Job description

About the Role

Radiant is seeking a highly motivated Mechanical Engineer, Fluids Systems to help own critical Kaleidos fluid systems from preliminary design through build and production. These systems include the primary loop subsystems and power conversion loop, serving to convert heat from the reactor core into electrical power. You will be responsible for the following: trade studies, component selection, thermal hydraulic analysis, piping design, vendor selection, assembly, and testing. You will have an instrumental impact of fueling the first new commercial reactor design in over 50 years by 2026.

Responsibilities & Duties:

• Help own end-to-end engineering of fluid systems and components, including compressors, valves, and heat exchangers.

• Perform thermal and fluids analysis to drive design decisions, verify system performance, and ensure structural integrity using first-principle hand calculations and finite element tools.

• Perform trade studies to optimize system 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, Materials, Aeronautical, Civil or Structural Engineering.

• Experience with fluid system architecture design.

• Experience in designing, building, and testing fluids systems.

• Proficient knowledge in fluid dynamics and thermodynamics.

• Proficient knowledge of heat exchanger design and analysis methods.

Desired Qualifications & Skills:

• Knowledge of thermodynamic power cycles.

• Prior experience with fluid system modeling via Matlab/Python.

• Experienced in design for manufacturability and ramping up hardware build in a production environment.

• Experienced in designing and operating test stands.

• Takes extreme ownership of work and a high degree of responsibility.

• Excellent communication across multidisciplinary teams.

• Prior nuclear experience in not required for this role.
