Senior Algorithms and Simulation Software Engineer

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 we're working with policymakers, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading 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 Senior Algorithms and Simulation Software Engineer In this role you will be responsible for the design and implementation of state estimation and control algorithms, plus models and simulation frame works necessary to verify those algorithms. Your algorithms will be used in critical real-time applications in the SPARC project, as well as related projects. As a member of the Software Engineering team, you will be a hands-on technical contributor. You will be a champion of writing excellent quality, production-ready code for mission-critical real-time systems. You will collect functional requirements from customers and produce software solutions to meet these requirements. You will work with a variety of engineers to integrate your software into software testbeds, hardware testbeds, and the production tools. You will also contribute to the broader software ecosystem to improve tooling and processes used across the company.
