Senior Structures Engineer

Senior Structures Engineer

Radiant is seeking a highly motivated Senior 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, detailed 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 mass-efficient transportable shielding systems, container system, and high temperature graphite and metallic systems.

• Conduct trade studies and develop designs to meet program requirements.

• Perform detailed thermomechanical analysis (static strength, durability/fatigue) and dynamic analysis (vibration, shock) 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.
• 6+ years of experience designing structures.
• 4+ years of experience performing stress analysis using both hand calculations and finite element tools (Abaqus, Ansys, FEMAP, 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 resolving thermal expansion issues in designs.
• Experience working with interdisciplinary teams.
• 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.

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.
