serial, shared-memory (e.g. OpenMP), or message-passing (e.g. MPI) -appropriate to workload scale.\nState Estimation: Implement Kalman-filter-based state estimation that fuses multiple sensor measurements - prediction, innovation, Jacobian assembly, and correction.\nRequirements\nMandatory:\nC++ (modern, 11/14/17+)\nAdaptive-step ODE/numerical integration, linear algebra\nMulti-threading (std::thread, thread pools), race-condition/false-sharing avoidance\nManual memory management, leak-free integration with third-party C/C++ libraries\nQuaternion/rotation math, coordinate frame transforms\nCMake, unit testing (GoogleTest or similar)\nPython (for tooling/scripting/testing)\nKalman/Bayesian filtering theory\nAttitude/rigid-body dynamics background\nAstrodynamics / orbital mechanics fundamentals\nTLE (Two-Line Element) format familiarity\nOptional:\nOpenMP, MPI/OpenMPI\nValgrind, AddressSanitizer, profilers (perf, VTune)\nCI pipelines for C++, cross-platform builds\nBenefits\nWe offer great career growth, ESOPs, Gratuity, PF and Health Insurance.","description_format":"text","description_chars":1757,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Satellite Communications","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-11T22:36:30Z"}],"visa":[],"liveness":{"score":45,"band":"ok","label":"Likely open","p_open":1,"p_active":0.744,"p_room":0.6,"age_days":93,"expected_fill_days":111,"reasons":["conf:2","win:late","crowd:"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/astrome-space-simulation-engineer","json_url":"https://alion.io/job/astrome-space-simulation-engineer.json","meta":{"generated_at":"2026-11-07T23:10:39Z","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":38495,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":669544},"rest":"https://alion.io/mcp/rest/get_company?id=669544"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fastrome-space-simulation-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%2Fastrome-space-simulation-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%2Fastrome-space-simulation-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/astrome-space-simulation-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fastrome-space-simulation-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":774779}},{"tool":"search_jobs","arguments":{"company":"astrome.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":774779},"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.
