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 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 Scientist - Scenarios and Integrated Modeling

Scientist - Scenarios and Integrated Modeling will develop plasma physics scenarios for SPARC and ARC based on comprehensive integrated simulation and modeling of the core and edge plasma.  Will coordinate with a multi-institutional team of plasma physics experts to develop and improve an integrated modeling toolset, and to employ that toolset for experimental planning and analysis on SPARC.

Commonwealth Fusion Systems is assembling the high-field SPARC tokamak, which aims to be the first magnetic fusion device to achieve net fusion energy, and is predicted to be able to achieve high gain and fusion power up to 140MW.  In parallel CFS is designing and optimizing the ARC fusion power plant, the first of which will be built in Virginia in the early 2030s.   To achieve SPARC’s goals and validate the physics understanding necessary for optimizing ARC, we plan to develop and continuously improve a comprehensive predictive toolchain, including all physics capabilities needed to evaluate plasma scenario performance and robustness.   The person in this role will coordinate and contribute to  the development and testing of this toolchain, and its use in planning and executing experiments on SPARC, as well as in development and optimization of future power plants.   The person in this role will also play a key role in defining plasma operation goals, identify optimal operation scenarios for each goal, and participate directly in execution and analysis of SPARC operations.

What you'll do :

• Refine, optimize, and validate a comprehensive integrated modeling toolset capable of predicting plasma performance and dynamics
• ➢  Toolset will include models of : core turbulent and neoclassical transport, H-mode pedestal and L-mode edge, coupling to boundary, ICRH heating, energetic particle physics, MHD stability, and impurity transport
• ➢  Toolset will include very rapid execution workflows appropriate for control, rapid execution workflows appropriate for experiment planning and optimization, as well as higher fidelity models for offline analysis and deeper exploration of critical physics
• Work closely with a multi-institutional team of experts to incorporate state-of-the-art physics capabilities, and validate models
• Employ integrated modeling tools to plan and execute plasma pulses to achieve key goals including net fusion power on SPARC, and continuously improve toolset as new data becomes available
• Identify, execute, and continuously improve operational scenario for achieving SPARC goals
• Work closely with physics, diagnostics, operations, plasma control, and software teams to design and execute plasma scenarios on SPARC
• Contribute to physics design and optimization of ARC
