Commonwealth Fusion Systems.

CFS is building SPARC, a compact fusion device that aims to demonstrate net energy from fusion for the first time. Their key innovation is using high-temperature superconducting magnets to create stronger magnetic fields, enabling smaller, more practical fusion devices. After SPARC, they plan to build ARC, a commercial fusion power plant. The company has raised billions in funding and is building manufacturing facilities for HTS magnets. Understanding this pathway from science to commercial product shows you grasp the company's strategy.

CFS hires across superconducting magnet engineering, plasma physics, cryogenic systems, power electronics, mechanical engineering, controls and instrumentation, manufacturing engineering, and software. The work spans from fundamental magnet R&D to building actual hardware on aggressive timelines. The multidisciplinary nature means engineers frequently work outside their core discipline. For candidates who want to work on a world-changing technology with near-term deadlines, CFS offers a unique combination of frontier science and startup urgency.
