Nuclear Metallurgy Engineer

Remote

At Lightbridge, we’re pioneering advanced nuclear fuel technology that’s designed to make reactors safer, more efficient, and more responsive to global energy needs. Our mission is bold and we’re looking for equally bold thinkers to help us bring it to life. If you thrive at the intersection of engineering and regulatory strategy, this is your opportunity to help shape the future of clean energy.

Overview:

The Senior/Principal Nuclear Metallurgy Engineer will provide technical leadership for fabrication development activities supporting the qualification and licensing of Lightbridge Fuel. This role focuses on overseeing fabrication activities conducted with national laboratories, universities, and commercial organizations, ensuring all research and development (R&D) efforts remain technically sound, within scope, and aligned with key strategic milestones. The role will also support the development of a pilot-scale fabrication facility and the implementation of material specifications that define the production of Lightbridge Fuel. The successful candidate will play a critical role in interpreting experimental data, developing material behavior models, and advancing the qualification of next‑generation nuclear fuel.

Responsibilities:

  • Provide technical leadership and oversight for fuel and cladding development projects performed by external research institutions.
  • Manage and monitor contracted R&D efforts to ensure work is performed within scope, on schedule, and in alignment with program objectives.
  • Coordinate with experimental testing projects to produce the test articles required for in-pile and out-of-pile testing of Lightbridge fuel and cladding materials.
  • Collaborate with partners to analyze, curate, and interpret experimental data related to irradiation, temperature, corrosion, and other environmental effects.
  • Use the results of fabrication development activities to produce fuel and cladding fabrication specifications to ensure consistent and reliable production of Lightbridge Fuel.
  • Work as part of a multi‑disciplinary engineering and scientific team supporting the licensing and qualification of Lightbridge Fuel.
  • Author and present technical reports, topical reports, and research publications for internal stakeholders, commercial partners, regulators, and the broader research community.
  • Communicate complex technical results clearly through written documentation and formal presentations.
  • Identify emerging knowledge gaps and lead the planning and execution of future testing and development efforts as material understanding evolves.

Required Experience:

  • Strong foundational knowledge of metallurgical processes, including casting and post-casting processes (e.g., extrusion)
  • One of the following education and experience combinations:
    • B.S. in an engineering or science discipline with 8+ years of relevant non-academic experience
    • M.S. in an engineering or science discipline with 6+ years of relevant non-academic experience
    • Ph.D. in an engineering or science discipline with 4+ years of relevant non-academic experience
  • Demonstrated experience in technical writing and in the presentation of engineering analyses and research findings in professional formats.
  • Ability to work independently with minimal supervision, proactively identifying technical needs and taking initiative.
  • Strong working knowledge of radiation materials science, particularly:
    • Radiation damage and defect evolution in metals
    • Effects of irradiation on mechanical and physical properties
    • Oxidation kinetics and general corrosion behavior

Preferred Qualifications:

  • Expertise in refractory alloy fabrication and processing, specifically zirconium alloys.
  • Familiarity with light water reactor (LWR) environments, including core conditions and associated material challenges.
  • Understanding of the performance and limitations of LWR fuel and cladding systems.
  • Familiarity with behaviors of metallic materials exposed to irradiation and high‑temperature environments.

Lightbridge is committed to supporting the people who power our mission. We offer a comprehensive, competitive benefits program designed to promote well‑being, flexibility, and long‑term growth, including:

•     Competitive salary and performance bonuses, including cash and equity awards
•     Remote‑first work culture with opportunities for travel
•     100% company‑paid health, dental, and vision coverage
•     401(k) with 100% company match
•     Generous time off and family care benefits
•     Up to 32 hours per year of company‑covered professional development course fees


If you’re excited about contributing to work that will help shape the future of clean energy, we encourage you to apply. We look forward to learning more about you and the impact you can make at Lightbridge.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
