Senior Software Engineer

About Redwood Materials

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.

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.

We're replacing our legacy Oracle ERP and WMS with custom systems at North America's largest battery recycler. You'll be one of the engineers building warehouse management, procurement workflows, ERP integration, and operational applications that power a $3B+ manufacturing operation. After go-live, you'll own and evolve these systems as the company scales. This is a permanent product area, not a project.
