Then you’ve come to the right place!\nAt E-Space, we’re focused on bridging Earth and space with the world’s most sustainable low Earth orbit (LEO) satellite network. We’re a team of bold thinkers, ambitious leaders and dynamic doers-and we’re disrupting NewSpace by fundamentally changing the design of legacy LEO space systems to deliver entirely new satellite capabilities at a fraction of the cost.\nWe’re intentional, we’re unapologetically curious and we’re 100% committed-to saving space, to protecting our planet and to turning connectivity into actionable intelligence\nWe are seeking a highly skilled and motivated FSW/Embedded Software Developer to design, develop, and optimize software for customized embedded devices, with a strong emphasis on space-related software and algorithms. The role involves designing and developing software for bare-metal, RTOS, and real-time Linux environments, real-time performance, system reliability, and implementing robust recovery mechanisms. You will also contribute to testing and automation.\nWhat you will be doing:\nCore Development\nEmbedded Software Development: Architect/Design, write, debug, and maintain efficient software for real-time embedded systems, including mission critical Flight Software and communication with other space-specific software subsystems/modules, such as TTC (CCSDS protocol), Power, Thermal, GNC, FDIR, CFDP.\n\nCommunication Protocols and Specifications: Implement protocols used in space-grade software such as UART, CAN, SpaceWire, SPI, I2C, and Ethernet. Experience with Linux bridging, DSA (Distributed Switch Architecture), and L2 protocols such as RSTP/MSTP, HSR, or FRER for redundant network fabrics is highly valued\n\nNetworking and Avionics Fabrics:Design and implement L2 Ethernet networks for inter-board communication on spacecraft, including switch bring up, PHY configuration, and topology design. Configure and debug L2 redundancy protocols (RSTP, HSR, FRER) for fault-tolerant fabrics. Implement deterministic networking using TSN features where mission profiles require bounded latency.\n\nApplication Integration: Integrate and manage provided applications on top of the customized platform software. Design and bring up Ethernet-based avionics networks, including PHY/MAC initialization, switch configuration, and L2 redundancy protocols.\n\nOperational Management: Design and implement efficient memory management, process management, software updates, reprogramming and power saving modes for embedded systems. Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.\n\nTesting and Support\nTest Framework Development: Create and maintain automated testing frameworks for embedded systems, including HIL, SIL, PIL.\n\nSupport: Provide support for debugging of real-time and critical faults.\n\nDebugging and Validation: Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces.\n\nCollaboration and Documentation\nHardware Interaction: Work closely with global software teams to contribute to the new designs and ensure seamless software-hardware integration.\n\nDocumentation: Prepare and maintain technical documentation.\n\nWhat you bring to this role:\nHands-on: Proven record of designing and developing significant working software in aerospace applications. \nProgramming Languages: Proficiency in C/C++ and scripting languages like Shell or Bash; familiarity with Python. \nEmbedded Systems: Experience with embedded and multicore platforms and their toolchains. Experience with Yocto is a big plus. \nCommunication Protocols: Knowledge of key hardware and software protocols such as UART, CAN, SPI, I2C. TCP and UDP. \nUpgrades: Experience with secure firmware updates and reprogramming mechanisms.\nDebugging Tools: Proficiency with debugging tools like JTAG, GDB, and serial debuggers.\nVersion Control: Expertise with Git or similar version control systems.\nBonus points:\nEducation: Bachelor’s or Master’s degree in Computer Science, Electronics Engineering, or a related field. \nFamiliarity with wireless communication technologies (e.g., Wi-Fi, Bluetooth, Zigbee, LoRa).\nFamiliarity with hardware simulation tools and flatsat environments for testing. \nFamiliarity with CI/CD pipelines and automated build/test workflows.\nKey Attributes\nStrong analytical and debugging skills.\nPassion for quality and attention to detail in software development and testing.\nAbility to work collaboratively in cross-functional and global teams.\nCommitment to staying updated with the latest in IoT, embedded systems, and testing automation technologies.\nA willingness to undertake further relevant training.\nAn understanding and commitment to equal opportunities.\nTime management, self-reliance and willingness to learn. \nAdditional Requirements\nThis is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.","description_format":"text","description_chars":5088,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-01T08:47:55Z"},{"event":"reopen","at":"2026-10-14T07:11:13Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.431,"p_room":0.28,"age_days":127,"expected_fill_days":52,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":180000,"is_top_pay":false},"html_url":"https://alion.io/job/espace-senior-embedded-software-engineer-flight-software","json_url":"https://alion.io/job/espace-senior-embedded-software-engineer-flight-software.json","meta":{"generated_at":"2026-10-17T12:01:47Z","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":15882,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":2438005},"rest":"https://alion.io/mcp/rest/get_company?id=2438005"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fespace-senior-embedded-software-engineer-flight-software"},{"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%2Fespace-senior-embedded-software-engineer-flight-software"},{"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%2Fespace-senior-embedded-software-engineer-flight-software"},{"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/espace-senior-embedded-software-engineer-flight-software\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fespace-senior-embedded-software-engineer-flight-software"}]}
