Mechanical Engineer

Mechanical Engineer Radiant is seeking a highly motivated Mechanical Engineer to join the team responsible for the design, development, and integration of critical mechanical systems for our Kaleidos product.

This role involves hands-on mechanical design and analysis of complex hardware operating in demanding environments.

The ideal candidate has strong first-principles understanding of structures, materials, fluids, and thermodynamics, and enjoys taking designs from concept through testing and production.

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 mechanical components and systems supporting Radiant's power generation and cooling platforms.

* Develop detailed mechanical designs for components and assemblies, including structural parts, housings, rotating or moving elements, and interfaces.

* Perform static and dynamic structural analyses using hand calculations and FEA tools (ANSYS, Abaqus, or equivalent) to evaluate stresses, deformations, and fatigue life.

* Prepare technical reports, design documentation, and presentation materials to support design reviews and decision-making.

* Support the build, assembly, 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 mechanical design and analysis of hardware, components, or mechanical systems.

* Proficiency in CAD and FEA tools (SolidWorks, ANSYS, Abaqus, or equivalent), including working knowledge of GD&T.

* Strong problem-solving skills and the ability to clearly communicate technical concepts.

Desired Qualifications and Skills * Experience supporting power, energy, or industrial systems.

* Knowledge of material selection for high-temperature, high-load, or demanding operating environments.

* Hands-on experience with mechanical testing, instrumentation, or experimental validation.

* Exposure to one or more mechanical engineering focus areas such as structures, mechanisms, heat transfer, or dynamics.

* Familiarity with relevant industry standards (ASME, ISO, API, or similar). * Prior nuclear experience is not required for this role.

Additional Requirements * Willingness to work extended hours and weekends as necessary to accomplish our mission.

* Ability to work 100% onsite at Radiant's El Segundo headquarters.
