Senior Battery Data Engineer

The role

The Senior Battery Data Engineer develops the software stack for the battery characterization program. This includes data pipelines, hardware control services, and workflows connecting test data to modeling and analysis.

What you will do

• Own the data infrastructure that serves large-scale battery time-series data from battery cyclers to cloud storage
• Contribute to the software services that orchestrate testing using commercial lab battery cyclers and in-house field-level power converters
• Develop and maintain the tool layer for battery testing, such as structured protocol schemas, cycler control APIs, real-time battery test anomaly detection, and digital twin simulation
• Partner with battery test and algorithm engineers to design and build software or agentic workflows to automate inefficiencies
• Collaborate with domain experts to define agent eval suites and correctness criteria

Required qualifications

• BS or MS in Engineering (Mechanical, Chemical, Materials, Electrical), or a related field
• Strong software development skills in Python, including building production services, data pipelines, and APIs
• Familiarity with battery testing and cycler platforms (e.g., Arbin, Maccor, Neware)
• Experience with cloud data infrastructure (e.g., AWS, GCP, or Azure) for storing, processing, and serving large-scale time-series data
• Strong communication and collaboration skills

Nice to have

• proficiency in Rust for building production services
• experience building AI agent harnesses and eval suites
• understanding of lithium-ion cell behavior and safety considerations
• experience with AI coding assistants like Cursor or Claude Code
