Lead end-to-end development of a lunar lander orbiter system, defining GNC requirements, coordinating subsystem interfaces, managing algorithm performance, and supporting mission operations.
About this role
ispace, a lunar-exploration company, is hiring a Propulsion System Engineer for its advanced research and development group in Tokyo. The engineer takes part in new technology demonstrations and in creating architectures for next-generation lunar transportation and infrastructure from concept to preliminary design, with a focus on high-thrust propulsion in a multidisciplinary, model-driven team. The position requires relocation to Tokyo and is not remote.
The engineer leads propulsion architecture definition and modelling for studies of orbit transfer vehicles, landers and orbital infrastructure, builds Python models for sizing and trade-space analysis, compares and selects main-engine options (pressurisation, propellant management, feed systems, engine cycles), evaluates advanced propulsion technology, supports technology demonstrations through testing and works with structures, thermal, guidance and mission-design colleagues.
Applicants need a bachelor's or master's degree or equivalent in mechanical, aerospace or a related field, 5 or more years of analytical modelling of chemical propulsion, a solid grasp of mission-level propulsion, and 3 years of Python (NumPy, SciPy) or strong MATLAB. Cryogenic or hybrid propulsion experience is preferred.
