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. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.
Senior Software Engineer, Energy Storage
This position is on a team building the software platform that powers optimized control and market participation of battery energy storage systems (BESS) — software that runs both on site controllers and in the cloud. Our scope spans the full stack: compute infrastructure, telemetry, asset modeling, alerting, feature ingestion and storage for forecasting and optimization, simulation and operational control orchestration, and integration with energy markets. We're a lean team that holds ourselves to high standards in both the quality of what we build and the speed at which we build it. We value collaboration, trust, learning, and engineering excellence, and we genuinely enjoy building great things together.
Responsibilities will include:
- Contribute to BESS data engineering — building and maintaining telemetry pipelines and stores, and feature ingestion and storage systems for forecasting and optimization
- Design, build, and maintain simulation and training infrastructure — platforms for running and orchestrating simulations at scale
- Develop and operate real-time forecast and optimization workflows, orchestrating pipelines that drive BESS operations
- Support energy market integration, including data ingestion and bid management
- Collaborate across the full stack and across team boundaries to ensure the product system works well as a whole
- Write well-tested, well-monitored software and iteratively improve it over time
- Apply AI tools to accelerate development while maintaining high system design quality and code standards
Desired Qualifications:
- Strong software design instincts — thinks in systems, reasons from first principles, and understands the real-world challenges of building available, reliable, scalable, and secure distributed systems
- Comfortable using AI tools to move faster without letting them erode system design or code quality
- Excellent collaborator — communicates clearly, listens well, and makes the people around them better
- Bias toward action — takes initiative, makes progress in ambiguous situations, and doesn't wait for perfect information
- Systems thinker and owner — willing to think and collaborate across team boundaries to make sure the product works well as a whole
- Rigorous about quality — writes well-tested, well-monitored software and iterates on it over time
- B.S. or advanced degree in Software Engineering, Computer Science, or another discipline, combined with 2-5 years of experience in software engineering.
- Experience with relevant technologies a plus: Kubernetes, Rust, Python, NATS, PostgreSQL/TimescaleDB, SQLite
- A passion for sustainability and making the world a better place!
