Commonwealth Fusion Systems•Somerville, MA

8d•Onsite

About The Position

Commonwealth Fusion Systems is hiring R&D Test Engineering Interns for spring or summer 2027. Interns take on meaningful, challenging assignments supporting the development and testing of novel high-temperature superconducting (HTS) magnet technology and SPARC magnet acceptance testing. Specific assignments and technical skill requirements vary by team. The internship lasts 13–26 weeks and is 40–50 hours per week, with an hourly rate based on the intern’s year in school. Opportunities are on site in Devens, Massachusetts, and Somerville, Massachusetts; interns working on site are responsible for their own transportation and housing. Applicants must be currently enrolled college students, from bachelor’s through PhD level, and authorized to work in the United States for any employer. The role involves working safely around industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics. Full-time interns receive sick time, insurance, retirement matching subject to eligibility, professional growth opportunities, and team-building activities.

Requirements

Currently pursuing a degree focused on Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or Physics.
Prior hands-on hardware experience through an internship, Formula SAE, Rocket Club, machine shop, or equivalent.
Proficiency with basic hardware tools and test equipment such as torque wrenches, multimeters, calipers, saws, drills, taps, and power supplies.
Demonstrated exceptional results through a range of pursuits.
High self-motivation and drive to execute quickly, with excellent troubleshooting and problem-solving skills.
Strong communication skills, including willingness to ask for help, ability to integrate with technical engineers and scientists, and ability to communicate with less technical colleagues such as technicians and supply-chain staff.
Ability to perform activities such as typing, standing, or sitting for extended periods.
Dedication to safety when working around industrial hazards, potentially including heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics.
Authorization to work in the United States for any employer.

Responsibilities

Design and build R&D samples, develop associated manufacturing processes, and execute test operations for risk-mitigation development campaigns involving novel HTS magnet technology.
Design, build, and commission test equipment, collaborating with instrumentation and controls engineers to develop sensors and data acquisition as needed.
Perform structural, electrical, and/or thermal analyses to support R&D sample design and predict test results.
Create and manage design, process, and test documentation, schedules, budgets, bills of materials, and instrumentation indexes; deliver technical update presentations to managers and cross-functional technical teams as needed.
Support SPARC magnet acceptance testing by designing, building, and commissioning upgrades and subsystems within the Magnet Factory.
