  • Support system testing, validation, qualification, and commissioning activities.

Required Qualifications
  • Bachelor's degree in Chemical Engineering, Nuclear Engineering, or a related engineering discipline.
  • 10+ years of system design and engineering experience.
  • Strong knowledge of thermodynamics, fluid systems, heat transfer, and mechanical/process system design.
  • Experience developing and maintaining mass and energy balance models using Aspen HYSYS and/or Aspen Plus.
  • Experience reading, interpreting, and developing Piping & Instrumentation Diagrams (P&IDs).
  • Demonstrated experience integrating complex engineering systems across multiple technical disciplines.
  • Strong analytical, problem-solving, organizational, and communication skills.

Preferred Qualifications
