Rocket Propulsion Engineer

ispace is looking for Propulsion Design Engineer to join our growing team. The ideal candidate will have a broad experience in the mechanical design of the propulsion system of the spacecraft.

Due to large amount of application we receive, only shortlisted candidate will be contacted.

• Collaborate with other sub‑system teams of Structure, Thermal, GNC, Avionics, Operation and AIT, supporting the lander propulsion design to a consistent system for current and future missions.
• Support the propulsion team with technical point of view. Validate analysis and model in the propulsion team, provide hands‑on feedback and modification plan, and intervene on those technical tasks if a better alternative approach is necessary. Prepare the related technical reports, obtaining the approvals from the stakeholders.
• Support propulsion design efforts for spacecraft system development with proposing practical applications such as trade‑off studies, material, component, and manufacturing process selection while watching the feasibility in the project.
• Find technical conflicts beyond the sub‑system level and lead a solution through sub‑system and system level discussions.
• Support the creation and/or the maintenance of the spacecraft propulsion system relevant documents such as sub‑system requirement specification and sub‑system design specification.
• Support FMECA, launcher requirement, and the range safety related to the propulsion system.
• Support the completion of the design reviews with closing the action items.
• Support manufacturing, procurement, hardware assembly, integration, testing, and launch operations related to the propulsion system, which may include travel to the sites sometimes.
• Evaluate component level and EPM tests related to the propulsion subsystem. Coordinate with suppliers if necessary.
• Prepare operational plan and input to other sub‑system teams of Avionics, Thermal, GNC, and Mission.
• Report status and issues to the team lead and the group manager.
• Support building a strong team with effective communications in the team.
• Maintain proactive coordination between the teams to balance and achieve project goals.

• Minimum 3 years experience in spacecraft propulsion design (not ship or airplane)
• Have extensive test experiences with use of propulsion engineering models.
• Have an experience in new industrial development project in aerospace field as a propulsion design engineer.
• Have excellent interpersonal, organizational, and communication skills.
• Be comfortable with change, fast‑pace environment, and learning new things.
• Have extensive experience with CAD software packages and drawing makings for the propulsion components and the jigs.
• Proactive attitude, team player, and strong responsibility for own works.
• Working level of English, Japanese business level is a plus

• Proficiency in Solidworks, FEmap, NASTRAN, or equivalent software packages.
• Have knowledge of mechanical design, stress analysis, material selection, and fabrication processes for spaceflight hardware or equivalent.
• Have knowledge of Geometric Dimension and Tolerance (GD&T) and of the stack‑up calculation method for drawing tolerances.
• Have knowledge of pressure drop analysis using dedicated pressure drop software.
• Familiarity with pipework stand‑off selection, propulsion component bracket design, and pipework.
• Familiar with build verification procedures for spacecraft propulsion system.
• Familiar with NDI and welding process.
• Have experience in coordinating external manufacturers.
• Have an experience of team lead more than one year.
• Speaking and writing skills in English and Japanese.

Only shortlisted candidate will be contacted for interview.
