Job description

About Radiant
Radiant is an El Segundo, CA-based startup building the world's first mass-produced, portable nuclear microreactors. The company's first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant's unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028.
About the Role
Radiant is seeking a highly motivated Staff Mechanical Engineer to 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:
  • Own end-to-end engineering of fluid systems and components, including compressors, valves, and heat exchangers.
  • Perform complex thermal and fluids analysis to drive design decisions, verify system performance, and ensure structural integrity using first-principle hand calculations and finite element tools.

  • Bachelor's degree from an accredited institution in Mechanical, Materials, Aeronautical, Civil or Structural Engineering.
  • Experience with fluid system architecture design.
  • 7+ years of 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 :
  • Professional Engineer (PE) Mechanical license.
  • Knowledge of thermodynamic power cycles.
  • Prior experience with designing piping system for thermal growth using hand calculations and FEA tools.
  • Experience with process piping design and testing codes, such as ASME B31.3 and ASME PCC-2.
  • 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.
