Their strength lies in using components effectively within a spacecraft system rather than developing components from scratch.\nKey responsibilities\nCollaborate 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.\nSupport 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.\nSupport 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.\nFind technical conflicts beyond the sub-system level and lead a solution through sub-system and system level discussions.\nSupport the creation and/or the maintenance of the spacecraft propulsion system relevant documents such as -sub-system requirement specification and sub-system design specification.\nSupport FMECA, launcher requirement, and the range safety related to the propulsion system.\nSupport the completion of the design reviews with closing the action items. \nSupport manufacturing, procurement, hardware assembly, integration, testing, and launch operation related to the propulsion system, which may include travel to the sites sometimes.\nEvaluate component level and EPM tests related to the propulsion subsystem. Coordinate with suppliers if necessary.\nPrepare operational plan and input to other sub-system teams of Avionics, Thermal, GNC, and Mission. \nReport status and issues to the team lead and the group manager.\nSupport to build a strong team with effective communications in the team.\nMaintain proactive coordination between the teams to balance and achieve project goal.\nPerform 3D CAD-based layout design for integration of propulsion system components and piping.\nDesign for integration of multiple components within constrained spaces, considering the flow of pressurized gases and propellants, manufacturability, assembly, and testing.\nMinimum requirements\nMinimum 5 years of experience in 3D CAD-based layout design, including integration of multiple components within constrained spaces.\nExperience designing with manufacturability, assembly, and testing considerations in mind.\nExperience in fluid system design.\nExcellent interpersonal, organizational, and communication skills.\nPrior 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.\nProactive attitude, strong sense of ownership, and ability to work effectively in a team environment.\nWorking-level English proficiency; business-level Japanese is a plus.\nPreferred Qualifications\nKnowledge of mechanical design, stress analysis, material selection, and fabrication processes.\nKnowledge of Geometric Dimensioning and Tolerancing (GD&T) and tolerance stack-up analysis methods.\nExperience coordinating with external manufacturers.\nExperience in mass-production product development under structured design processes, including design reviews and quality control.\nKnowledge of pressure drop analysis using dedicated software tools.\nExperience with high-pressure fluid systems.\nBusiness-level communication skills in English and Japanese.","description_format":"text","description_chars":4299,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Japanese","level":"All levels","optional":true},{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Japan","iso":"JP","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Space Services"],"lifecycle":[{"event":"open","at":"2026-09-05T08:36:22Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.678,"p_room":0.28,"age_days":128,"expected_fill_days":57,"reasons":["conf:2","velocity","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/ispace-propulsion-system-layout-engineer","json_url":"https://alion.io/job/ispace-propulsion-system-layout-engineer.json","meta":{"generated_at":"2026-10-26T01:47:24Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":2227,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":7409},"rest":"https://alion.io/mcp/rest/get_company?id=7409"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fispace-propulsion-system-layout-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fispace-propulsion-system-layout-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fispace-propulsion-system-layout-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ispace-propulsion-system-layout-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fispace-propulsion-system-layout-engineer"}]}
