Senior Battery Data Engineer

Job description

Job responsibilities

• 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 located at production sites
• 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 identify inefficiencies, then design and build software or agentic workflows to automate them, utilizing the deterministic tool layer above
• Collaborate with domain experts to define agent eval suites and correctness criteria as agentic automation is introduced

Job requirements

• 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; proactive in working directly with stakeholders to identify workflow bottlenecks and turn them into actionable software priorities
• Bonus: proficiency in Rust for building production services; experience building AI agent harnesses and eval suites; understanding of lithium-ion cell behavior and safety considerations;
