of proposed solutions

Requirements

• Degree in Mechanical Engineering, Electrical Engineering, Materials Science, or equivalent in experience and evidence of exceptional ability
• Excellent understanding of the electrochemical physics of lithium-ion cells, and experience with modeling these physics across a range of fidelities
• Excellent ability to ground-up design, analyze, and implement, and ship battery management algorithms in real-world applications, demonstrated by strong examples
• Strong understanding of battery diagnostics and anomaly detection algorithms
• Strong evidence of ability to champion large cross-functional technical initiatives in the battery algorithms field, requiring collaboration with functions like cell modeling, cell reliability, and suppliers
• Strong evidence of ability to execute on open-ended projects in a fast-paced, resource-constrained environment
• Basic proficiency with embedded software development in C/C++
• Experience productionizing physics model-based fast-charging algorithms, preferred
