1d•$100,000 - $160,000•Onsite

About The Position

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy. Combining decades of research, top talent, and new technologies, weâre designing and building commercially viable fusion power plants. And we're working with policymakers and suppliers to build the energy industry of the future. Weâre in the best position to make it happen. Since 2018, weâve raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world. Now weâre looking for more thinkers, doers, builders, and makers to join us. People whoâll bring new perspectives, solve tough problems, and thrive as part of a team. If thatâs you and this role fits, we want to hear from you. Join the power movement as a Manufacturing Engineer We are looking for a hands-on Manufacturing Engineer to captain our weekend operations. You will be the technical anchor for the "4th Shift," ensuring that our production of high-temperature superconducting magnets continues safely and efficiently when the weekday engineering team is offline. This role requires someone who can lead through influence, make sound decisions under pressure, and bring clarity to ambiguity in a fast-moving, First-of-a-Kind (FOAK) manufacturing environment. You will set the tone for the weekend team which will include keeping technicians focused, engaged, and operating at a high level while turning first-time challenges into scalable, repeatable processes. This is a First-of-a-Kind (FOAK) manufacturing environment. We are designing the product while building the machine. Your job is to bring order to that chaos, turning "first encounters" with novel problems into standardized, repeatable processes. The Schedule: Shift: Friday through Monday â¢ Friday 600 am - 2:30 pm â¢ Saturday and Sunday 6:00 am - 6:30 pm â¢ Monday 6:00 am - 2:30 pm Salary Range: $100,000 - 160,000 (includes 10% shift differential) This schedule allows for 3 consecutive days off (TuesdayâThursday) while providing critical coverage during our high-intensity weekend builds.

Requirements

BS in Manufacturing, Mechanical, or Industrial Engineering (or equivalent high-level technical experience)
3+ years of hands-on manufacturing engineering experience
Proficient with NX (CAD) and Teamcenter (PLM)
Experience with Jira, Slack, Odoo (or similar ERP systems)
Strong understanding of manufacturing processes and production systems
Experience in FOAK or rapidly scaling manufacturing environments
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

Nice To Haves

8+ years in high-complexity assembly environments
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)

Responsibilities

Serve as the primary technical leader for weekend operations, keeping the team focused, aligned, and executing with urgency
Make timely, high-quality decisions in ambiguous, high-pressure situations with strong judgment
Balance production demands with safety and quality, including making tough calls such as stopping work when needed
Lead through influence by driving alignment across teams without direct authority
Train, mentor, and elevate technician performance while maintaining accountability in a fast-paced environment
Actively train, coach, and develop technicians on high-precision manufacturing processes
Translate complex engineering requirements into clear, actionable guidance on the floor
Lead through positive influence, building trust and credibility with the team
Close knowledge gaps by reinforcing both the âhowâ and the âwhyâ behind the work
Troubleshoot non-conformances in real time with a structured and decisive approach
Assess severity and take appropriate action:
Resolve process drift independently
Escalate true design or system failures without applying short-term fixes
Ensure issues are properly documented and communicated (Jira, etc.)
Serve as the critical feedback loop between weekend execution and weekday engineering teams
Identify gaps in work instructions and drive process clarity and improvements
Influence upstream teams by providing clear, data-driven feedback from the floor
Maintain the rhythm and flow of production
Ensure strong shift transitions and team readiness
Confirm technicians have the tools, materials, and direction needed to succeed
