Staff Modeling and Simulation 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 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 Staff Modeling and Simulation Engineer
We’re looking for a Staff Modeling and Simulation Engineer to join our design team to help build next-generation hardware. In this role, you will serve as a lead technical expert for advanced simulations, driving the predictive validation of complex hardware systems.
This role requires a high-level practitioner in multi-physics simulation who can comfortably model complex interactions across thermal, structural, fluid flow, and chemical regimes. If you enjoy solving deeply complex physics problems, applying rigorous modeling standards, and working in a collaborative, fast-paced environment to deliver first-of-a-kind hardware, this is your opportunity to make an impact.
