Job description

Software Engineer, Energy Storage Platform

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.

What Our Team Does

We build the software platform that powers optimized control and market participation of battery energy storage systems (BESS) — software that runs both on the 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 — both in 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.

What You'll Work On

You'll contribute across the platform, with possible areas of focus including:

• BESS data engineering — telemetry pipelines and stores, feature ingestion and storage for forecasting and optimization
• Simulation and training infrastructure — platforms for running and orchestrating simulations at scale
• Real-time forecast and optimization workflows — orchestrating pipelines that drive BESS operations
• Energy market integration — data ingestion and bid management

Some of the technologies we work with: Kubernetes, Rust, Python, NATS, PostgreSQL/TimescaleDB, SQLite, and more as our system continues to evolve.

What We're Looking For

• Strong software design instincts — you think in systems, reason from first principles, and understand the real-world challenges of building available, reliable, scalable, and secure distributed systems
• AI-accelerated development — you're comfortable using AI tools to move faster, without letting them erode system design or code quality
• Great collaborator — you communicate clearly, listen well, and make the people around you better
• Bias toward action — you take initiative, make progress in ambiguous situations, and don't wait for perfect information
• Systems thinker and owner — you're willing to think and collaborate across team boundaries to make sure the product works well as a whole
• Rigorous about quality — you write well-tested, well-monitored software and iterate on it over time
• We're flexible on years of experience — what matters most is the depth of your thinking and your track record of building things that work.

In accordance with California pay transparency laws, the salary range for this position is listed below. Actual compensation may vary based on a variety of factors, including experience, education, and skills.
