Develops fluoride-salt-cooled, high-temperature reactor technology to support the transition to clean energy.

What you will do

• Own the design scope for reactor vessel components, interfaces, and hardware packages.
• Develop reactor vessel requirements, design bases, interface definitions, verification plans, drawings, specifications, calculations, and technical reports.
• Lead mechanical design, structural and thermal analyses, pressure-boundary evaluations, and design integration reviews.
• Coordinate spatial, thermal, structural, and functional interfaces with nuclear design, thermal hydraulics, materials, safety analysis, manufacturing, plant integration, and instrumentation and controls teams.
• Support fabrication, inspection, installation, testing, maintenance, supplier oversight, acceptance activities, and resolution of technical issues.
• Maintain configuration and technical change records, assess risks, participate in audits and failure analyses, and mentor junior engineers and interns.

Requirements

• Bachelor’s or advanced degree in Mechanical Engineering, Nuclear Engineering, Materials Engineering, Structural Engineering, or a related discipline.
• 8+ years of relevant experience in mechanical design, nuclear component design, pressure vessel design, high-temperature systems, structural components, or complex hardware development.
• Independent experience leading the design, analysis, fabrication support, testing, or qualification of pressure vessels, reactor vessels, or other safety-significant mechanical systems.
• Experience with engineering documentation, mechanical drawings, specifications, calculations, design reports, test plans, and technical reports.
• Knowledge of mechanical design, structural mechanics, pressure-boundary design, thermal expansion, bolted joints, weldments, high-temperature degradation, creep, fatigue, and creep-fatigue.
• Proficiency with 3D CAD tools such as SolidWorks or AVEVA, engineering analysis methods, FEA, system safety analysis, configuration management, and interface control.

Nice to have
