This is responsible for monitoring and control of major space program elements, including:\nFlight Products computational environments (including physical and virtual processors);\nInterfaces with external equipment (imagers, RF, ISL); and\nInterfaces with the spacecraft bus.\nHyperdrive is the common platform powering every onboard service across our spacecraft.\nThe team builds the core capabilities other onboard services need to run mission logic-from interactions and housekeeping to events, automated fault detection and recovery, and lifecycle management.\nBy making complex spacecraft software consistent, observable, and resilient, Hyperdrive helps teams move faster while keeping missions safe in orbit.\nAbout this role:\nDesign, implement, and refine software with a high degree of ownership, driving impactful features from concept through delivery while ensuring robustness and reliability.\nReview code, provide clear feedback, and enforce adherence to established development processes, style guides, and design standards to maintain consistency and quality across the codebase.\nDesign and implement unit tests for both self-authored and peer-authored code.\nUtilize version control systems to create feature branches, push code, and merge approved code into production branches.\nContribute to the onboard software architecture through design proposals and collaborative review\nParticipate in the review and enhancement of software development processes and design standards.\nCoordinate with downstream teams on the release, distribution and adoption of latest releases.\nIn addition to responsibilities within onboard software, you’ll have the opportunity to directly be involved in operating our on-orbit fleet of satellites.\nMust Haves:\n5+ years' software engineering experience, using programming languages including C/C++ (C++11 or newer) and Python.\nExperience with version control systems such as Git\nExperience with continuous integration tools (e.g., GitLab-CI, Jenkins).\nExperience with build systems (e.g., Make, CMake).\nExperience with library management and ABI /API version control.\nUnderstanding of distributed architecture.\nFamiliarity with networking protocols (e.g., UDP , TCP, IP) and POSIX standards.\nExperience in developing multi-threaded applications.\nNice to Haves:\nFamiliarity with additional programming languages, such as Go or Rust.\nExperience with embedded Linux operation, including Yocto, device trees, systemd, and Linux on ARM platforms.\nProficiency with unit test frameworks (e.g., pytest, Googletest, Unity)\nExperience with middleware framework (gRPC, ZMQ / NATS , etc.)\nExperience with containerization technologies (Docker, K3S , systemd-nspawn)\nSome of Our Awesome Benefits:\nEquity, we want you to have an active role in our success\nUp to 35 days of Paid Time Off (vacations & RTT ) and flexible working hours, we want you to be at your best\nHealth and life insurance, we care about your health\nLunch Vouchers, because let’s be honest, we love food! (we even have a slack channel about it #loft-gourmand )\nCross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences\nCompany and team off-sites and many other events to work & celebrate together\nRelocation assistance to Toulouse when applicable\n*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply, even if you don’t check all the boxes.\nWho We Are\nLoft: Space Made Simple.\nFounded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.\nWe integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.\nWith a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.\nAs an international company your resume will be reviewed by people across our offices so please attach a copy in English.","description_format":"text","description_chars":4778,"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":[]},"benefits":["Equity","Flexible schedule","Life insurance","Relocation assistance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Space & Aerospace"],"lifecycle":[{"event":"open","at":"2026-10-01T21:08:38Z"}],"visa":[],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.295,"p_room":0.55,"age_days":12,"expected_fill_days":10,"reasons":["conf:11","velocity","win:tail","comp:brand"],"computed_at":"2026-10-05T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/spacenexus-onboard-software-engineer-hyperdrive","json_url":"https://alion.io/job/spacenexus-onboard-software-engineer-hyperdrive.json","meta":{"generated_at":"2026-10-06T00:40:12Z","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":814,"day_limit":5000,"remaining_today":4186,"minute_limit":60,"resets_at":"2026-10-07T00:00:00Z"}},"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":2086894},"rest":"https://alion.io/mcp/rest/get_company?id=2086894"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fspacenexus-onboard-software-engineer-hyperdrive"},{"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%2Fspacenexus-onboard-software-engineer-hyperdrive"},{"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%2Fspacenexus-onboard-software-engineer-hyperdrive"},{"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/spacenexus-onboard-software-engineer-hyperdrive\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fspacenexus-onboard-software-engineer-hyperdrive"}]}
