If that’s you and this role fits, we want to hear from you.

Join the power movement as a R&D Multiphysics Simulation Intern
 
Commonwealth Fusion Systems is seeking an R&D Multiphysics Simulation Intern to join the R&D team in Somerville, MA. The R&D Multiphysics Simulation Intern will work on advancing coupled electromagnetic and thermal circuit model workflows and models of high-temperature superconducting (HTS) magnet components for SPARC and ARC. The role includes collaborating across different departments to analyze experimental data and to validate our models.

Program Details:

  • 13-26 week internship
  • 40-50 hours per week with set hourly salary based on year in school
  • Opportunities on site in Somerville, MA. If an intern is going to be on site, you will be responsible for your own transportation and housing
  • Specific project assignments and required technical skillset will vary based on the team’s existing need.
  • Opportunities available for currently enrolled college students in all levels of schooling from bachelor’s degree to PhD
  • Interns must be authorized to work in the United States for any employer

What you'll do:

    • Analyze cable magnet design concepts for ARC via reduced models capturing global and local effects
    • Test new modules for simulation workflows against independent models & experimental data
    • Understand experimental setups & data to validate & understand physical mechanisms measured
    • Write clean, documented, version-controlled code that contributes to shared simulation tools
    • Present methods and results to the R&D team and summarize the work in a final report

What we’re looking for:

  • Pursuing a degree with a focus in Physics or Engineering (e.g. Electrical, Mechanical, Nuclear) or a related field
  • Coding experience through coursework, research or personal projects (e.g. Python, MATLAB, C++)
  • Foundational coursework in electromagnetism and thermodynamics or heat transfer
  • Proficiency in at least one programming language, preferably Python
  • Working understanding of electromagnetics and heat transfer fundamentals
  • Clear written and verbal communication; able to work independently and in a team

Must-have Requirements:

  • Perform activities such as typing, standing, or sitting for extended periods of time
  • Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics

#LI-Onsite

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.
