Mechanical Design Engineer, Big Machines

About Redwood Materials

Redwood Materials was founded in 2017 to create a circular supply chain for electric vehicles and clean energy products, making them more sustainable and driving down the cost for batteries. We’re doing this by developing and deploying new technologies to increase the scope and scale of recycled and sustainable materials in the global battery supply chain.

Mechanical Design Engineer, Big Machines

Do you want to design and build robust, industrial-scale machinery from the ground up? Join the Big Machines team at Redwood Materials, where we develop high-performance equipment—such as 200 ton kilns, meter long knife gates, rotary seals, and complex 30m+ conveyance systems—built to operate reliably at 900°C in some of the most corrosive, debris-laden environments on Earth.

Our team partners closely with engineering leadership to solve large-scale mechanical challenges as we scale cutting-edge technologies that drive the circular battery economy. By increasing the reach of recycled and sustainable materials, we are transforming the global battery supply chain. As a member of the Big Machines team, you’ll collaborate with high caliber engineers to design, fabricate, and deploy critical production assets. We’re looking for creative problem solvers who can tackle complex mechanical systems—people who think both tactically and strategically to deliver durable, long-term solutions. If you’re ready to make a tangible impact on the future of sustainable manufacturing, we want to hear from you.
