Job summary

Radiant is seeking a Senior Thermofluids Systems Engineer, Power Conversion, to own system-level thermodynamic modeling of our power conversion architecture in El Segundo. You will define operating points, balance performance with constraints, and set boundary conditions for fluid systems and turbomachinery.

You will collaborate with control systems and reactor modeling teams, delivering boundary conditions and plant-level dynamic models for control development.

Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Chemical, or Systems Engineering from an accredited institution.
• 5+ years of experience in thermodynamic/power cycle modeling, systems engineering, or performance engineering.
• Strong working knowledge of thermodynamics and fluid dynamics in power generation cycle design.
• Proficiency in MATLAB, Simulink, or Python for performance and simulation analysis.
• Strong first-principles analytical skills and clear communication.

Responsibilities

• Own system-level thermodynamic performance modeling of the power conversion architecture across startup, shutdown, transients, and off-nominal conditions.
• Develop and maintain interface requirements and boundary conditions for fluid system components and turbomachinery.
• Collaborate with hardware teams to implement architectural changes while balancing performance, cost, weight, schedule, and safety.
• Serve as primary interface to control systems engineering, providing plant-level dynamic models and control-relevant boundary conditions.
• Build and maintain performance models in MATLAB, Python, or Simulink.
• Lead root-cause analysis for cycle performance anomalies using test data and models.
• Perform trade studies to optimize cycle and fluid system architecture against program requirements.
• Own system-level risk analysis (FMEA) for fluid subsystems.
• Communicate clearly with multidisciplinary teams.
