Diagnostic Model Developer

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.

The SPARC diagnostic team will be developing nearly 40 types of measurements that will be used in real-time control of tokamak plasmas and to inform the design of ARC.  Our measurement systems include magnetics, interferometry, neutral pressure, x-ray to visible spectroscopy, camera imaging, bolometry, neutrons, Thomson scattering, electron cyclotron emission, reflectometry, Langmuir probes and structural temperature and strain sensing.  While nearly all have completed conceptual design, CFS is looking to grow the SPARC team in order be confident that final designs can accomplish SPARC’s mission goals.  For this, we need your help with developing numerical modeling and a software set of tools, that act as predictive digital twins of diagnostics sub-systems and sensors (i.e., synthetic diagnostics sets).  These software components combine bench top testing of sensors with plasma simulations from the SPARC physics team to characterize the measurement signals that a real diagnostic would produce.  Near-term it will help the diagnostic team iterate on design.  During SPARC operations, contributions will be used in software tools for pre-shot planning, real-time plasma control and inter-shot analysis, and in design scoping and optimization for ARC diagnostics.

You will add to a growing, integrated diagnostic team along with MIT-PSFC partners and fusion community collaborators from around the world.  CFS is looking to build a diverse team to meet our mission goals and encourages applications from existing fusion community members, recent graduates with skills demonstrated through internships or research projects and those interested in cross-industry career changers.   

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.
