Manage fusion equipment and system projects from planning through handover, coordinating schedules, costs, resources, risks, teams, vendors, customers, installation, and testing.
About this role
The Piping Design Engineer will work on piping design and piping-system R&D for fusion plants. Responsibilities include defining material specifications and designing piping layouts while accounting for the high-temperature, corrosion, radiation and thermal conditions specific to fusion plants.
The role also covers stress analysis and structural integrity evaluations, including static, dynamic and thermal-stress assessments. The engineer will create and manage 3D CAD models and drawings using Auto PIPE and CAESAR II, and collaborate with specialists in mechanical, thermal, construction and safety disciplines as well as with suppliers.
Required qualifications include experience in plant or piping design in areas such as power generation, chemical plants or nuclear facilities, and an understanding of piping-related standards including ASME and JIS. Intermediate English is required. Advanced English is welcomed. Additional preferred qualifications are knowledge of fusion or nuclear plants, an understanding of plant safety and related regulations, and experience designing high-temperature-alloy piping or vacuum-system piping.
Applicants are expected to align with the company’s Vision, Mission and Values, actively engage with new technologies, knowledge and different industries, take a proactive approach to trying new things, and maintain an overall view of the plant rather than focusing only on a single specialty.
The position is listed as full-time permanent employment with an annual salary of JPY 5.4 million to JPY 12 million. The salary is paid monthly, discussed according to experience, and may vary based on company performance and individual evaluation. The posting also states that hiring as a contract employee may be possible.
Work locations include the Tokyo headquarters in Ota, Tokyo; the Kyoto Research Center in Kuse-gun, Kyoto; and overseas subsidiaries in the United Kingdom, the United States and Europe, including Germany. For work at the Tokyo headquarters, work from a satellite office in Marunouchi, Chiyoda-ku may also be possible from June 2026. Remote work may be discussed for people living within commuting distance. Domestic and international transfers may be required.
Working hours are 9:00 to 18:00 with a one-hour break. A flextime system may apply depending on business needs. Holidays are Saturdays, Sundays and public holidays, with at least 120 annual holidays; the posting reports 125 days in 2025 and 126 days in 2026. Benefits include social insurance, other welfare benefits, salary increases and special paid leave granted upon joining. Indoor smoking is prohibited, with a smoking room available in the building.
