Structures Engineer II

Radiant Industries is an El Segundo, CA-based startup developing Kaleidos, a portable, containerized nuclear microreactor. Portable nuclear power with rapid deploy capability can replace diesel generators used today to provide critical asset support for hospitals, datacenters, and military bases or to power microgrids at remote sites. Radiant’s unique, practical approach to nuclear development utilizes modern software engineering to rapidly achieve safe, factory-constructable microreactors leveraging existing, well-qualified materials. Radiant is on a fast track to demonstrate the first fueled operation of a new commercial nuclear reactor design, just two years from now. 

Structures Engineer 

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.   

Responsibilities & Duties  

• 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. 

Required Qualifications & Skills  

• 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). 

Desired Qualifications & Skills  

• 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. 

Employee Benefits for Eligible Employees:

• Stock: Substantial incentive stock plan for all full time, salaried employees.
• Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans.
• One Medical: Sponsored memberships for employees and their dependents. 
• Vision: 100% top tier plan coverage + 50% for dependents.
• Dental: 100% top tier plan coverage, orthodontia extra, 50% for dependents.
• Voluntary Life, Accident, Hospital, Critical Illness, Commuter and FSA are offered as employee contributed benefits.
• Free snacks and drinks onsite. 
• Flexible PTO policy.
