Commonwealth Fusion Systems (CFS) is looking for dedicated and highly motivated off-shift Quality Engineers to oversee manufacturing process quality for our HTS Magnet production and the SPARC Project. In this high-impact, hands-on role, you will take ownership of process stability and defect resolution on the production floor, ensuring our manufacturing processes yield reliable, first-of-a-kind hardware.
