Job description

We are on a mission to become a leading supplier of critical materials that enable the green energy and technology revolution. Our materials and technologies are required for the electric vehicle, green energy, consumer electronics, and defense industries, and our battery grade lithium and tech metals are needed for chipsets, semiconductors, and 5G.

We have a substantial interest in the Round Top, Heavy Rare Earth, Lithium and Critical Minerals deposit in West Texas. We have also developed the United States’ first rare earth and critical minerals processing facility and we own the only scalable, sintered neo-magnet manufacturing system in the Western Hemisphere. By developing this fully integrated, US-based “mine-to-magnet” critical mineral supply chain, we are poised to become the leading domestic supplier to these industries.

What you can expect:

At USA Rare Earth, we are pioneers and problem solvers, technologists and team players. Together, we:

Build Solutions:

If our task was a simple one, it would already be done. We are creative and solution-oriented, and we think outside the box to solve important problems. We know that a range of expertise and technologies is needed for success, and we work across sectors and alongside customers to deliver world-class solutions in sustainable ways.

Deliver Quality:

When we do things, we do them well. We believe that top-tier quality leads to industry competitiveness and we hold ourselves to the highest quality standards. We move fast when executing, but safety, quality, and excellence always come first.

Lead responsibly:

We have a responsibility to the planet, our consumers, our country, and each other. We put safety at the center of all we do, take accountability for our actions, incorporate sustainable practices in our processes and act with the financial best interest of our investors and consumers in mind.

Win Together:

Establishing a rare earth magnet supply chain is a big undertaking – and getting there is a team effort. We communicate openly, work together and challenge each other in pursuit of our goals. With every step we take we learn and get better.

Position Overview:

The Product Engineer works with Application Engineering and Manufacturing Engineering to design, develop, and enhance products, processes, and systems in alignment with customer requirements and manufacturing capabilities. This role evaluates product objectives and constraints, develops technical specifications, prepares engineering documentation, and supports the full product lifecycle—from concept and modeling through fabrication, assembly, testing, and continuous improvement.

Key Responsibilities:

• Evaluate and analyze product requirements, constraints, and objectives; develop detailed technical and functional specifications for mechanical components and assemblies.
• Identify appropriate materials, components, and manufacturing processes to deliver effective, cost-efficient solutions that meet design intent and production needs.
• Prepare technical documentation including drawings, instructions, specifications, and engineering reports.
• Utilize CAD software and other modeling tools to develop mechanical parts and tooling; communicate conceptual and detailed designs to cross functional stakeholders.
• Support production processes, including equipment tooling or modifications, part manufacturing, and quality assurance.
• Conduct simulations, prototype builds, and testing to evaluate performance, reliability, and safety; collect and analyze data to recommend design improvements.
• Routinely test and evaluate mechanical systems and equipment critical to business operations to ensure safe, reliable, and optimal functionality.
• Collaborate with engineering, production, quality, and operations teams to resolve issues and support continuous improvement.

Knowledge, Skills, and Abilities:

• Strong understanding of mechanical engineering principles, materials, manufacturing processes, and CAD design.
• Ability to analyze requirements, evaluate constraints, and develop effective technical solutions.
• Skilled in technical documentation, communication, organization, and problem-solving.
• Ability to collaborate effectively across functions, support production activities, and manage multiple tasks in a fast paced environment.

Qualifications:

• Bachelor’s degree in Mechanical Engineering or related field required.
• Proficiency in CAD software, mechanical design principles, materials selection, and manufacturing processes.
• Experience with prototype development, mechanical testing, and performance analysis preferred.

Physical Demands:
