Mechanical Components Testing and Evaluation Engineer

The engineer will join the newly established Fundamental Technologies Group and lead research and development centered on experiments and evaluation. The role focuses on mechanical elements and components and supports technical problem solving for the small ZERO rocket, with the aim of improving its reliability and ability to reach orbit.

Responsibilities include performance, strength, durability, and dynamic-characteristic evaluations of major rocket components such as turbopumps, valves, piping, and actuators. The engineer will also work on optimizing mechanical elements including rolling bearings, mechanical seals, solid-lubrication tribology, and material properties.

The role involves forming hypotheses about the causes of technical issues and planning experiments to verify and resolve them. Duties also include preparing and setting up experimental equipment and measurement instruments, conducting experiments, analyzing data, considering and judging the causes of observed results, and preparing reports.

The engineer will develop new experimental, measurement, and analysis methods to make unexplained phenomena observable. The role also includes technical information exchange and, when necessary, collaboration with external and internal specialist organizations such as research institutions, measurement-equipment manufacturers, and test-equipment manufacturers.

The group evaluates and analyzes complex technical issues arising during each development phase based on fundamental principles, then feeds the results back to the design and development groups to contribute to development speed and overall rocket reliability. The work location is the Tokyo Second Branch in Koto-ku, Tokyo.
