Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.
CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, 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. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.
The Subassemblies team is responsible for delivering precision, ultra high vacuum subassemblies for seven major teams that go into the SPARC Tokamak. As a Subassemblies Specialist, you will be the last set of hands and eyes on critical parts; as such, meticulous attention to detail in build quality is necessary. You will draw upon your years of technical experience building complex systems to help streamline workflows and deliver the best possible parts. Once all the subassemblies are built (roughly a two year timeline) you will be uniquely qualified to install the subassemblies into the Tokamak and your role will transition to the Assembly of the machine. This role is truly a once in a lifetime opportunity to use hands-on assembly skills to accelerate the development of fusion energy by ensuring SPARC is built on time and to high quality. The main systems you will be building are high power RF antennas, plasma facing components, port plugs, error field correction coils, vertical stability coils and plasma diagnostics; the bespoke tools used for real-time control of a burning plasma and to achieve SPARC's science mission.

This team member will:

  • Build complex and simple subassemblies and components while maintaining all cleanliness specifications
  • Oversee contract technicians; ensuring they are following work instructions and are delivering quality parts
  • Perform testing and check-outs with helium leak checking and various other check-out equipment
  • Work together with scientists and engineers to refine work instructions
  • Help to finalize design of components that interact with the tooling
  • Assist with precision alignment and installation of active and passive optical systems
  • Actively participate in maintaining mandatory cleanliness of work area and clean room
  • Assist other CFS teams with related skilled work
  • Participate in developing strategies to quickly overcome non-conformances encountered in the field

The ideal candidate will have most, if not all, of these requirements:

  • High school diploma
  • 9 years in a highly technical assembly role; e.g., aerospace/aircraft, racing, semiconductor, oil & gas, laboratory, wind, automotive
  • 2 years leading a team of four people or more
  • Can operate a forklift
  • Experience creating designs for tooling
  • Experience completing large scale projects end to end
  • Ability to use basic machining tools; e.g., lathe/mill
  • Experience using measurement tools
  • Experience using JIRA, Manufacturo, or other software based tracking
  • Experience rigging and lifting heavy components
  • Highly self-motivated, organized, and passionate about their work

Additional experience and/or qualifications:

  • Welding experience is a bonus
  • Knowledge of clean room best practices
  • Knowledge of cryogenic systems
  • Knowledge of six sigma process
  • Ability to occasionally lift up to 50 lbs
  • Ability to perform activities such as sitting, climbing, stooping, typing, and standing for extended periods of time
  • Willingness to occasionally travel for required nights/weekends/on-call
  • Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
  • #LI-Onsite
