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:\nYou are a software engineer who enjoys building robust engineering tools that directly impact hardware design. You thrive at the intersection of software and mechanical engineering, and you’re comfortable collaborating with structural, loads, and aero teams to translate physics into scalable, reliable code.\nYou think in systems, care deeply about performance and usability, and take pride in writing clean, well-structured Python that engineers trust for critical design decisions.\nYou’re motivated by hard technical problems-whether that’s implementing aeroelastic solution sequences, building composite stress analysis tools, or architecting databases that make complex loads data accessible and actionable.\nWHAT YOU’LL DO:\nYou will work closely with system owners across loads, flight dynamics, and structures to design and build the internal software backbone that enables multidisciplinary design optimization across the aircraft. Your tools will directly shape how we analyze, iterate, and converge on flight-ready hardware.\nDevelop and maintain Python-based stress analysis templates, including composite plate buckling, classical laminate theory (CLT), and composite failure theory implementations\n\nCreate and own a scalable loads database system that makes loads analysis data readily accessible to stress analysts and design teams\n\nImplement aeroelastic solution sequences as part of a custom-built loads analysis tool\n\nBuild reusable, well-documented libraries that enable multidisciplinary design optimization (MDO) workflows\n\nPartner closely with mechanical and aerospace engineers to translate analysis methods into production-quality software\n\nContinuously improve performance, reliability, and automation of internal engineering toolchains\n\nBuild flight dynamics simulation tools and develop interfaces for analysts across GNC, loads, and flight dynamics\n\nWHAT WE’RE LOOKING FOR:\n5+ years of experience in software engineering, development, or related field\n\nSubstantial experience in Python, including building engineering or scientific computing tools. Familiarity with Fortran is a plus\n\nBackground or familiarity in mechanical engineering, aerospace engineering, or a related technical discipline\n\nAmbition to work in a fast-paced environment\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":3806,"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":["Flexible schedule","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Aerospace Manufacturing","Aircraft Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-06T07:11:32Z"},{"event":"open","at":"2026-09-26T09:23:11Z"}],"visa":[],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.557,"p_room":0.28,"age_days":267,"expected_fill_days":90,"reasons":["conf:2","velocity","win:tail","crowd:"],"computed_at":"2026-11-08T05:47:12Z"},"pay":{"stated_usd_annual":215000,"is_top_pay":true},"html_url":"https://alion.io/job/astro-mechanica-software-engineer-engineering-applications","json_url":"https://alion.io/job/astro-mechanica-software-engineer-engineering-applications.json","meta":{"generated_at":"2026-11-08T08:45:47Z","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":18994,"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":0.02,"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-software-engineer-engineering-applications"},{"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-software-engineer-engineering-applications"},{"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-software-engineer-engineering-applications"},{"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-software-engineer-engineering-applications\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fastro-mechanica-software-engineer-engineering-applications"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":437274}},{"tool":"search_jobs","arguments":{"company":"astromecha.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":437274},"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.
