Oversee the integration of software components within the virtual infrastructure hosting the ground segment, ensuring proper interfacing with spacecraft systems and external ground elements (e.g., EGSE, PIL components).
Develop and execute test plans, procedures, and configurations, including end-to-end validation of communication and control links.
Support CI/CD activities across the ground segment.
Operations Support
Develop, test, and validate operational procedures.
Participate in training activities and mission rehearsals to achieve certification for on-console operations.
Own and maintain Ground-to-Ground Interface Control Documents (ICDs), and contribute to Space-to-Ground ICDs with ground station providers.
Support on-console operations, including 24/7 shift work and on-call duties during critical mission phases.
Compliance
Collaborate with IT to ensure that the Mission Control Center and ground segment comply with security, data protection, and relevant policies and certifications, as defined by the Chief Information Officer and Information Security Officer.

Language: Professional level English (written and verbal); Business level Japanese for non Japanese candidate will be a plus
Experience: 3+ years of experience in ground operations for space missions (LEO, MEO, Deep Space, etc.)
Simulation & Integration: Experience with SIL, PIL, HIL, or mixed hardware-software environments
Software Skills: Proficiency using Python and Bash; strong expertise in CI/CD tools such as Ansible, Gitlab
Operative systems: Solid knowledge of Linux and Windows operating systems.

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.
