Physical Metallurgist

Vulcan Elements is manufacturing American rare-earth permanent magnets for a secure, resilient future. With a focus on national security and economic resiliency, we serve critical industries such as defense, aerospace, and automotive powering a high-technology future. Vulcan Elements is building a team of ambitious professionals committed to Mission Focus, Technical Excellence and Transparency.

As a Physical Metallurgist, you will lead thermodynamic model-supported experimental materials and process development, of high temperature metals production from oxides. You will be responsible for the process definition, continuous improvement, documentation, and scale – up of rare earth metallization.

The ideal candidate will design and execute metallurgical experiments while using thermodynamic modeling to interpret results, predict phase behavior, and accelerate process and materials development. This position works closely with process engineering, R&D, and operations teams to translate fundamental understanding into practical outcomes.

Responsibilities

Design and conduct laboratory and pilot-scale metallization experiments

Continuous, data driven, process improvements, and translation of pilot-scale improvements to full production, prioritizing documentation and management of change.

Optimize salt chemistry, process conditions, and reactor geometry.

Prepare and characterize materials using optical microscopy, SEM/EDS, XRD, and related techniques

Develop experimental plans to validate thermodynamic predictions

Maintain detailed experimental records and analyze results statistically and physically

Design experimental programs to establish reactor kinetics, optimize residence time, and maximize throughput.

Present results regularly to peers and leadership.

Author and maintain formal process documentation suitable for training and execution by operations teams.

Partner with R&D, operations, quality, and EHS teams to ensure chemical processes are:

Safe

Scalable

Cost-effective

Environmentally compliant

Provide technical leadership and mentorship to junior engineers and technicians.

Use FactSage, ThermoCalc, or other CALPHAD tools to calculate phase equilibria, thermochemical properties, and reaction pathways.

Model multi-component alloy and oxide/slag/salt systems to guide experimental design

*Responsibilities and tasks outlined are not exhaustive and may change as determined by the needs of the business*

Qualifications

Master’s Degree or higher in Metallurgical Engineering, Materials Science, Chemistry or a related field

5+ years of hands-on experience in metallurgical or electrochemical process development or production

Proven experience creating clear, auditable, and operator-ready process documentation.

Experience supporting pilot plant or early commercial operations.

Ability to independently design and execute experiments.

Strong technical writing and communication skills.

Strong working knowledge of:

Phase equilibria

Design of Experiments

Analytical techniques (SEM, XRF, ICP, etc.)

Must be a U.S. Person due to required access to U.S. export-controlled information or facilities.

Preferred Qualifications

Experience in startup or scale-up environments

Knowledge of quality systems (ISO, internal technical governance)

Ability to operate as a technical authority without excessive oversight

Knowledge of CALPHAD tools (FactSage, Thermo-Calc, or similar)

Experience with high temperature molten salts

Laboratory Safety and PPE Requirements

This position requires strict adherence to laboratory safety protocols and regulatory guidelines. Employees must consistently wear appropriate personal protective equipment (PPE), including lab coats, safety glasses, gloves, and any additional gear required for specific procedures or chemical handling. The role involves working with potentially hazardous materials, equipment, and processes, and team members must follow all established safety rules, maintain a clean and compliant work area, and promptly report any unsafe conditions. The individual must be able to complete required training, apply proper safety practices, and demonstrate a strong commitment to maintaining a safe laboratory environment.
