Process Engineer

Cyclic Materials is building a resilient circular supply chain for rare earth elements and other critical materials. Through our fully integrated proprietary technology platform, we recover rare earths from end-of-life products and transform them into high-purity materials used to produce new permanent magnets. These magnets are critical to the modern economy, underpinning AI, automotive, e-mobility, electronics, semiconductor, energy, defense, and other advanced manufacturing sectors. Founded in 2021, Cyclic Materials has rapidly become a category leader in rare earth recovery, achieving commercial operations in less than five years. We currently operate facilities in Ontario and Arizona, with further expansion underway in South Carolina. Backed by investment accounts advised by T. Rowe Price Associates, Inc., alongside strategic investors including Microsoft, Amazon, Hitachi Ventures, BMW i Ventures, Jaguar Land Rover’s InMotion fund, Energy Impact Partners, ArcTern Ventures, and Fifth Wall, we are scaling quickly and building the industrial backbone required to meet growing global demand for a secure and sustainable supply of rare earths. We have established an extensive and growing network of commercial partnerships with global industry leaders such as Solvay, Vattenfall, Lime, and VACUUMSCHMELZE, enabling the rapid deployment of recycled rare earth materials into real-world supply chains. Joining Cyclic Materials means tackling complex and exciting challenges at scale alongside a team committed to strong execution and measurable impact. If you are motivated by building critical infrastructure and advancing the circular economy, join us and help accelerate the growth of rare earth recycling.
