Senior Mechanical Engineer, Radiant Nuclear

• The ideal candidate will have a strong background in rotordynamics and bearing selection, along with hands-on experience testing real hardware
• Bachelor’s or Master’s degree in Mechanical Engineering or a related field
• 5+ years of experience in the design and analysis of turbomachinery, rotating equipment, or mechanisms
• Strong understanding of rotordynamic principles and tools (e.g., XLrotor, Dyrobes, or equivalent)
• Excellent problem-solving, technical communication, and organizational skills

Desirable

• Radiant is seeking a highly motivated engineer to join the team responsible for the power generation and primary cooling turbomachinery of our Kaleidos product
• This role involves performing the rotordynamic analysis and bearing selection of high-speed rotating machinery including compressors, turbines, and pumps for high-temperature applications
• You'll design, build, and test turbomachinery for Radiant’s power generation systems
• Perform dynamic analysis of rotor-bearing systems to evaluate vibrational behavior, stability, and resonance characteristics
• Conduct critical speed analysis, Campbell diagram analysis, and stability assessments to optimize rotor system design for minimal vibration and resonance
• Analyze rotor response under transient operating conditions, including startup, shutdown, and off-design operations
• Select appropriate bearing types (e.g., rolling element, fluid film, magnetic) based on operating conditions and performance requirements. Evaluate bearing loads, life, and thermal performance
• Prepare technical reports, design documentation, and presentation materials
• Support the build and testing of prototype, first article, and production hardware
