Job Description

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.
Generating net energy plasmas in the SPARC tokamak will involve a skilled team of physicists and engineers designing, building, and operating the tokamak and its many systems.  Candidates will work as part of a combined physics and engineering team to support the final design of SPARC, as well as performing the calculations and developing the tools needed for plasma operations, with an emphasis on early campaigns.
The Scientist – Disruptions will lead science and technology activities related to disruptions, helping SPARC operate robustly and gather the information necessary to design ARC.  SPARC will utilize disruption prediction and avoidance strategies, as well as multiple mitigation actuators in order to both reduce the frequency of disruptions in SPARC and also to inform ARC design and operational plans.  This position will involve interfacing physics and engineering activities to complete the design of SPARC’s massive gas injection system and integrating disruption-relevant algorithms into the plasma control system.  This position will work closely with teams of scientists at MIT and other institutions to coordinate SPARC disruption work across several groups.
The candidate will be a key member of the team that operates SPARC, with a central role in setting operational limits and pushing toward higher machine performance.

This team member will do one or a few of the following:

  • Interface between disruption physics and the plasma control system for disruption avoidance, prediction, and triggering of disruption mitigation
  • Perform electromagnetic and thermal calculations to inform the design of SPARC plasma facing components and diagnostics
  • Provide the physics input necessary to complete the design and commissioning of SPARC’s massive gas injection system
  • Contribute to the specifications for SPARC diagnostics relevant to disruption prediction, evaluation, and understanding
  • Develop physics and engineering root-cause workflows to evaluate and reduce the frequency of disruptions during SPARC operations
  • Identify and fill knowledge gaps by coordinating the work of external collaborators working on disruption physics
  • Prepare for, operate, and analyze data from SPARC in order to produce and learn from the world’s first net energy fusion plasma

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

  • A PhD or masters degree in plasma physics or a closely related field 
  • Experience working with and/or operating tokamaks
  • Demonstrated experience analyzing disruption data on existing tokamaks
  • A strong track record of scientific publication in the area of disruption physics
  • A drive toward practical solutions to integrated physics and engineering challenges
  • A general knowledge of the physics and engineering governing tokamak plasma generation and control
  • A desire for active participation in tokamak design and operations
  • Python

Additional experience and/or qualifications:

  • Experience working with experimental hardware such as diagnostics or disruption mitigation systems
  • Familiarity with workflows for evaluating thermal and electromagnetic loads during disruptions.
  • Experience using free-boundary plasma equilibrium codes
  • Experience developing or evaluating disruption prediction or control algorithms
  • Ability to do activities such as typing or sitting for extended periods of time
  • Willingness to adhere to safety protocols to mitigate hazards such as strong magnets
  • Willingness to travel or work required nights/weekends/on-call occasionally when asked
  • #LI-Onsite

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.
At CFS, we deeply value diversity and are an equal opportunity employer by choice. We consider all qualified applicants equally for employment. We do not discriminate on the basis 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, ordinance, or regulation.
