Senior Fluids Systems Engineer

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. Senior Fluids Systems Engineer Radiant is seeking a highly motivated Senior Fluids 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. 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. 5+ years of experience in designing, building, and testing fluids systems. Proficient knowledge in fluid dynamics and thermodynamics. Proficient knowledge of process piping design and testing codes, such as ASME B31.3 and ASME PCC-2. Desired Qualifications & Skills Knowledge of thermodynamic power cycles.
