Cyclic Materials™ is building a resilient circular supply chain for rare earth elements and other critical materials. Through our proprietary MagCycle℠ and REEPure℠ processes, we recover rare earths from end-of-life products and transform them into high purity materials used in the production of permanent magnets. These materials are critical to the modern economy, including the production of electric vehicles, electronics, AI infrastructure, wind turbines, defense, and advanced manufacturing technologies. Founded in 2021, Cyclic Materials has rapidly progressed from technology development to commercialization. We currently operate facilities in Ontario and Arizona, with a new expansion underway in South Carolina. Backed by US$75 million in Series C financing led by T. Rowe Price, 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 to meet growing global demand for a secure and sustainable rare earth supply. We have established commercial partnerships with global industry leaders such as Solvay, Vattenfall, Lime, and VACUUMSCHMELZE, enabling the deployment of recycled rare earth materials into real world supply chains. In 2025, Cyclic Materials was named one of the Top 10 Climate Tech Companies to Watch by MIT Technology Review. We are growing quickly and building the industrial backbone required for a circular rare earth economy. Joining Cyclic Materials means working on complex and exciting challenges at scale, alongside a team committed to executing and delivering 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. Position Summary The Senior Process Development Engineer will support the development and commercialization of Cyclic’s Hub and Spoke process technologies. This role sits at the interface of R&D, process technology, pilot work, and process engineering. The successful candidate will help build process understanding, organize technical data, support process design development, and improve how knowledge is captured and applied across projects. The successful candidate will develop process understanding from first principles, translate laboratory and pilot results into commercial process designs, and establish the technical standards, design basis, and engineering knowledge required to support future commercial plants. The role will provide the process engineering basis for future FEED, detailed design, commissioning, and operational optimization while building Cyclic's long-term technical knowledge base. This position also plays a central role in mentoring junior engineers and strengthening engineering capability across the organization.   What You Will Be Doing Lead the development of new process technologies from laboratory through pilot and commercial implementation. Develop a deep understanding of core unit operations using first-principles engineering, thermodynamics, reaction engineering, process modelling, and experimental data. Identify technology gaps, technical risks, and opportunities for process innovation. Design, support, and interpret laboratory and pilot test programs. Analyze laboratory, pilot, and operating plant data to support process development and engineering decisions. Translate laboratory and pilot testwork into commercial process designs. Develop scale-up strategies and evaluate scale-up risks. Participate in commissioning, startup, process validation, and performance testing of pilot and commercial facilities. Support process optimization during early commercial operation. Support technology transfer to Engineering, Operations, and Capital Projects. Develop process models, mass and energy balances, design basis documents, and other technical documentation to s
