## Description

As a member of the Cell Data Team, you will write code toextract the data from our battery cyclers, transform the current voltage time data into meaningful battery measurements, and load that data in ourvarious 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
