PH - Test & Commissioning Engineer_Junior level

核融合炉主要装置の研究開発、コンサルティング、設計、製造、輸出

 # Mission

You will take technical ownership of our high-power gyrotron systems throughout the entire acceptance process — from factory testing at our Adogawa facility (Shiga prefecture), through installation and com# Missioning at customer sites, to final handover for operational use.

This role is about more than testing equipment. You will be responsible for ensuring that our systems perform as designed and for seeing them through to successful operation at the customer site. As the final technical checkpoint before delivery, you will play a critical role in ensuring the performance, reliability, and quality of everything we deliver.

Our # Mission is to make fusion energy a practical and sustainable energy source. Achieving this requires not only cutting-edge technology, but also the expertise to ensure that it performs reliably in the real world.

We are looking for someone who wants to take ownership of that final, critical stage — helping bring our technology from development into operation and contributing directly to the commercialization of fusion energy.

 # Key Responsibilities

*   Develop test plans and procedures for gyrotron systems, including the design of test fixtures and instrumentation.
*   Perform millimeter-wave measurements, including output power, frequency, mode patterns, reflected power, and arc detection, and analyze the resulting data.
*   Conduct conditioning operations across the full system, including high-voltage, vacuum, and cooling subsystems, and optimize voltage ramp-up sequences.
*   Serve as the responsible on-site engineer for Factory Acceptance Testing (FAT) in Japan, as well as Site Acceptance Testing (SAT) and com# Missioning at overseas customer sites.
*   Plan the start-up and safety design of new test facilities, including irradiation test ranges, beam dumps, shielding, and interlock systems.
*   Compile and analyze test data, prepare technical reports, and feed findings and lessons learned back into the engineering and design teams.

*Given the broad scope of this role, your specific responsibilities will be determined based on your experience, expertise, and areas of strength.

 # What makes this role unique

*   Global Impact: Take part in the on-site com# Missioning of high-power gyrotron systems for some of the world’s leading fusion projects, and see the technology you work on come to life in the field.
*   Rare Expertise: Develop highly specialized expertise in testing and com# Missioning high-power gyrotron systems — a field with very few experienced engineers in Japan.
*   Mission: Contribute directly to the commercialization of fusion energy by taking ownership of the final stage of delivery, ensuring that our systems meet the required performance and quality standards before entering operation.


##  Additional Information for Applicants
To allow sufficient time for reassessment, we ask candidates not to reapply for the same position within six months of their previous application.
