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 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 Mechanical Engineer – Toroidal Field Coil
Commonwealth Fusion Systems (CFS) collaborates with MIT to leverage groundbreaking high-temperature superconducting (HTS) magnet technology to build compact fusion power plants. As a Mechanical Engineer on the SPARC Toroidal Field (TF) Coil System Winding Pack team, you will act as a "Core Player"—a reliable and versatile contributor executing on mid-to-long-term assignments that are critical to the project's success. You’ll also work closely with peers across the organization - from other HTS magnet systems, R&D, Physics, Quality, Production, Assembly, Program Management - to ensure success of the SPARC mission.
In this role, you will own technical execution of a key Winding Pack subassembly as it transitions from final design to physical reality. You will serve as the technical anchor on the manufacturing floor, using deep mechanical engineering fundamentals to resolve complex non-conformances and validate "as-built" conditions. This position offers a unique vantage point: by mastering the practical challenges of building and testing the SPARC TF coils today, you will build the deep, hands-on intuition required to design the high-field, superconducting magnet systems of the future. We are looking for a self-starter who values continuous learning and is eager to bridge the gap between rigorous analysis and rapid execution.
