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 we're 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 nearly $3 billion in capital, making us the largest and leading private fusion company in the world. 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 Senior Manager, Manufacturing Engineering will be responsible for leading the manufacturing engineering organization across multiple production sites, including CFS1 and Fusionova, supporting the scale-up of advanced magnet component and assembly manufacturing from development through full-scale production. This leader is responsible for defining and executing the manufacturing engineering strategy across sites, developing high-performing teams and managers, and establishing scalable manufacturing systems to support aggressive production and operational goals. They are responsible for developing and standardizing manufacturing techniques, scaling production capability, driving operational excellence, resolving complex manufacturing challenges, and partnering cross-functionally to ensure manufacturing readiness across all phases of production. WHAT YOU'LL DO: * Lead and develop manufacturing engineering teams across multiple sites, including managers, technical leads, and engineers * Define and execute the manufacturing engineering strategy supporting production, quality, capacity, and cost objectives across CFS1 and Fusionova * Establish standardized manufacturing processes, tooling strategies, work instructions, and operational best practices across facilities * Own process development of the manufacturing line for HTS magnets from low-volume R&D builds through full-scale production * Develop and qualify manufacturing techniques, automation strategies, process flows, and work instructions for superconducting magnet components and assemblies * Drive transition from manual processes to scalable semi-automated and automated manufacturing systems * Organize cross-functional project milestones and schedules to meet company strategic targets and production goals * Communicate manufacturing risks, project status, resource requirements, and operational priorities to senior leadership * Lead resolution of complex manufacturing discrepancies with a focus on continuous improvement, throughput, quality, and safety * Develop manufacturing capacity models, staffing plans, factory layouts, and capital equipment roadmaps to support future factory expansion * Partner with Operations, Quality, Supply Chain, Facilities, and Design Engineering to improve production execution and manufacturing readiness * Implement and standardize DFM (design for manufacturability), PFMEA (process failure mode and effects analysis), statistical process controls, and Lean manufacturing methodologies across sites * Influence make-vs-buy decisions and manage relationships with external vendors and manufacturing partners * Drive implementation of KPIs, operational metrics, and data-driven manufacturing decision making * Build organizational capability through hiring, mentoring, coaching, and developing managers and technical leaders * Foster a culture of accountability, collaboration, urgency, operational excellence, and continuous improvement WHAT WE'RE LOOKING FOR: * Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Electrical Engineering, Industrial Engineering, or related technical field is required * 10+ years’ experience as a manufacturing engineer supporting complex electro-mechanical systems * 5+ years’ experience leading manufacturing engineering organizations, including experience managing managers * Experience leading manufacturing engineering teams across multiple production lines, facilities, or sites * Experience taking products from R&D into production, including development of scalable and automated manufacturing processes * Strong background in process development, tooling, automation, production scale-up, and factory operations * Proven ability to lead cross-functional organizations and drive execution in fast-paced technical environments * Experience developing manufacturing strategies, staffing plans, capital roadmaps, and operational improvement initiatives * Proficiency in work instruction writing, process mapping, capacity modeling, production planning, and manufacturing systems development * High self-motivation and ability to operate effectively in ambiguous, high-growth environments with excellent troubleshooting and problem-solving skills BONUS POINTS FOR: * Master’s degree in Engineering, Manufacturing, Operations, or related field * Experience with superconducting magnets, thermo-mechanical assemblies, machining, welding, and/or VPI (vacuum pressure impregnation) * Experience with advanced manufacturing systems, factory expansion, and production system design * Experience applying Lean Manufacturing and/or Six Sigma methodologies in production environments * Experience implementing MES, ERP-integrated manufacturing systems, or digital manufacturing tools 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 #LI-Onsite At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique.
