Structural Design Engineer

About the Company

General Matter is enriching uranium in America. 

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.  

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors. 

Ultimately, our work will help power national ambitions and enable a high-energy society. 

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role

As a Structural Design Engineer, you will play a pivotal role in executing a state-of-the-art enrichment facility from concept through commissioning. You will design, analyze, and ensure designs meet regulatory requirements for safety, performance, and compliance. You will have the opportunity to work on a greenfield project collaborating with mechanical engineers, electrical engineers, architects, and both internal and external partners to develop detailed structural designs and specifications. You will wear multiple hats and supporting your design work through vendor activity and constructions administration. This is an exciting opportunity to solve complex problems at scale, manage multiple projects in a dynamic environment, and bring modern enrichment facilities online. 

Responsibilities

• Lead structural design and analysis including establishing structural design criteria, performing detailed calculations, and analyzing systems. 
• Ensure compliance with NRC, ASME, ANSI, and other applicable codes and standards. 
• Collaborate with civil, mechanical, architectural, electrical, and chemical engineers to design and integrate safe and performant structural solutions.
• Prepare and review code-compliant designs up to permit level, create comprehensive drawing sets (Revit/AutoCAD), and produce calculations, specifications, and technical reports for design validation.
• Review and approve work by junior engineers, BIM specialists, and contractors; serve as Engineer of Record (EOR) as needed, ensuring adherence to internal and regulatory quality standards.
• Provide technical guidance during construction and commissioning, including responding to RFIs, city plan checks, submittals, and on-site inspections to resolve design issues.
• Contribute to project concept development, feasibility studies, and scope definition, delivering structural solutions that meet performance, cost, and schedule goals.
