In this role, you’ll develop cutting-edge estimation and navigation technology, transforming advanced algorithms into high-performance software that powers resilient autonomy in complex, real-world environments.\nWhat you'll do:\nResearch and develop state-of-the-art state estimation and navigation algorithms to enable resilient autonomy in challenging GPS-denied environments.\nDesign and deploy production-grade C++ software for embedded robotic systems operating in dynamic, real-world environments.\nBuild and maintain rigorous unit, integration, and system-level tests to ensure system robustness and safety.\nDevelop and enhance modeling, calibration, and simulation tools for inertial and vision-based navigation systems.\nContribute to roadmap planning, feature decomposition, and agile execution alongside a multidisciplinary team of autonomy engineers.\nContinuously enhance performance analysis, benchmarking, and validation pipelines to drive rapid innovation and improvement.\nRequired qualifications:\nM.S. in Aerospace Engineering, Electrical Engineering, Robotics, Computer Science, or a related field; minimum 2+ years of related professional work experience if you have an M.S. degree, or 0 years if you are a new Ph.D. graduate.\nProfessional proficiency in modern C++ (C++11 or newer) and strong object-oriented design skills.\nHands-on experience deploying low-latency C++ applications to embedded Linux platforms.\nProfessional experience designing and implementing state estimation algorithms (e.g., EKF, UKF, Particle Filters, graph-based optimization).\nFamiliarity with VIO, SLAM, or multi-sensor fusion frameworks (e.g., GTSAM, Ceres, OpenVINS).\nStrong working knowledge of CI pipelines and automated testing frameworks for C++.\nAbility to independently deploy high-reliability code suitable for real-world autonomous systems.\nFamiliarity with prototyping in Python or MATLAB is welcome, but this role demands professional C++ production deployment skills. Candidates whose primary experience is in MATLAB or Python are unlikely to find this position a good fit.\nPreferred qualifications:\nDeep understanding of graph-based optimization for state estimation.\nExperience developing vision-aided inertial navigation systems (VINS, VIO, Terrain Relative Navigation).\nExperience with navigation sensor calibration (IMU, GPS, barometers, magnetometers, laser altimeters, cameras).\nExperience in benchmarking and system validation for real-world navigation performance.","description_format":"text","description_chars":2594,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI","Drone AI"],"lifecycle":[{"event":"open","at":"2026-09-26T21:41:58Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":132500,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":1}],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.616,"p_room":1,"age_days":18,"expected_fill_days":76,"reasons":["conf:2","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/shield-ai-staff-engineer-state-estimation-r5783","json_url":"https://alion.io/job/shield-ai-staff-engineer-state-estimation-r5783.json","meta":{"generated_at":"2026-10-15T10:04:00Z","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":15163,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":50},"rest":"https://alion.io/mcp/rest/get_company?id=50"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fshield-ai-staff-engineer-state-estimation-r5783"},{"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%2Fshield-ai-staff-engineer-state-estimation-r5783"},{"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%2Fshield-ai-staff-engineer-state-estimation-r5783"},{"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/shield-ai-staff-engineer-state-estimation-r5783\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fshield-ai-staff-engineer-state-estimation-r5783"}]}
