Intern - R&D Multiphysics Simulation Intern - Spring or Summer 2027

Commonwealth Fusion Systems•Somerville, MA

4d•Onsite

About The Position

Commonwealth Fusion Systems is seeking an R&D Multiphysics Simulation Intern to join its R&D team in Somerville, Massachusetts. The intern will advance coupled electromagnetic and thermal circuit model workflows and models of high-temperature superconducting (HTS) magnet components for SPARC and ARC. The work includes collaborating across departments to analyze experimental data and validate models. This is a 13–26 week internship, with 40–50 hours per week and an hourly rate based on the intern’s year in school. On-site opportunities are available in Somerville; interns working on site are responsible for their own transportation and housing. Specific project assignments and technical skill requirements may vary according to team needs. Opportunities are available to currently enrolled college students at all levels, from bachelor’s degree through PhD. Interns must be authorized to work in the United States for any employer. The role requires dedication to safety in an industrial environment where hazards may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics. The position also involves activities such as typing, standing, or sitting for extended periods.

Requirements

Be pursuing a degree focused on Physics, Engineering (such as Electrical, Mechanical, or Nuclear Engineering), or a related field.
Have coding experience through coursework, research, or personal projects.
Have foundational coursework in electromagnetism and thermodynamics or heat transfer.
Be proficient in at least one programming language; Python is preferred.
Have a working understanding of electromagnetics and heat transfer fundamentals.
Have clear written and verbal communication skills and be able to work independently and as part of a team.
Be authorized to work in the United States for any employer.
Be able to perform activities such as typing, standing, or sitting for extended periods.
Demonstrate dedication to safety and mitigating industrial hazards.

Responsibilities

Analyze cable magnet design concepts for ARC using reduced models that capture global and local effects.
Test new simulation workflow modules against independent models and experimental data.
Understand experimental setups and data to validate models and understand measured physical mechanisms.
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.
