Tomorrow’s space leaders will not simply launch satellites into orbit, they will be able to move them, reposition them, extend their lifetime, and maximize their performance in space.\nSince 2017, Exotrail has been developing and operating cutting-edge in-space mobility solutions for commercial, institutional, and defense customers. From our high-performance propulsion system spaceware™ to our orbital transfer vehicle spacevan™, we enable satellites to go farther, stay operational longer, and achieve more.\nToday, more than 200 Exotrailers across Massy and Toulouse are working together to make space operations more efficient and sustainable.\nBacked by over €75 million in funding, we are pursuing a clear mission:\nMaking space a sustainable frontier for future generations.\nJob Description\nAt Exotrail, we are developing spacevan GEO, our orbital transfer vehicle for geostationary missions. To verify and validate its avionics functional perimeter, the IOS Avionics team needs equipment simulators: lightweight stand-ins for onboard units that reproduce their interfaces and protocols, so flight software and avionics can be tested on the bench without the real hardware.\nSupervised by an avionics engineer and working within the team, you will take part in designing and developing these simulators and their test tooling. You will start with a first simple equipment model, then progressively take on more complex interfaces, integration on the test bench, and, depending on your progress, embedded development to integrate these equipment into the flight software.\nWhat you'll do\nDevelop equipment simulators in Python, C or C++, running onRaspberry Pi or microcontrollers (STM32, SAM3X…)\n\nImplement communication links such as UART, RS-422/RS-485, Ethernet (TCP/UDP), CAN, SPI/I2C, as well as software-only simulators when no physical link is needed\n\nWrite automated Python tests that exercise the avionics interfaces and support verification and validation activities\n\nSet up and maintain test benches: hardware wiring, network configuration, tooling and integration into the team's workflow\n\nContribute to embedded flight software development to integrate equipment drivers and interfaces, using your simulators to test them\n\nDocument your work and share it with the team\n\nWhat we're looking for\nFinal-year student (Master's or engineering school) in embedded systems, computer science or a related field\n\nSolid skills in C/C++ and Python\n\nHands-on embedded development experience (microcontrollers and/or embedded Linux)\n\nunderstanding of hardware/software interactions: serial links, buses, signals, basic networking\n\nExperience with Git and teamwork\n\nWorking level French, English is a plus\n\nBonus skills\nKnowledge of ground segment/space concepts (TM/TC, CCSDS, ECSS)\n\nTest automation (pytest) and CI/CD\n\nUse of lab equipment (oscilloscope, logic analyzer, power supplies)\n\nA genuine interest in the space domain and the motivation to build a career in this industry\n\nWhat we value\nVersatility and curiosity: you'll learn across many areas of satellite avionics, from flight software and ground segment to testing and hardware\n\nAutonomy, rigor and a pragmatic mindset\n\neam spirit and clear communication within an agile team\n\nWhy Join Exotrail?\nContribute to technology that truly operates in space.\n\nWork on complete systems, from embedded software development to in-orbit operations.\n\nCollaborate with passionate experts across systems, avionics, software, propulsion, and space operations.\n\nTake part in innovative projects within a rapidly growing international company.\n\nMake a direct impact on the space missions and technologies of tomorrow.\n\nWorking Environment\nOffices located in the heart of Toulouse.\n\nComplimentary coffee, tea, and fresh fruit available on site.\n\nWork-Life Balance\nRegular team events and afterworks.\n\nOn-site osteopathy sessions organized at both locations.\n\nRecruitment Process\n1. HR Interview\nDiscussion about your background, motivations, and career aspirations.\n2. Tutor Interview\nConversation focused on the role, team challenges, and your professional experience.\nReady to launch your career beyond Earth? Join Exotrail and help shape the future of sustainable space mobility.","description_format":"text","description_chars":4349,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"French","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Satellite Manufacturing","Space Services"],"lifecycle":[{"event":"open","at":"2026-10-21T16:27:15Z"}],"visa":[],"liveness":{"score":99,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.993,"p_room":1,"age_days":2,"expected_fill_days":79,"reasons":["conf:4","urgency","velocity","win:early","comp:junior"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/exotrail-avionics-equipment-simulators-intern","json_url":"https://alion.io/job/exotrail-avionics-equipment-simulators-intern.json","meta":{"generated_at":"2026-10-24T20:55:43Z","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":30574,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":53096},"rest":"https://alion.io/mcp/rest/get_company?id=53096"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fexotrail-avionics-equipment-simulators-intern"},{"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%2Fexotrail-avionics-equipment-simulators-intern"},{"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%2Fexotrail-avionics-equipment-simulators-intern"},{"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/exotrail-avionics-equipment-simulators-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fexotrail-avionics-equipment-simulators-intern"}]}
