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 a Radiation Optics Engineer

SPARC will be the first of its kind in many ways, including the use of fiber optic sensing arrays inside its magnets to monitor temperature and strain. These sensors will be vital to the longevity of the magnets in SPARC. We are looking for a Radiation Optics Engineer to own the design, execution, and data analysis of optical fiber irradiation and complex optical laser system testing. This role involves heavily diving into literature review, analyses of data, deriving empirical relations, understanding radiation impacts in optical fiber and laser systems, and documenting/presenting results.

The Radiation Optics Engineer will be responsible for handling optical fibers in order to execute complex experimental design setups such as fiber splicing, testing, and incorporation of fibers into complex design features.

The Engineer will also work with a diverse team of engineers, scientists, and work across multiple teams to innovate, problem solve, and develop interfacing optics systems in a complex SPARC environment.

This work is conducted within a multi-disciplinary team of physicists and engineers. Participation and clear, concise communication in design and test activities is necessary to both inform design decisions, prepare prototypes, and execute production.
