Mechanical Engineer - Turbomachinery

Mechanical Engineer - Turbomachinery

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 mechanical design and analysis of high-speed rotating machinery including compressors, turbines, and pumps for high-temperature applications. The ideal candidate should have strong first principles in structures, fluids, and thermodynamics. Hands-on engineering experience through internships, co-op programs, research projects, or team-based design competitions (e.g., SAE, ASME, Formula SAE) is a strong advantage.

Responsibilities and Duties:

• Design, build, and test turbomachinery for Radiant's power generation systems.
• Develop detailed mechanical designs for turbomachinery components, including rotors, stators, housings, and seals.
• Perform static and dynamic structural analyses using hand calculations and FEA tools (ANSYS, Abaqus, or equivalent) to assess stresses, deformations, and fatigue life.
• Prepare technical reports, design documentation, and presentation materials.
• Support the build and testing of prototype, first article, and production hardware.

Required Qualifications and Skills:

• Bachelor's or Master's degree in Mechanical Engineering or a related field.
• 2+ years of experience in the design and analysis of turbomachinery, rotating equipment, or mechanisms.
• Proficiency in CAD and FEA tools (SolidWorks, ANSYS, Abaqus, etc.), including knowledge of GD&T.
• Excellent problem-solving, technical communication, and organizational skills.

Desired Qualifications and Skills:

• Prior experience with power generation applications.
• Knowledge of material selection for high-temperature, high-speed applications.
• Hands-on experience with turbomachinery testing and/or instrumentation.
• Experience with one or more turbomachinery specializations (structures, heat transfer, rotordynamics, etc.)
• Familiarity with relevant industry standards (API, ASME, ISO).
• Prior nuclear experience is not required for this role.

Additional Requirements:

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.
• Must work 100% onsite at El Segundo HQ.

Total Compensation and Benefits:

Radiant compensates people for impact and invests in those who continue to raise the bar. Radiant's new hire compensation package includes base salary, substantial equity grants, and comprehensive health benefits. Total compensation and level are determined through a rigorous evaluation of interview performance, experience, education, and qualifications, and are designed to support continued growth as scope, responsibility, and impact expand at Radiant.
