Senior Battery Data EngineerActive$173K

Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back.

What you'll 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 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

• BS or MS in Engineering (Mechanical, Chemical, Materials, Electrical), or a related field

What they're looking for

• 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
