Commonwealth Fusion Systems is a commercial fusion energy company headquartered in Devens, Massachusetts, and founded in 2018. The firm specializes in the development of high-temperature superconducting magnets and compact tokamak devices, specifically the SPARC net-energy machine and the ARC commercial power plant. It operates through a strategic partnership with the Massachusetts Institute of Technology and focuses on scaling fusion technology to provide carbon-free, baseload power to global energy markets.

Join the power movement as an R&D Production Test Engineer

We’re seeking an experienced Test Engineer to support the testing and de-risking of our cutting-edge HTS magnet technology, playing a key role in advancing fusion energy. Embedded within our R&D organization, you’ll take on a broad range of responsibilities, from developing methodologies and procedures with magnet physicists to conducting root cause analysis alongside manufacturing experts working with complex new materials. This dynamic role demands flexibility, cross-disciplinary collaboration, and the ability to execute tests on tight timelines. You’ll lead the integration and operation of complex test stands, define safety standards, develop and refine procedures, and drive continuous improvement to help achieve our extraordinary milestones in making fusion a reality.

What you'll do:

    • Lead magnet and other test campaigns in cryogenic, vacuum, and high-current environments
    • Develop detailed test procedures and ensure data integrity with robust instrumentation and controls
    • Support improvements to test stands, optimizing for test rate and ensuring data quality
    • Design, analyze, and build test equipment, including mechanical, electrical, and fluid systems
    • Maintain and document test requirements, risks, and safety protocols
    • Manage test schedules, budgets, and technical documentation (P&IDs, CAD designs, schematics, etc.)
    • Improve test processes for repeatability and efficiency
    • Analyze test data, create custom tools for data analysis, and present findings to cross-functional teams
    • Lead anomaly investigations and resolution, collaborating with physicists and engineers

What we’re looking for:

    • Bachelor’s (or higher) in engineering or applied physics, with 2+ years of hands-on testing experience
    • Expertise in test stand operation, data collection, and cross-functional collaboration
    • Strong background in test planning, data analysis, and test equipment design
    • Experience with electromagnetic fundamentals and troubleshooting complex systems
    • A passion for process improvement and innovative problem-solving
    • Excellent communication skills, with the ability to present technical topics clearly
    • Self-motivated, results-driven, and eager to learn

Bonus points for:

  • Experience with structural FEA software, particularly ANSYS and COMSOL
  • Proficiency in using NX and Teamcenter for designing complex test equipment and assemblies
  • Experience with Ignition for developing Human Machine Interfaces
  • Proficiency in using Jira or similar ticket and task tracking software for managing projects and status
  • Experience with large-scale data collection, manipulation, and analysis to derive actionable insights
  • Hands-on experience operating complex test stands for long-duration test campaigns

Must-have requirements:

  • Ability to occasionally lift up to 50 lbs
  • Perform activities such as typing, climbing, standing, stooping or sitting for extended periods of time
  • Willingness to occasionally travel or work required nights/weekends/on-call
  • Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
