Description

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. Join the power movement as an Assembly Process Engineer - Contract As a SPARC Assembly Process Engineer, you will help create, define, instruct, and assist in managing the process by which we assemble the SPARC tokamak device. This will include collaborating with the system design teams on the sequence and key steps, organizing and designating how the various sub-assemblies will come together to create the larger whole, identifying assembly methods and tools required, and then writing these steps into work instruction packets for use by the assembly technicians to use in the field. You will work closely and collaborate with the other SPARC teams to find the most efficient, creative, cost-effective, and safest way to assemble each part of the tokamak. You will guide and organize how the giant parts of this multi-million pound “Swiss-watch” come together! This work is conducted within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center and within CFS. #LI-Onsite #CFS-NE At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges. We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law. This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws. What you'll do: Develop plans and work instructions for the successful handling, manipulation, guidance, and general integration of complex, novel, and unique assemblies that make up the SPARC sub-systems Assist a lead field engineer in finalizing the strategy for each assembly step - this requires collaboration with the system teams to find the optimum assembly steps, methods, strategies, safety measures, specifications, custom and off-the-shelf tooling, and other details Develop a working knowledge of CFS ERP and MES systems and ensure that part traceability is integrated into the work instruction steps and throughout the part assembly process Utilize problem solving ability and communication skills when non-conformances and challenges arise in the assembly process Within the work instruction development, ensure tool and personnel access is available as required for system assembly steps Be responsible for the plans of part movement at each step and checking that there are no interferences with other systems during movement and part placement Be responsible for construction of the assembly work instruction packets for all SPARC sub-assemblies, and the incorporation of them into the assembly work orders to create the optimum assembly and testing sequence Provide assistance in development and improvement of the work instruction packet and work order creation process to increase standardization, efficiency, safety, clarity, and overall good communication of the instructions for the success of the assembly process Participate in collaborative work with the assembly engineers, tooling engineers, designers, coordinators, as well as direct personnel performing the Tokamak Assembly during on-site work What we're looking for: High School Diploma At least 5 years technical experience in the integration of complex and large mechanical structures (e.g. aerospace, chemical) and experience in work instruction packet creation Bachelor’s or associate degree in a related field, metrology, high-vacuum projects and processes, experience with manufacturing management software, NX, large Component (>10 Ton) lifting experience Exceptional attention to detail Safety conscious and proactive An ability to clearly express and critique ideas An aptitude to use data to drive decisions An emphasis on elegance and simplicity over complexity The ability to thrive in fast-paced, dynamic environments A drive toward commercially viable solutions Values that align with our company’s values of integrity, execution, impact, and self-critique Must-have requirements: Ability to occasionally lift up to 50 lbs Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics Perform activities such as typing, standing, or sitting for extended periods of time
