Senior Mechanical Design Engineer

Senior Mechanical Design Engineer

Radiant is seeking a highly motivated Senior Mechanical Engineer to develop new hardware with a team of experienced engineering professionals in a fast-paced startup environment.  The candidate will be responsible for design and analysis of a wide variety of components in support of developing Kaleidos.

Responsibilities & Duties 

• Mechanical Engineering ownership of components and subsystems, such as the following:  
  • Reactor core pressure vessel design per Boiler & Pressure Vessel Code (BPVC) 
  • Reactor internal components and mechanisms.
  • Radiation shielding and thermal insulation.
  • Heat exchangers and other fluid system components.
  • Transportation and assembly tooling.
• Perform detailed thermal and mechanical analysis (static strength, durability/fatigue) to determine structural integrity (margins of safety) using both hand calculations and finite element tools. 
• Perform trade studies to optimize structure and meet program requirements. 
• Develop and execute manufacturing/assembly instructions and test plans. 
  • Create and manage a Bill-Of-Materials (BOM).  
  • Find and develop suppliers for all 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. 
• 3+ years of experience performing stress analysis (static and fatigue) using both hand calculations and finite element tools (Abaqus, Ansys, or similar). 

Desired Qualifications & Skills 

• 3+ years of experience with design of multi-component assemblies in CAD (Solidworks or similar).
• 3+ years of professional experience designing hardware that was manufactured, deployed, and iteratively improved. 
• Solid understanding and application of GD&T.
• Proficiency with both “hand calc” analytical methods and higher fidelity Finite Element based analysis methods.
• Track record of appropriate fidelity selection, based on engineering questions to be answered.
• Ability to derive free-body diagram and control volume-based models for systems with which one was not previously familiar.
• Experience performing CFD analysis for combined fluid/thermal modeling of systems. 
• Experience performing fracture analysis using NASGRO / NASFLA. 
• Experience performing combined structural and thermal analysis of graphite and ceramic structural components. 
• Self-motivated with strong organizational, written, and oral communication skills. 
• Experience with using text-based software development tools.
