With these satellites in orbit and a wave of exciting missions launching soon, we are scaling up quickly as a global company.\nWe are looking for a Test Infrastructure Engineer to join the team building and maintaining Loft’s test infrastructure internationally across our Golden, CO, San Francisco, CA, and Toulouse, France sites.\nAbout this role:\nAs a Test Infrastructure Engineer, you will primarily help design, develop, and deploy our test infrastructure and the tools for automating both our hardware and software testing, which will help us scale as a company.Sitting between the spacecraft and all the other teams, you will have a big impact in ensuring that every element of our satellite works without any bugs.We are looking for engineers with a product mindset, who have a good understanding of embedded systems, networking, data exchange protocols, and experience with setting up software infrastructures. Additionally, we are looking for someone who is:\nAble to work independently with some guidance. People owning their work is important to us!\nAble to wear multiple hats as needs arise. We are a small company disrupting an entire industry!\nNot afraid to get out of their comfort zone to explore and learn. Technologies are evolving at rapid rates, and we must stay relevant!\nKey responsibilities include:\n Design, build, deploy, and maintain high-fidelity Hardware-in-the-Loop (HIL) testbeds that emulate spacecraft systems, sensors, and communication links.\n Design, build, deploy, and maintain Electrical Ground Support Equipment (EGSE) that interfaces with space vehicles under Assembly, Integration & Tests, allowing Validation and Verification of spacecrafts and their software before their launch campaigns.\nDevelop tools and frameworks that allow teams to simulate faults, edge cases, and mission scenarios that are difficult or costly to reproduce with physical hardware alone.\nWork closely with systems, software, hardware, and operations teams to understand evolving test requirements and integrate feedback into the platforms.\nMaintain and extend test infrastructure to support continuous integration (CI) pipelines, ensuring every code change is validated with realistic system-level tests.\nTroubleshoot complex system issues spanning software, embedded hardware, networking, and system configuration.\nOur culture at Loft Orbital promotes collaboration and ownership among our developers, fostering efforts hand in hand with other teams, internally and externally.\nMust Haves:\n Master’s degree in Computer Science or a similar field.\n2+ years working with Linux systems, including configuration, debugging, and system-level troubleshooting.\nStrong understanding of networking fundamentals (OSIlayers, packet analysis, data exchange protocols like TCP/IP and UDP).\nHands-on experience with embedded systems or low-level hardware (Raspberry Pi, Arduino, microcontrollers, or similar).\nProficiency in Python (3.9+) for building test automation frameworks, device drivers, or test orchestration tools.\nExperience containerizing applications with Docker.\nFamiliarity with at least one modern CI tool (e.g., Jenkins, GitLab CI, Buildkite, CircleCI) and integrating test pipelines.\nNice to Haves:\nExperience designing or automating complex HIL/SILtestbed, signal conditioning, fault injection, or hardware emulation.\nExperience with “Infrastructure-as-Code” systems, specifically NixOS.\nFamiliarity with networking simulation tools (e.g., network emulators, virtual switches) for testing data flows under realistic mission constraints.\nInterest or experience with hardware test automation frameworks (e.g., custom Python-based test rigs).\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","description_format":"text","description_chars":4390,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule","Life insurance","Relocation assistance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Satellite Manufacturing","Space Services"],"lifecycle":[{"event":"open","at":"2026-11-03T18:48:25Z"}],"visa":[],"liveness":{"score":51,"band":"ok","label":"Likely open","p_open":1,"p_active":0.846,"p_room":0.6,"age_days":81,"expected_fill_days":86,"reasons":["conf:1","velocity","win:late","crowd:"],"computed_at":"2026-11-08T05:47:12Z"},"pay":null,"html_url":"https://alion.io/job/loft-orbital-senior-software-engineer-test-infrastructure-3","json_url":"https://alion.io/job/loft-orbital-senior-software-engineer-test-infrastructure-3.json","meta":{"generated_at":"2026-11-08T17:28:25Z","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_verified","counted_by":"address","units_charged":1,"used_today":36752,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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-senior-software-engineer-test-infrastructure-3"},{"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-senior-software-engineer-test-infrastructure-3"},{"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-senior-software-engineer-test-infrastructure-3"},{"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-senior-software-engineer-test-infrastructure-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Floft-orbital-senior-software-engineer-test-infrastructure-3"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3698619}},{"tool":"search_jobs","arguments":{"company":"loftorbital.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3698619},"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); https://alion.io/mcp with an Alion account has everything.
