Process Engineer

About Phoenix Tailings Phoenix Tailings is a rapidly growing clean mining and metals production startup focused on building a domestic supply of critical materials. Our Freedom Facility in Rochester, New York will be a commercial-scale rare earth separation facility designed to expand U.S. capacity to process and separate rare earth materials. Rare earths are essential inputs for many of the technologies that power modern life. They are used in high-performance permanent magnets found in electric vehicles, wind turbines, robotics, advanced electronics, aerospace systems, and defense applications. Today, much of the world's rare earth processing and separation capacity is concentrated overseas. Building more of this capability in the United States is important for strengthening domestic supply chains, reducing reliance on foreign processing, and supporting the advanced manufacturing, energy, technology, and national-security industries that depend on these materials. The Freedom Facility will be designed to produce thousands of tons of separated rare earth oxides annually, making Rochester an important part of Phoenix Tailings' expansion of domestic rare earth processing capacity. Why Phoenix Tailings At Phoenix, we believe that nothing great is ever accomplished alone or without the passion of people who push and motivate one another. If you are someone who shares our relentless pursuit of a better future, passion for innovation, and are excited about working with some of the top innovators in the world, then this is the place for you.
