Sr. Software Engineer, ETL, Cell Engineering

The Tesla Battery Cell Data Team owns the database pipeline and databases that store battery test data. We build web applications to view that data, start battery tests, and plan groups of tests. Our applications support hundreds of global users; our pipeline supports test labs across the world and dozens of different data streams. We are comprised of data and software engineers. We stay close to our end user and engineers on our team have autonomy to define the vision for their products.

As a member of the Cell Data Team, you will write code to extract the data from our battery cyclers, transform the current voltage time data into meaningful battery measurements, and load that data in our various data storage layers. By efficiently loading the data and making it available, you will greatly enhance our ability to make informed decisions regarding new battery technologies, drive down battery costs, and accelerate the transition to sustainable energy.
