Phoenix Tailings is a rapidly growing clean mining and metals production startup dedicated to sustainable and economic critical metals production. Our mission is to be the world’s first fully clean mining and metals production company—producing the resources required to power the technology of today and tomorrow.
At Phoenix, we’re building more than technology—we’re building the future supply chain for critical and rare earth metals. This work matters. It demands urgency, rigor, and creativity. You’ll join a team that values ownership, technical excellence, and the courage to challenge legacy approaches to mining and metals production.
Phoenix Tailings is looking for a Senior Process Engineer- Hydrometallurgist to lead hands-on process development, optimization, and scale-up of hydrometallurgical systems for critical and rare earth metals production. This role is ideal for someone with deep technical experience in wet chemistry, aqueous processing, leaching, precipitation, separation, purification, and pilot-scale development who wants to build real-world industrial processes, not just model them.
This position will play a key role in translating laboratory results into scalable process designs that support Phoenix Tailings’ transition from R&D to commercial deployment. You will work closely with R&D, engineering, and pilot operations teams to design experiments, troubleshoot complex process challenges, develop operating parameters, and guide junior engineers and scientists.
At Phoenix Tailings, we have an open culture that values learning, and we are looking to grow the team with enthusiastic individuals who share our vision of sustainable mining.
Phoenix Tailings, Inc. is an Equal Opportunity Employer, and we value diversity at all levels. All qualified candidates will receive consideration for employment without regard to race, color, religion, sex (including gender identity, sexual orientation, and pregnancy), national origin, age, disability or genetic information, or any other applicable protected characteristics, and these characteristics will not be a factor for consideration of any work-related decisions (including but not limited to hiring, firing, compensation, and discipline).
Phoenix Tailings is pioneering the future of clean mining and metals production.
We are dedicated to building the world’s first fully clean mining and refining company, producing the critical metals needed for the next generation of technology and infrastructure. By harvesting valuable materials directly from mining tailings, we eliminate waste streams while creating a sustainable and domestic supply of rare earths and other essential resources.
We are already commercially shipping rare earth metals and alloys to magnet customers today, proving both the scalability and impact of our approach. Our breakthrough refining model provides a clean and reliable supply chain, empowering industries from defense and aerospace to electric vehicles, renewable energy, and medical technologies.
Phoenix Tailings has been commercially shipping rare earth metal products since 2023, demonstrating our leadership in bringing sustainable solutions to market.
