About the company:

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.

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 over $2 billion in capital – more than any other fusion energy company in the U.S.

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 an Algorithms and Simulation Software Engineer

The SPARC Software team seeks an exceptional software engineer to be a member of the Realtime Algorithms & Simulation group. This team is responsible for high-level tokamak orchestration, collaborating with fusion scientists to develop real-time plasma control algorithms, hardware-in-the-loop testbeds and simulation infrastructure necessary for validation, and develop other safety-critical control software that runs the SPARC tokamak and plant. SPARC senses thousands of physical measurements while controlling millions of amps to superconducting magnets and millions of watts of RF power to the plasma. These closed-loop systems must control at rates substantially greater than 1 kHz and must sample some parameters in the MHz range. The technology platforms involved include real-time Linux, bare-metal microcontrollers, FPGAs, and industrial PLCs. The testbeds and simulation environments must be able to validate software across all these platforms. The team will be responsible for both Hardware-in-the-Loop (HITL) and software-only testbeds. Specific infrastructure you will help develop may include software for test orchestration, deployment to testbeds, evaluation of test success, and automatic integration into continuous integration systems. The team will also develop models or model infrastructure for both real-time simulation (e.g. for HITL or operator training) or offline analysis (e.g. for high-fidelity algorithm development). Finally, the team will work with other software and engineering teams to define end-to-end and other integrated test cases and test plans to validate overall SPARC control software and ensure its adherence to design requirements.
