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.

Essential Duties:

You will be an early member of a new engineering team, taking a hands-on role in the design, development, and integration of a new high-power electromechanical product line at Redwood. You'll be responsible for designing mechanical components related to high power electronics, including thermal management, harnessing, enclosures, structures, and reliability while also collaborating closely with electrical, software, and systems engineering teams.

The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on both technical and leadership challenges. You’re a leader and a doer, excited about working in a dynamic, fast-paced setting, and want to shape the mechanical engineering function within a new department at Redwood. This is a Summer 2026 position.

Responsibilities Will Include:

Execute component-level mechanical design and development of a high-volume, high-power energy conversion product from concept to deployment, including thermal management, structural design, packaging/integration of power electronics, and integration with grid infrastructure
Act as in integral mechanical engineering team member, driving innovation and solving technical challenges at a large scale
Perform mechanical analysis (CFD, FEA, thermal, etc.) to validate designs and ensure performance under real-world conditions
