Cambridge, MA /
Operations Team – Manufacturing /
Commonwealth Fusion Systems (CFS) is the surest path to limitless, clean fusion energy. Our mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We have created a credible path to an operating fusion power plant in 15 years which leverages our novel collaboration with MIT and funding from strategic and financial investors who share our vision. This begins by developing a new class of high-field superconducting magnets that will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now looking to add talented people to the team who are mission-driven and treat people well, improve our team by adding diverse perspectives and new ways of solving problems, have demonstrated exceptional results through a range of different pursuits, and have skillsets and experience that relate to this role.

The welder is responsible for performing all in-house welding work for cutting edge high-field superconducting magnets and tokamak assemblies. The welder also partners with the welding engineer and R&D engineers to develop the weld geometry and techniques, weld specs, and inspection methods needed for welded assemblies for the SPARC tokamak.

This team member will:

    • Weld and inspect large metallic structures and tooling within specified timelines and budgets 
    • Set up welding processes as per specifications, incl. determining the correct equipment to use and methods based on the requirements
    • Read and analyze drawings and take detailed measurements to plan the project layout
    • Cut and join material
    • Perform hand welding or semi-automated welding. Utilize advanced forms of welding when needed. Weld components in vertical, flat, and overhead positions
    • Provide manufacturability feedback to design engineers for weld geometries and material selection
    • Perform welding equipment qualification trials
    • Troubleshoot and resolve manufacturing discrepancies with a focus on continuous improvement
    • Follow safety procedures at all times 

The ideal candidate will have most, if not all, of these requirements:

    • Documented Training or Certification in most of the following: Blueprint Reading and Fabrication, Oxyacetylene Welding, Cutting, Brazing, Basic Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Advanced Shielded Metal Arc Welding (SMAW)
    • 5+ years' experience as a welder on large structural systems and tooling
    • Experience with large metallic structures and manufacturing processes related to welding
    • Experience in producing welds to pass industry standard requirements

Additional experience and/or qualifications:

    • Experience in advanced welding techniques such as TIP-TIG
    • Experience in pressure vessel welding
    • Experience in structural welding
    • Constant Current (CC) Welding Machines
    • MIG, Stick, TIG, Gas, Plasma Arc and/or Electron Beam and Laser Welding
    • The ability to read and interpret technical drawings and documentation
    • Excellent attention to detail
    • Knowledge of various forms of welding equipment and procedures
    • The capacity to work unsupervised
    • A detailed understanding of mathematical and numerical data and calculations
    • Project and time management
    • Ability to lift up to 50 lbs regularly
    • Perform activities such as stooping, typing, standing, and sitting for extended periods of time
    • Withstand exposure to heat, cold, fumes, and noise
    • Willingness to travel occasionally or do required nights/weekends/on-call
