This is responsible for monitoring and control of major space program elements, including:\nFlight Products computational environments (including physical and virtual processors);\n\nInterfaces with external equipment (imagers, RF, ISL); and\n\nInterfaces with the spacecraft bus.\n\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 POSIXstandards.\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:\n100% company-paid medical, dental, and vision insurance option for employees and dependents\nFlexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA\n100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance\nFlexible Time Off policy for vacation and sick leave, and 12 paid holidays\n401(k) plan and equity options\nDaily catered lunches and snacks\nInternational exposure to our team in France\nFully paid parental leave; 14 weeks for primary caregiver and 10 weeks for secondary caregiver\nCarrot Fertility provides comprehensive, inclusive fertility healthcare and family-forming benefits with financial support\nOff-sites and many social events and celebrations\nRelocation assistance when applicable","description_format":"text","description_chars":3601,"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 time off","Parental leave","Relocation assistance","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Satellite Manufacturing","Space Services"],"lifecycle":[{"event":"open","at":"2026-09-22T14:34:05Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 5","filings_12m":5,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":142500,"route":null,"cap_exempt":false,"checked_at":"2026-11-11T07:38:50+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.883,"p_room":0.9,"age_days":49,"expected_fill_days":85,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-11-11T05:49:22Z"},"pay":{"stated_usd_annual":225000,"is_top_pay":true},"html_url":"https://alion.io/job/loft-orbital-solutions-onboard-software-engineer-hyperdrive-2","json_url":"https://alion.io/job/loft-orbital-solutions-onboard-software-engineer-hyperdrive-2.json","meta":{"generated_at":"2026-11-11T09:24:12Z","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_verified","counted_by":"address","units_charged":1,"used_today":15540,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4539},"rest":"https://alion.io/mcp/rest/get_company?id=4539"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Floft-orbital-solutions-onboard-software-engineer-hyperdrive-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Floft-orbital-solutions-onboard-software-engineer-hyperdrive-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Floft-orbital-solutions-onboard-software-engineer-hyperdrive-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/loft-orbital-solutions-onboard-software-engineer-hyperdrive-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Floft-orbital-solutions-onboard-software-engineer-hyperdrive-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1114657}},{"tool":"search_jobs","arguments":{"company":"loftorbital.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1114657},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
