As a Senior Electrical Systems Engineer, you will define the electrical hardware that powers and controls our next-generation fusion machines. You will work at the architecture level to ensure electrical subsystems, including power distribution, controls interfaces, sensors, and communication networks, function together as a coherent and reliable platform. In this role, you will lead architectural decisions, own requirements and interfaces, and drive verification and hardware bring-up. You will work closely with engineering, test, and commissioning teams to translate technical objectives into implementable designs and ensure those designs perform as intended during testing and deployment. This role blends architecture development, requirements ownership, and hands-on hardware work, and is well suited for engineers who enjoy working across disciplines while remaining closely connected to the physical system.
