Molten Salt Engineer

Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges.

It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply.

We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality.

We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial  fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.

As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.

 

 

 

 

 

Salt chemistry is a critical driver of corrosion, hydrogen speciation, and material behavior under irradiation. As the Blanket System team scales up to larger systems, maintaining precise control over salt chemistry is vital. We are seeking an entry-level Molten Salt Engineer to support our experimental testing operations. Initially, you will focus on executing standard operating procedures (SOPs), conducting routine materials testing, and maintaining rigorous quality controls. As you build familiarity with our systems, your role will expand to include experimental design, test cell design and construction, and leading projects in materials corrosion and blanket health monitoring. Ideal candidates will have a background in chemistry, chemical engineering, or a related discipline.

The Blanket System team has a strong culture of teamwork, supportive safety culture, and pragmatic risk management. We are looking for an engineer who will fit and actively contribute to this culture.
