About this role

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

- 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
