• 5+ years of experience in thermal-hydraulics analysis and fluid system design, preferably for nuclear or advanced energy systems
• Proficiency in thermal-hydraulic system codes (e.g., RELAP, TRACE, SAM) or Computational Fluid Dynamics (CFD) software (e.g., ANSYS Fluent, STAR-CCM+)
• Strong understanding of heat transfer (conduction, convection, radiation), fluid mechanics, and two-phase flow
• Experience in component design and sizing for heat exchangers, pumps, and valves
• Knowledge of reactor safety analysis and transient analysis (e.g., Loss of Flow, Loss of Coolant)
• Familiarity with balance-of-plant (BOP) engineering and power conversion cycles
• Experience with verification and validation (V&V) of thermal-hydraulic models
• Strong analytical, communication, and teamwork skills
• Passion for clean energy and a startup-minded approach to problem-solving
