Company mission
To bring one of the world's first factory-constructed microreactors to market.
Role
Who you are
- Bachelor’s degree from an accredited institution in Mechanical, Aeronautical, Civil or Structural Engineering
- 2+ years of experience designing structures
- 2+ years of experience performing stress analysis using both hand calculations and finite element tools (Abaqus, Ansys, or similar)
- This position involves access to technology that is subject to U.S. export controls. Any job offer made will be contingent upon the applicant’s capacity to serve in compliance with U.S. export controls
Desirable
- Experience with design of multi-component assemblies in CAD (NX or similar)
- Experience designing hardware that was manufactured, deployed, and iteratively improved
- Experience designing hardware to BPVC requirements
- Experience designing high-temperature hardware where creep must be considered
- Solid understanding and application of GD&T
- Proficiency with both “hand calc” analytical methods and higher fidelity finite element-based analysis methods
- Ability to derive free-body diagrams for systems with which one was not previously familiar
- Self-motivated with strong organizational, written, and oral communication skills
- Experience with using text-based software development tools
What the job involves
- Radiant is seeking a highly motivated Structures Engineer to design and develop critical structures within Kaleidos
- You will solve unique challenges creating efficient and reliable structures that facilitate fission while surviving extreme temperature environments and meeting volumetric constraints
- You will be responsible for the following: trade studies, material selection, structural analysis, assembly, integration, and testing
- You will have an instrumental impact of fueling the first new commercial reactor design in over 50 years by 2026
- Ownership of critical structures such as in-core, high temperature graphite and metallic systems or mass-efficient transportable shielding systems
- Conduct trade studies and develop designs to meet program requirements
- Perform detailed thermomechanical analysis (static strength, durability/fatigue) to determine structural integrity (margins of safety) using both hand calculations and finite element tools
- Develop and execute manufacturing/assembly instructions and test plans
- Create and manage a Bill-Of-Materials (BOM)
- Find and develop suppliers for components
- Own subassembly design, manufacturing, and test schedules
- Own risk analysis (FMEA) for subsystems
- Collect requirements, provide expertise and feedback to engineers in other functional areas via clear, constructive communication
Our take
To support the clean energy revolution, Radiant Nuclear is developing a portable, containerized nuclear microreactor. Once launched, it will have the potential to provide power to remote parts of the world or act as a backup supply to vital infrastructure such as hospitals and data centers.
Typically, these backup systems are powered by diesel generators - making them extremely bad for the environment. Radiant's microreactors could allow the replacement of these generators whilst supplying the same critical asset support, enabling a substantial reduction in carbon footprint.
Having completed the design phase of the project, Radiant has taken a step closer towards realizing its microreactor (known as Kaleidos). The company intends to test a prototype as early as mid-2026 and has secured considerable funding to support its work towards that goal.
