We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures.\nWHO WE ARE:\nWe’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy.\nWHO YOU ARE:\nAstro Mechanica is seeking a Senior Ground Software Engineer (Telemetry & Control) to join our growing team. The ideal candidate is excited to own all of our aircraft’s data from the moment it leaves the plane until a command goes back to it: everything from the aircraft radio down. You will architect the end-to-end system that ingests, processes, stores, and visualizes flight telemetry in Mission Control, observes the health of the aircraft, and commands the plane. This is not a big-data problem; the data is modest in volume but complex and time critical, and it should reach an operator’s screen within one second of leaving the aircraft. Your work at Astro Mechanica will be fast-paced in a dynamic startup environment and will have a direct impact on our mission.\nWHAT YOU’LL DO:\nArchitect and build the end-to-end ground data pipeline, from telemetry ingestion off the radio link through real-time processing, storage, backend APIs and business logic, to front-end visualization in Mission Control\n\nDrive low latency across the entire system, not just one stage, targeting roughly one second from aircraft to operator display\n\nDesign for fault tolerance so that a failed network path, a crashed service, or a cloud region outage never puts the aircraft at risk\n\nSelect and operate the right database technologies, including time series databases, for flight telemetry\n\nBuild the tools operators use to monitor aircraft health and command the plane\n\nKeep the pipeline clean and simple enough that the team can reason about it end to end\n\nWork closely with flight software and other engineering disciplines to define the interfaces between the aircraft and the ground\n\nWHAT WE’RE LOOKING FOR:\nBachelor’s degree in Computer Science, Engineering, Math, or a Science discipline and 5+ years of professional software development experience\n\nExperience building real-time data or telemetry ingestion and processing systems\n\nExperience implementing a cloud stack that ingests data, stores it in a database, and processes it to serve an application (web, mobile, or otherwise)\n\nHands-on experience with time series databases and a strong understanding of the trade-offs between database technologies and data ingestion approaches\n\nExperience designing low-latency, high-reliability systems, including fault tolerance for network and service failures\n\nProficiency in the languages, frameworks, and API design used to expose data from a database to applications\n\nBreadth across the stack, with the greatest depth on the backend and cloud side; you don’t need to have built every layer\n\nFront-end experience building web apps that query a server and render live data is a plus\n\nExperience with telemetry from physical systems (aircraft, launch vehicles, satellites, autonomous vehicles, or connected vehicle fleets), radio links, or mission control and observability tooling is a plus\n\nPERKS & BENEFITS:\nComprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)\n\n401(k) program and transparent stock option plan\n\nSelf-managed and flexible time-off policy, including PTO, paid holidays, and sick time\n\nFlexible work environment\n\nADDITIONAL INFORMATION:\nAt Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.\nAstro Mechanica is an equal opportunity employer. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.","description_format":"text","description_chars":4425,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Flexible schedule","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Aerospace Manufacturing","Aircraft Manufacturing"],"lifecycle":[{"event":"open","at":"2026-10-29T00:42:27Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":90,"reasons":["conf:1","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/astro-mechanica-senior-ground-software-engineer","json_url":"https://alion.io/job/astro-mechanica-senior-ground-software-engineer.json","meta":{"generated_at":"2026-10-31T19:44:32Z","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":31080,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":171729},"rest":"https://alion.io/mcp/rest/get_company?id=171729"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fastro-mechanica-senior-ground-software-engineer"},{"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%2Fastro-mechanica-senior-ground-software-engineer"},{"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%2Fastro-mechanica-senior-ground-software-engineer"},{"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/astro-mechanica-senior-ground-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fastro-mechanica-senior-ground-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3431369}},{"tool":"search_jobs","arguments":{"company":"astromecha.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3431369},"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.
