Shape the Fuel Design Behind an Advanced Nuclear Reactor

The Opportunity

If you’re an experienced design engineer seeking greater technical ownership, this role puts you at the center of physical fuel design for the KRONOS MMR™, a High-Temperature Gas-Cooled Reactor (HTGR) using ceramic matrix TRISO fuel.

Reporting to the Reactor Fuel Design Manager, you’ll help evolve the fuel architecture by translating engineering analysis, irradiation results, manufacturing constraints, and regulatory feedback into controlled physical designs.

You’ll work across fuel performance, reactor physics, thermal-hydraulics, manufacturing, testing, and regulatory teams—giving you broad technical exposure and direct influence on an advanced reactor program.

Why This Opportunity Stands Out

• Own key aspects of advanced reactor fuel design and configuration • Work directly with TRISO fuel and HTGR technology • Influence design through manufacturing, irradiation testing, and regulatory feedback • Collaborate across multiple reactor engineering disciplines • Take hands-on responsibility for CAD, GD&T, design control, and configuration management

What You’ll Do

• Own and evolve controlled fuel design specifications and physical architecture. • Develop and maintain 3D CAD models, 2D manufacturing drawings, and GD&T. • Translate analysis, test results, regulatory feedback, and manufacturing constraints into…
