If that’s you and this role fits, we want to hear from you.
Join the power movement as a Contract Technician - Welding and Assembly
Join a cutting-edge team working to assemble, weld and test high precision electromechanical assemblies — critical to unlocking the future of clean energy. As a (TIG) Welder and Technician, you'll perform complex electromechanical assembly and in-house welding of large-scale metallic structures. This work will also include micro TIG welding on smaller component assemblies. This is a hands-on role in a fast-paced, highly collaborative environment, with a focus on quality, safety, and continuous improvement.
\nWhat you'll do:
- Assemble electromechanical components per detailed work instructions, drawings, and wiring diagrams
- Operate production, testing, and high-powered magnet equipment
- Use calibrated mechanical tools (e.g., torque wrenches, micrometers, calipers)
- Troubleshoot assembly issues and suggest process improvements
- Perform precision soldering, wiring, epoxy potting, injection molding, and vacuum system work
- Collaborate with engineers to refine processes and improve manufacturability
- Weld metallic structures and tooling using GMAW, GTAW, SMAW, and other methods
- Read and analyze blueprints, perform detailed measurements, and plan welding layouts
- Use manual welding equipment to produce welds in various positions (flat, vertical, overhead)
- Weld stainless steel and copper, including pressure-rated and critical applications
- Participate in welding equipment qualifications and inspections
- Provide design feedback on weld geometries and material choices
- High school diploma or equivalent
- 3+ years of experience in electromechanical or electrical/mechanical assembly
- 3+ years of welding experience with structural systems and tooling
- Proficiency with a variety of hand tools, power tools, and measurement devices
- Ability to read and interpret technical documents, blueprints, and schematics
- Documented training or certifications in welding processes (e.g., GMAW, GTAW, SMAW)
- 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

Company at a glance
Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges.
It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply.
We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality.
We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.
As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.
