Redwood Materials is building the U.S. stockpile of critical materials and deploying large-scale energy storage systems that power data centers and the nation’s grid.

About the role

The position serves as Redwood's senior technical authority on extractive metallurgy across the company's recycling and refining operations. The role owns the metallurgical basis of design for how Redwood liberates, separates, and refines metals from recycled feedstocks, spanning mechanical separation of heterogeneous feeds, high-temperature processing, hydrometallurgical refining, and electrochemical upgrading of battery metals and other critical minerals. Found on 1752vc Careers, the job board for startup and VC roles.

What they're looking for

  • Bachelor's or advanced degree in Metallurgical Engineering, Extractive Metallurgy, Mining Engineering, Mineral Processing, Materials Science, Chemical Engineering, or a related discipline
  • 15+ years of experience in extractive metallurgy, mineral processing, or metals process engineering, or equivalent depth of expertise
  • Demonstrated ownership of deploying a flowsheet from pilot scale through commercial operation, with accountability for the plant's technical performance
  • Deep industrial-scale experience in pyrometallurgy or hydrometallurgy, experience across both preferred
  • Hands-on experience in an operating plant environment such as a smelter, refinery, or concentrator, with ability to travel to plant sites as required
  • Experience with comminution and physical separation of variable, heterogeneous feedstocks
More about this role

About Redwood Materials

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.
