Propulsion System Layout Engineer

Team: Global Design

Location: Tokyo, Japan

Commitment: Full-time (Regular)

Workplace Type: hybrid

Key responsibilities

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 mission.
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 those technical tasks as showing a better alternative approach if 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 operation 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 to build a strong team with effective communications in the team.
Maintain proactive coordination between the teams to balance and achieve project goal.
Perform 3D CAD-based layout design for integration of propulsion system components and piping.
Design for integration of multiple components within constrained spaces, considering the flow of pressurized gases and propellants, manufacturability, assembly, and testing.

Minimum requirements

Minimum 5 years of experience in 3D CAD-based layout design, including integration of multiple components within constrained spaces.
Experience designing with manufacturability, assembly, and testing considerations in mind.
Experience in fluid system design.
Excellent interpersonal, organizational, and communication skills.
Prior experience in spacecraft development is not required; candidates should be adaptable, comfortable working in a fast-paced environment, and eager to learn new technical domains.
Proactive attitude, strong sense of ownership, and ability to work effectively in a team environment.
Working-level English proficiency; business-level Japanese is a plus.

Preferred Qualifications

Knowledge of mechanical design, stress analysis, material selection, and fabrication processes.
Knowledge of Geometric Dimensioning and Tolerancing (GD&T) and tolerance stack-up analysis methods.
Experience coordinating with external manufacturers.
Experience in mass-production product development under structured design processes, including design reviews and quality control.
Knowledge of pressure drop analysis using dedicated software tools.
Experience with high-pressure fluid systems.
Business-level communication skills in English and Japanese.
