Today, robotics is fragmented, slow, and closed: most builders are forced to reinvent the same stack again and again, and most ideas never make it past the prototype stage. We exist to change that. Our mission is to democratize robotics by lowering the barrier to entry, delivering a plug-and-play platform for developers, researchers, and enterprises, and cultivating an open ecosystem that accelerates the evolution of physical AI.\nIf you want to help shape the next layer of human capability - and believe the future of robotics should be built together, not in isolation - we'd love to build it with you.\nThe Role\nWe are looking for a Senior Robotics Navigation Engineer to own the localization, mapping, and navigation stack for our humanoid robots. You will design and implement 3D SLAM pipelines, multi-modal state estimation systems, and real-time navigation algorithms that enable our robots to understand where they are, build accurate maps of their environment, and move through it reliably.\nThis is a production-focused role. You are not prototyping algorithms in simulation - you are deploying them on hardware, validating them in real environments, and owning their reliability at scale. We want engineers who have closed that loop before: on self-driving cars, AGVs, mobile robots, or similar deployed autonomous systems.\nResponsibilities\nDesign, implement, and deploy production-grade 3D SLAM and localization systems fusing data from LiDAR, RGB-D cameras, IMUs, wheel encoders, and proprioceptive signals\n\nBuild and maintain state estimation pipelines - Kalman Filters, Extended Kalman Filters (EKF), Unscented Kalman Filters (UKF), or Factor Graph backends (GTSAM, Ceres, g2o) - with reliable accuracy in dynamic, GPS-denied, and perceptually degraded environments\n\nDevelop real-time 3D navigation algorithms: costmap generation from point clouds, global and local path planners (sampling-based, optimization-based), and traversability analysis\n\nImplement sensor calibration pipelines (intrinsic and extrinsic) for multi-sensor rigs; own the calibration quality that underpins system accuracy\n\nDesign and build the evaluation and regression frameworks that prove the navigation stack is working correctly - logging, metrics, replay tooling, and failure analysis infrastructure\n\nCollaborate with perception, controls, and hardware teams to integrate the navigation stack end-to-end into the full robot autonomy system\n\nTroubleshoot and resolve challenging field failures; own root cause analysis and system-level fixes when localization or navigation breaks in deployment\n\nMentor junior engineers and contribute to technical roadmap planning for the autonomy stack\n\nMinimum Qualifications\n5+ years of industry experience in robotics autonomy, with a primary focus on SLAM, localization, or state estimation\n\nProven track record of deploying navigation or SLAM systems on real autonomous platforms - self-driving vehicles, AGVs, mobile robots, or equivalent - not just simulation or research prototypes\n\nDeep theoretical and practical command of probabilistic robotics: Bayesian filtering, sensor fusion, covariance modeling, and non-linear optimization\n\nHands-on experience with 3D SLAM modalities: LiDAR SLAM, Visual SLAM (VSLAM), Visual-Inertial Odometry (VIO), or multi-modal fusion\n\nProficiency in C++ (C++14/17 or newer) for real-time, performance-critical code; strong software engineering fundamentals\n\nExperience with optimization libraries: GTSAM, Ceres Solver, g2o, or equivalent factor graph backends\n\nFamiliarity with ROS/ROS 2 and standard robotics tooling\n\nAbility to explain why a localization module failed in a specific scenario to both a technical peer and a non-technical stakeholder\n\nPreferred Qualifications\nM.S. or Ph.D. in Robotics, Computer Science, Electrical Engineering, or related field\n\nExperience with learning-based or hybrid approaches to localization and mapping (e.g., neural implicit maps, foundation model-assisted SLAM)\n\nBackground in semantic SLAM or scene understanding - associating geometric maps with object-level semantics\n\nExperience with GPU acceleration (CUDA) for perception or navigation pipelines\n\nGNSS/RTK fusion experience for outdoor or GPS-blended deployments\n\nFamiliarity with map management at scale: map storage, versioning, sharing across a robot fleet, and lifecycle management\n\nPrior experience in a startup or fast-moving R&D environment with an emphasis on shipping\n\nContributions to open-source SLAM or navigation frameworks (ORB-SLAM, RTAB-Map, Cartographer, LIO-SAM, KISS-ICP, etc.)","description_format":"text","description_chars":4755,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-01-19T15:44:39Z"}],"visa":[],"liveness":{"score":27,"band":"fade","label":"Fading","p_open":1,"p_active":0.755,"p_room":0.36,"age_days":270,"expected_fill_days":169,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/dexmate-senior-robotics-navigation-engineer","json_url":"https://alion.io/job/dexmate-senior-robotics-navigation-engineer.json","meta":{"generated_at":"2026-10-18T04:27:48Z","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":6647,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":6958},"rest":"https://alion.io/mcp/rest/get_company?id=6958"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdexmate-senior-robotics-navigation-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%2Fdexmate-senior-robotics-navigation-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%2Fdexmate-senior-robotics-navigation-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/dexmate-senior-robotics-navigation-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdexmate-senior-robotics-navigation-engineer"}]}
