Job description

Reporting to a Senior Manager within MFC Reactor Engineering, you will support nuclear reactor modeling and the development of a digital thread that links reactor analyses across multiple physics and engineering domains. You will help develop automated workflows and data pipelines that connect neutronics, thermal-hydraulic, structural, and multiphysics simulations, improving traceability and efficiency throughout the reactor design and analysis lifecycle.

Responsibilities include developing Python-based tools for automation, data management, visualization, and model integration; supporting reactor simulations; and exploring the use of artificial intelligence to enhance coding productivity and analysis workflows. The ideal candidate is interested in combining nuclear engineering, advanced modeling and simulation, software development, and digital engineering to create integrated analysis frameworks that support next-generation reactor design and decision-making.

This team works a 9x80 schedule onsite at our Idaho Falls campus. Start date and duration of internship vary based on project and student availability. You may be eligible for course credit for this internship if approved by your university.

Required:

• Undergraduate Junior or Senior, Master's, or PhD student enrolled full time in a degree program at an accredited college/university studying Nuclear Engineering, Mechanical Engineering, Computer Science, or a closely related field
• A minimum overall 3.0 GPA
• Authorization to work in the U.S. (including CPT and OPT)
• Experience with Python
• Experience with reactor analysis tools such as OpenMC, RELAP, MCNP, SERPENT, Griffin, or the MOOSE framework
• Experience with finite element analysis (FEA) or computational fluid dynamics (CFD)
• Current Resume or CV
• Unofficial Transcripts (include current and completed degree programs)
• Current class schedule and number of credits

The Ideal Candidate Will Possess

• Experience with scientific computing and software development practices
• Familiarity with digital engineering concepts and version control
• Experience with AI-assisted coding tools

Compensation and Benefits:

• Undergraduate Internships ($26.94/hour - $32.41/hour)
• Masters Internships ($35.34/hour - $37.73/hour)
• PhD Internships Pre-Candidacy ($36.83/hour - $39.33/hour)
• PhD Internships Post-Candidacy ($38.65/hour - $41.29/hour)
