Research Metallurgist - Hydrometallurgy

Kingston, ON

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 Overview

  • The Research Metallurgist - Hydrometallurgy will design and execute research and process development programs that enhance the inhouse processing of rare earth elements and expand the technical capabilities.
  • This role is ideal for a hands-on metallurgist who enjoys experimental design, laboratory and pilot-scale testing, data analysis, and translating results into practical improvements for commercial operations.

 

What You Will Be Doing

  • Hydrometallurgical process development: Design, evaluate, and optimize metals recovery circuits including leaching, impurity removal, solid-liquid separation, precipitation/crystallization, solution purification, and reagent/water recycle.
  • Research test programs: Develop bench-scale and pilot-scale test plans using sound experimental design, sampling plans, mass balances, and clear success criteria.
  • Rare earth chemistry: Study extraction, dissolution, selectivity, impurity behavior, phase chemistry, product specifications, and factors affecting recovery and purity for Nd, Pr, Dy, Tb, and related elements.
  • Data analysis and metallurgical accounting: Analyze process parameters, yields, product quality, losses, bottlenecks, and variability; prepare technical reports, dashboards, and recommendations.
  • Scale-up support: Translate lab results into pilot and plant operating guidance, including operating envelopes, process control strategies, troubleshooting plans, and SOP updates.
  • Operational collaboration: Work with plant metallurgists, process engineers, operators, maintenance, environmental teams, and strategic partnerships to support projects, commissioning, optimization, and customer/product requirements.
  • Technical communication: Present results and recommendations to internal stakeholders; document work in high-quality technical memos, reports, test procedures, and presentations.
  • Safety and compliance: Plan and conduct laboratory and plant-facing work in alignment with safe work practices, chemical hygiene, waste management, PPE requirements, and environmental expectations.
  • Team contribution: Support technicians, interns, and cross-functional project teams; contribute outside narrowly defined responsibilities in a fast-moving startup environment.
  • Travel: Travel up to 30% for business purposes to support trials, commissioning, plant troubleshooting, vendor/customer meetings, conferences, and partner engagements.

 

What You Need to Succeed

  • Bachelor's degree in Metallurgical Engineering, Chemical Engineering, Materials Engineering, Chemistry, or a related technical field; Master's or PhD preferred.
  • 5+ years of hydrometallurgy, process development, mineral processing, chemical processing, or critical minerals recycling experience; rare earth experience strongly preferred.
  • Strong understanding of hydrometallurgical unit operations such as leaching, precipitation, crystallization, filtration, thickening, clarification, impurity control, and solution purification.
  • Experience designing test programs, operating laboratory or pilot equipment, interpreting analytical data, and translating results into actionable process improvements.
  • Working knowledge of analytical techniques and sample preparation such as ICP-OES/ICP-MS, XRF, titration, ion chromatography, pH/ORP/conductivity measurements, particle size, and moisture/solids analysis.
  • Ability to perform mass balances, metallurgical accounting, recovery calculations, statistics, and structured data analysis
  • Excellent written and verbal communication skills, with the ability to explain complex chemistry and process data to technical and non-technical audiences.
  • Demonstrated commitment to safety, environmental stewardship, collaboration, respect, and service-minded execution.
  • Ability to travel up to 30% for business purposes and to work effectively in office, laboratory, pilot plant, and industrial plant environments.

 

Preferred Qualifications

  • Direct experience with rare earth element recycling, rare earth mineral processing, critical minerals hydrometallurgy, or magnet recycling.
  • Experience supporting pilot plants, commissioning, process troubleshooting, or commercial plant optimization.
  • Experience with DOE, process simulation, geochemical or aqueous chemistry modeling, or flowsheet development.

Pay Range

$90,000 - $120,000 CAD

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
