About this role
ispace, inc. is looking for highly motivated Propulsion System Engineer advanced research & development (ARD) group.
This position is based in Tokyo, Japan and will require you to relocate. This is not a full remote position.
Successful candidate will participate in two types of ARD projects:
1) new technology development/demonstration and
2) next generation lunar transportation, infrastructure, and resource utilization system architecture creation from initial concept to system preliminary design level.
This role focuses on high thrust propulsion systems, including earth-storable propulsion and advanced propulsion concepts. You will work within a multidisciplinary, model‑driven design team, developing Python‑based propulsion models, exploring large tradespaces, leading technology demonstration projects, and shaping the propulsion architecture of future ispace vehicles.
It is expected that technical solution concepts start at mid/low technical maturity and you develop them to a CML2+ level (see JPL "concept maturity level" scale).
