Job Description
At ispace U.S., we’re not just going to the Moon—we’re redefining how we get there. Our missions push the boundaries of human and robotic exploration, driven by our belief: “Expand our Planet. Expand our Future.” By providing cost-effective lunar transportation, we are pioneering a future where space is within reach for scientific discovery, commercial ventures, and sustainable exploration.  

With locations in Japan, Luxembourg, and the United States, ispace is rapidly growing and leading the way in lunar exploration and development. Our U.S. branch is based in Englewood, Colorado, and focuses on high-capacity payload lunar landers designed to support future lunar missions. Our team is made up of innovators, problem-solvers, and visionaries committed to making space more accessible and fostering the next generation of space exploration. 

Let’s go to the Moon together! Our team is growing, and we are actively seeking talented individuals who share our passion for space. 

We are seeking a Software & Simulation Test Design Engineer to architect and lead the development of a unified test software framework and simulation that ensures consistency, scalability, and reliability across global engineering teams. This role is central to establishing standardized testing practices, simulation environments, and automation infrastructure that enable high-confidence validation of mission-critical systems. 

You will define test software across the organization—creating a cohesive ecosystem that spans simulation, hardware-in-the-loop (HIL), integration, and system-level testing—while enabling teams in different regions to operate efficiently within a shared framework.
