Ground Systems engineer (SIL/PIL/HIL specialized)

ispace, inc. is looking for Ground Systems engineer to join our growing team in Tokyo.

The Ground Systems team forms the backbone of ispace’s Test and Flight Operations, responsible for designing, building, and maintaining the full infrastructure required to support mission testing and operations. This includes the Mission Control Center, Mission Control Software, operational tools, and the end-to-end test environments that enable mission readiness.As a Ground Systems Engineer, your work directly enables communication with the spacecraft and underpins every phase of mission test and execution. You play a pivotal role in ensuring that missions are conducted safely, reliably, and efficiently—designing and maintaining the infrastructure, software, and operational workflows that make real-time spacecraft operations possible. Your contributions not only ensure mission success, but also streamline operations and empower flight teams to perform at their best.

As a Ground Systems Engineer specialized in Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) platforms, you will design, develop, and maintain the simulation and validation environments used to test and verify the next generation of ispace spacecraft.

You will play a critical role in enabling a “Test-As-You-Fly” philosophy , ensuring that ground infrastructure and spacecraft testbeds faithfully replicate real mission conditions, providing a realistic and representative environment for validation and operations.
