ispace is seeking a highly motivated and talented GNC Systems Engineer to join the System Design Group under the Global Design division, responsible for the design and development of lunar landers and other transportation and/or communication/navigation platforms.
The ideal candidate will have in-depth experience on GNC (AOCS) design, implementation, integration, V&V and operations, good technical knowledge of multiple spacecraft subsystems and experience in the system engineering disciplines for spacecraft design.
This is a unique opportunity to join a truly fascinating project, the first stage of ispace’s plans to perform resource prospecting on the moon. In this position, you will be assigned to one or more of ispace's projects, and join a small, international team of engineers working towards the detailed design and qualification of our first missions.
Candidates with demonstrated "hands-on" experience in some engineering domains and interdisciplinary experience are preferred. Teamwork is valued, and depending on the strengths of each member of the systems engineering team, the responsibilities listed below will be assigned accordingly.
This position is based in Tokyo, Japan and will require relocation for overseas candidates.

ispace, a global lunar resource development company with the vision, “Expand our planet. Expand our future.”, specializes in designing and building lunar landers and rovers. ispace aims to extend the sphere of human life into space and create a sustainable world by providing high-frequency, low-cost transportation services to the Moon. Toward that vision, we aim to build an economic zone between the Earth and the Moon (cislunar) through the commercialization of lunar surface development.
In 2022, we launched our first mission to the Moon. It was the culmination of years of hard work and our first step towards extending human life into outer space. Mission 2, launched in 2025, was the second and final mission of the HAKUTO-R lunar exploration program and featured the RESILIENCE lunar lander carrying the TENACIOUS micro rover, navigating deep space and entering lunar orbit before attempting to land on the Moon. With the completion of the R&D Phase, ispace moves forward, taking the lessons learned from Mission 1 and Mission 2, and transitioning into its “Early Commercialization Phase" with Missions 3 & 4 currently in development.
ispace has business entities in Japan, Luxembourg, and the United States with more than 300 employees worldwide.
