The Spacecraft Control Subsystem is a core component of our satellite operations, and our top priority is to ensure that the system operates reliably at all times.\nDetails of work\nAs the Spacecraft Control Subsystem is an in-house system, we are not only responsible for its development but also its ongoing operation and enhancement. The Spacecraft Control Subsystem is responsible for creating operational plans for our satellites, generating command sequences, and calculating essential mission-critical data, ranging from orbit propagation and satellite telemetry to mission planning parameters, to support the daily operational workflow.\nIn this position, you will join the Satellite Operation Planning Unit, responsible for the development and operation of the Spacecraft Control Subsystem. Your primary focus will be on developing and enhancing the user-facing web interface and visualization tools used by our operators to manage satellite missions. You will work closely with our mission planning, backend development, and satellite operation teams to translate complex flight dynamics and operation planning data into intuitive dashboards and interactive tools, ensuring that our teams can understand satellite operation plans, and manage daily operations.\nSelling points of this role\nWe are already operating several satellites in orbit, and with our fleet expected to grow rapidly, the Spacecraft Control Subsystem is more critical than ever. In this role, you will do more than just maintain the system; you will be instrumental in evolving its architecture and user experience.\nAs we strive to achieve greater operational efficiency, you will have the unique challenge of reducing manual intervention through better design and automation. By developing the critical interfaces that our operators use daily, you are directly shaping the \"human-in-the-loop\" experience.\nYou will be working at the core of our business, interfacing between the data platform and our mission-critical processing subsystems. You will have a direct impact on our operational capability-every dashboard, visualization tool, and interface improvement you deliver will directly contribute to the safety, speed, and usability of our satellite mission planning process.\nRequirements\nCloud & Architecture\nAt least 3 years of experience in system development on GCP or AWS.\n\nFrontend Development\nStrong experience in modern frontend development (e.g., React, Vue.js) including UI testing strategies.\n\nProficiency in TypeScript/JavaScript.\n\nProven experience building interactive data visualizations or dashboards.\n\nBackend Development (Golang)\nStrong background in Go for backend services.\n\nExperience building gRPC or RESTful APIs within a microservices architecture.\n\nDeep understanding of concurrency patterns and software architecture (e.g., Clean Architecture).\n\nIntegration & Collaboration\nExperience designing and connecting full-stack applications (connecting frontend interfaces to backend data services).\n\nExperience working in a development team of 3 or more members.\n\nCommunication & On-site Presence\nComfortable communicating in English (written and spoken).\n\nAble to commute to our Tokyo head office 2-3 days per week.\n\nPreferred qualifications\nExperience in UI/UX design or creating internal operational tools.\n\nUnderstanding of WebGL or charting libraries (e.g., D3.js, Deck.gl) for satellite visualization such as generating satellite ground track from its orbit parameters (e.g. Two-line element).\n\nComfortable communicating in Japanese, both written and spoken.","description_format":"text","description_chars":4333,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Japanese","level":"Upper-Intermediate (B2)","optional":true},{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Military","Space & Aerospace"],"lifecycle":[{"event":"open","at":"2026-09-22T23:42:07Z"}],"visa":[],"liveness":{"score":84,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.835,"p_room":1,"age_days":39,"expected_fill_days":192,"reasons":["conf:1","win:early"],"computed_at":"2026-10-09T06:01:00Z"},"pay":null,"html_url":"https://alion.io/job/synspective-fullstack-engineer-satellite-opearation-planning-2","json_url":"https://alion.io/job/synspective-fullstack-engineer-satellite-opearation-planning-2.json","meta":{"generated_at":"2026-10-10T00:40:25Z","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","counted_by":"address","units_charged":1,"used_today":1064,"day_limit":5000,"remaining_today":3936,"minute_limit":60,"resets_at":"2026-10-11T00:00:00Z"}},"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":3629},"rest":"https://alion.io/mcp/rest/get_company?id=3629"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsynspective-fullstack-engineer-satellite-opearation-planning-2"},{"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%2Fsynspective-fullstack-engineer-satellite-opearation-planning-2"},{"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%2Fsynspective-fullstack-engineer-satellite-opearation-planning-2"},{"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/synspective-fullstack-engineer-satellite-opearation-planning-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsynspective-fullstack-engineer-satellite-opearation-planning-2"}]}
