TerraPower is hiring a Commissioning Engineer for Natrium nuclear-island commissioning and plant operations. The position is described as Commissioning Engineer III and reports to the USO Commissioning Manager.
The engineer coordinates design and commissioning contributors, develops administrative programs and integrated commissioning schedules, and maintains plant and system requirements.
