Job Description

About Redwood Materials

Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling —  keeping critical minerals in circulation and driving the energy transition. Founded in 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.

Software Engineer, ML/Computer Vision (Battery Sorting)

The Battery Sorting team at Redwood Materials is building a world-class, ML-enabled sorting platform that uses computer vision and machine learning to classify and route thousands of end-of-life batteries per hour across diverse chemistries and form factors. This role sits at the intersection of software engineering and machine learning, with direct ownership of the production systems powering automated battery sorting on the factory floor. The ideal candidate is equally comfortable debugging a production incident as iterating on a model, and will have the opportunity to generate patents in automated battery classification. This is a high-impact, highly visible role with immediate real-world application in advancing the energy transition.

Hours

Full-time | Schedule may vary depending on site operational needs; flexibility required

Responsibilities will include:

• Develop, test, and maintain production software systems powering automated battery sorting, spanning ML inference, image acquisition, sensor integration, and hardware-adjacent control interfaces


• Train and deploy computer vision models for battery chemistry classification, including dataset annotation, preprocessing, and evaluation within established data pipelines


• Build and maintain services and APIs that connect ML outputs to downstream systems including MES, HMI, and PLC/controls interfaces


• Own observability across the production software stack through structured logging, metrics dashboards, alerting, and on-call triage for inference pipelines and supporting services


• Monitor model performance in production to catch regressions or distribution shifts and drive iterative improvements through data analysis and retraining


• Contribute to infrastructure-as-code and CI/CD workflows to validate, version, and deploy application code and ML model artifacts to production environments


• Collaborate cross-functionally with Controls, Hardware, Manufacturing, DevOps, and IT teams to translate operational needs into software and model improvements

Desired Qualifications:

• B.S. in Computer Science, Electrical Engineering, or a related field, or equivalent practical experience


• 2+ years of industry experience working with machine learning models, preferably in computer vision


• Hands-on experience with ML frameworks and libraries such as PyTorch and OpenCV


• Experience contributing to production codebases and pipelines with an emphasis on clean, well-documented, and well-tested code


• Experience designing and tracking ML experiments using tools such as MLflow


• Familiarity with edge deployment or model optimization techniques for inference (e.g., quantization, TensorRT, ONNX Runtime) in latency-sensitive or resource-constrained environments


• Experience with OCR, image classification pipelines, or multi-sensor and multimodal fusion


• Experience working in or alongside industrial, manufacturing, or operations environments where software interacts with physical systems


• Strong cross-functional communication skills and ability to prioritize and execute in a fast-paced, dynamic environment


• A passion for sustainability and making the world a better place!

Working Conditions:

• Factory floor environment; work schedule may vary depending on site operational needs and flexibility is required


• Willingness and ability to travel to Reno, NV as needed


• Additional working conditions to be confirmed with Hiring Manager
