Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy. CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. 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 execute this plan, we are looking to add talented people to the team who are mission-driven and treat people well, improve our team by adding diverse perspectives and new ways of solving problems, have demonstrated exceptional results through a range of different pursuits, and have skill sets and experience that relate 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. This Scientist – Plasma Control position will lead the development, testing, and evaluation of the real-time control algorithms within the plasma control system, working with MIT-PSFC scientists and other collaborators around the world.  The candidate will contribute to innovative, low-latency, robust, real-time control systems, including plasma control and machine protection, and the development of simulation platforms necessary to achieve the mission of SPARC.  This position will work closely with the engineering team that is developing the real-time control and protection systems, with the physics operations team responsible for defining scenarios and actuator interfaces, and with the diagnostics team that provides control inputs.  The position will also contribute to the development of various simulation frameworks, including a SPARC ‘flight simulator’ that will be used to plan SPARC discharges. The candidate will be a key member of the team that operates SPARC, working to improve the control system during SPARC operation and contributing to the SPARC operational plan. This team member will do one or a few of the following: Develop plasma control algorithms for the SPARC plasma control system and coordinate the verification of this system required for safe and robust machine operation Inform the development of the SPARC plasma control system framework and provide guidance to the software engineering team Work with the physics operations team to determine necessary control parameters and the SPARC diagnostics team to determine available measurements Contribute to the creation of a ‘flight simulator’ for SPARC plasmas for pre-shot planning as part of a multidisciplinary team. Perform various plasma physics analyses and simulation as needed to inform the on-going design and operational planning for SPARC and ARC Translate physics calculations to engineering requirements in a mission-driven environment 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 Masters degree or PhD in plasma physics, control engineering, or a closely related field Experience developing, testing, and evaluating control algorithms for tokamak plasma control Experience working with and/or operating tokamaks Experience interacting with low-latency, high-reliability, real-time control systems 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 Experience with Python Additional experience and/or qualifications: Familiarity with the MARTe2 plasma control framework Familiarity with MATLAB Simulink Experience with MIMO controllers, actuator-sharing, and state-machine control schemes Familiarity with real-time machine protection systems 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 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.
