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 a Senior Field Mechanical Engineer - Assembly
As the Senior Field Mechanical Engineer on the Assembly Team at CFS, you will be responsible for the management, engineering oversight, and problem-solving of the most complex and unique work-stations of the SPARC assembly process. You will be the central owner and know your part of the assembly process through-and-through, and you help guide the technicians through any issues that arise along the way, coming up with solutions that continue work and assembly moving forward. You will proactively ensure that they have all the tools required for the work, either procuring them off-the-shelf or quickly designing and building small tools and fixtures for use. This also includes the close collaboration with adjacent teams on the Assembly Team, such as creating and incorporating the new process changes with the Assembly Process team, or providing the Metrology team with any assistance or tools needed for the precision alignment of coils and other key structures. This role is on-site at Devens, MA but is a “field” role in the sense that you will be working day-to-day in the central construction hall in the CFS-2 facility where we are building the SPARC Tokamak. At the core, your role is to keep the assembly process moving smoothly in any and all ways, managing the day-to-day changes in strategy or work orders, problem-solving and making tools, and using your engineering skills and knowledge to solve the many complex challenges that arise during the assembly process. You will guide and manage how the giant parts of this multi-million pound “Swiss-watch” come together!
What you'll do:
Lead a team of two to five field mechanical engineers to plan and deliver on near to medium-term objectives for specific workstations within the SPARC Assembly Scope
Translate department-level strategy into actionable group objectives and manageable project timelines
Define and optimize field engineering workflows and internal standards to improve successful solution outcome rate and team efficiency
Oversee the full station scoping life cycle from predecessor/definition to tool and process implementation
Establish and reinforce best practices for mechanical assembly, including standards for aligning, installation, and rework
Manage all aspects of the group's talent, including hiring, training, and setting clear performance expectations
Coach and mentor team members, actively contributing to their technical growth and professional career development
Build relationships across the organization to influence design direction and resolve technical conflicts with stakeholders
Provide design feedback to SPARC sub-system designs with a focus on manufacturing and assembly. Participate in both formal and informal design reviews to ensure what is delivered can be assembled
Assist in the disposition and resolution of non-conformance issues on parts or the process, then working to incorporate and release red-line changes into an updated assembly sequence
Support hands on operations during Tokamak Assembly serving a variety of roles in the process
Work with teammates in a collaborative fashion to receive feedback early and often to ensure all requirements are met. Many SPARC projects involve high loads, vacuum requirements, and complex manipulation requiring the involvement and review of adjacent sub system experts
What we’re looking for:
Civil, Mechanical, or Aerospace Engineering B.S.
2 years of Mechanical Engineering Experience demonstrating project ownership
2 years experience in management or oversight of an in-progress construction, manufacturing, or assembly/integration process
2 years of experience with CAD software
Bonus points for:
6+ years of Mechanical Engineering Experience demonstrating project ownership
4+ years experience in management or oversight of an in-progress construction, manufacturing, or assembly/integration process
3+ years of experience with Siemens NX
2+ years of leading construction or assembly teams on complex assembly projects
Lifting operations experience
Knowledge of welding
Knowledge of piping and tubing construction and joining
Experience with highly complex or delicate assemblies
Experience with assembly or integration in tightly packaged spaces
Experience with fast-paced and dynamic construction, manufacturing, or assembly/integration builds
Must-have Requirements:
Ability to occasionally lift up to 50 lbs
Perform activities such as typing, standing, stooping, climbing or sitting for extended periods of time
Willingness to travel or work required nights/weekends/on-call occasionally for vendor visits during tool fabrication phases
Required onsite 5 days/week when assembly operations with relevant tools are underway, with possible first or second shift assignment
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
