Sr. Software Engineer, ETL, Cell Engineering

What to Expect

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.

What You’ll Do

• Write modular Python code to manipulate high density current, voltage, time data into metrics that can be used to make battery decisions
• Work with stakeholders from across Tesla to align on needs, the minimum viable product, and future iterations of the product
• Write code to interface with battery testers
• Build data pipelines that are reliable, maintainable, and scalable
• Leverage existing APIs to fetch metadata about a battery cell. Gracefully handle service disruptions from external APIs
• Provide mentorship and code review to junior engineers
• Design metrics around the performance of the data pipeline

What You’ll Bring

• Bachelor's Degree in Computer Science, or equivalent experience
• Proficiency in Python
• Experience using Docker
• Experience with unit tests, integration tests, and end to end tests
• Experience with reading from and creating relational databases
• Experience with extracting, loading and transforming large data sets
• Experience building distributed systems
• Experience manipulating pandas or spark data frames is a plus
• Experience building public facing APIs is a plus
• Experience with electrochemistry is a plus
