What you'll do:
- Technical Mentorship & Training:
- The biggest blocker on the weekend is often the "knowledge gap." You will actively train and develop new technicians on critical, high-precision operations
- Translate complex engineering requirements into teachable moments on the floor. If a technician is unsure, you don’t just give an order; you explain the why and show them the how
- Rapid Problem Solving & Escalation:
- Troubleshoot non-conformance issues in real-time
- Assessment & Action: You determine the severity of the issue. If it’s a simple process drift, you fix it. If it’s a design flaw or critical failure, you contain the issue, document it via Jira, and escalate it to the appropriate Subject Matter Experts (SMEs) rather than applying a "band-aid" fix that compromises the magnet's integrity
- The Weekend-Weekday Bridge:
- Act as the critical feedback loop between the weekend execution team and the weekday Design and Manufacturing teams
- When you encounter a process that is vague or impossible to execute, you red-line the work instructions and drive the change request to ensure the weekday team can update the process
- Hands-on Line Support:
- Maintain the rhythm of the line. Ensure hand-offs between shifts are seamless and that the team has the tools and materials to hit targets
What we're looking for:
- BS in Manufacturing, Mechanical, or Industrial Engineering (or equivalent high-level technical experience)
- A minimum of 3+ years of hands-on manufacturing engineering experience
- Preferred8+ years of experience in high-complexity assembly
- Proficient with NX (CAD) and Teamcenter (PLM)
- Experience tracking issues and production in Jira, Slack, and Odoo (or similar ERP systems)
Bonus points for:
- Experience with insulation systems similar to the electric motor industry (e.g., stator winding, VPI processes, taping, high-voltage isolation)
- Knowledge of statistical process control (SPC) and failure modes and effects analysis (FMEA)
Must-have requirements:
- Ability to lift up to 50 lbs occasionally
- Perform activities such as typing, standing, stooping, and sitting, for extended periods of time
- Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics
- Willingness to occasionally travel or work required nights/weekends/on-call

What We Do
Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.
CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. CFS is now building SPARC, the world's first commercially relevant, net energy fusion demonstration device. SPARC will pave the way for the first fusion power plant, ARC, that will produce power on the grid.
The ultimate mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.
