a PhD or postgraduate research experience in computational methods is a plus.\nStrong programming skills in C++ and/or modern Fortran, with Python for scripting, tooling, and automation.\nSolid understanding of numerical methods such as finite volume, finite element, or finite difference, including discretisation schemes, solvers, and stability.\nExperience with computational fluid dynamics (CFD), heat transfer, or structural codes, whether in-house or open source (e.g. OpenFOAM, SU2).\nExperience with parallel computing and performance optimisation in Linux/HPC environments.\nComfortable working autonomously in fast-moving, prototype-heavy environments, with a focus on code quality, correctness, and maintainability.\nWhat we offer\nA mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.\nDaily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow.\nHigh ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.\nA fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions.\nA culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.\nCompetitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.\nSecurity and Eligibility Requirement\nDue to the nature of the work we undertake, applicants must be a EU/Nato/German citizen, and be eligible for German Security Clearance.","description_format":"text","description_chars":3156,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[{"language":"German","level":"All levels","optional":false}]},"benefits":["Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Missiles"],"lifecycle":[{"event":"open","at":"2026-10-29T14:54:44Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":26,"expected_fill_days":125,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/hypersonica-numerical-code-developer","json_url":"https://alion.io/job/hypersonica-numerical-code-developer.json","meta":{"generated_at":"2026-11-02T14:20:55Z","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":19842,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":678356},"rest":"https://alion.io/mcp/rest/get_company?id=678356"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhypersonica-numerical-code-developer"},{"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%2Fhypersonica-numerical-code-developer"},{"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%2Fhypersonica-numerical-code-developer"},{"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/hypersonica-numerical-code-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhypersonica-numerical-code-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3464143}},{"tool":"search_jobs","arguments":{"company":"hypersonica.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3464143},"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);
