About Commonwealth Fusion Systems:
Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent and new technologies, we’re designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.
Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.
If that’s you and this role fits, we want to hear from you.
The Materials Department at CFS supports design engineers, supply chain, and manufacturing by selecting materials and processes, unambiguously defining materials and processes, validating and measuring those materials and their properties, and conducting R&D to develop new materials and processes to enable fusion power deployment. The work is undertaken in support of delivering SPARC, the net energy tokamak under construction in Devens, MA, and ultimately in designing the ARC fusion power plant. These devices pose unique materials challenges including neutron fluxes produced by deuterium-tritium fusion, high heat loads, molten salt coolant systems, complex component topologies, high magnetic fields, and high cryogenic mechanical loads. To support this mission, the CFS Materials Department is seeking a combination welder to support the welding engineering team. This team supports welding process development for both in- and out-of-house superconducting magnet and tokamak assemblies. The welding engineering team works collaboratively across disciplines to develop weld geometry and techniques, weld specifications, and inspection methods needed for CFS components.
This team member will:
- Always follow safety procedures
- Develop advanced welding and joining processes for multiple manual, semi-automatic, mechanized, and robotic processes including but not limited to; GMAW, GTAW, FCAW, LBW, EBW, SAW, SW, Torch Brazing, Induction Brazing and hybrid processes
- Conduct welding and joining qualification test on stainless steel, aluminum, copper, refractory and nickel based alloys
- Set up and unbox welding equipment in a laboratory and production setting
- Assist in the training and knowledge transfer of welding processes from R&D to production operations
- Perform destructive and metallographic testing on welded samples for evaluation and analysis
- Provide manufacturability feedback to engineers for weld geometries and tool access
- Troubleshoot and resolve welding discrepancies with a focus on continuous improvement
The ideal candidate will have most, if not all, of these requirements:
- Highschool Diploma
- 5+ years experience as a welder and/or welding operator on large structural systems and tooling
- Experience with fabrication of large metallic structures and advanced processes related to welding
- Proficiency with GMAW, GTAW, FCAW processes and semi-automatic, mechanized and robotic equipment
- Experience with laboratory methods for destructive weld and material analysis
- Knowledge of safety practices as they pertain to welding, cutting, and joining processes
- Strong problem solving skills, ability to approach new problems with creativity
- Ability to work effectively in a multidisciplinary team of engineers, scientists, technical staff, and others
Additional experience and/or qualifications:
- AS in welding or fabrication technology
- Proficiency in LBW, EBW, SAW, SW, Torch Brazing, Induction Brazing and hybrid processes
- Proficiency welding stainless steels, copper, and aluminum alloys
- Aptitude for picking up and learning advanced welding processes and equipment quickly
- 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
- Ability to lift up to 50 lbs regularly
- Perform activities such as stooping, typing, standing, and 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
- Willingness to travel occasionally or do required nights/weekends/on-call
- #LI-Onsite
