Design fusion-plant piping and piping-system R&D, including layouts, materials, stress analysis and 3D CAD. Requires relevant plant or piping experience, ASME/JIS knowledge and intermediate English.
About this role
The Electrical and Electronics Engineer will design electrical facilities and equipment for fusion-related devices, test facilities, fusion power plants and demonstration equipment. Work includes preparing electrical load lists and single-line diagrams; specifying UPS, switchgear, MCCs, distribution boards and transformers; reviewing vendor documents after ordering; designing control panels for motor and heater loads; preparing cable routes, cable schedules, hook-up drawings, and BQ/BOMs; and preparing generator specifications and reviewing post-order documentation. The role also covers specifications for receiving and transforming equipment, subcontractor management, design of SVC and MG storage and compensation systems, PMS design, and project management for electrical design execution.
Required experience includes overseas EPC projects involving specifications, vendor inquiries, technical evaluation and post-order vendor document reviews for electrical equipment such as UPS, switchgear and MCCs, as well as equivalent PMS work. Candidates must have experience preparing electrical-construction drawings and BQ/BOMs, understand expanded connection diagrams, and have designed generators driven by gas turbines, steam turbines or emergency diesel engines. The posting also requires understanding of electrical requirements specific to fusion power equipment, the ability to learn them as needed, understanding of international electrical standards such as IEC, and design experience with extra-high-voltage electrical facilities.
Advanced English, a US Professional Engineer qualification, electrician certification, chief electrical engineer certification, ETAP and AutoCAD are listed as preferred qualifications.
The work concerns fusion power plants and related demonstration facilities. The stated mission context is early fusion realization and decarbonization, with projects from fusion-reactor startups and government-related research institutions.
This is a full-time, indefinite-term position. The listed annual salary range is JPY 5.4 million to JPY 12 million.
