Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We’re building the foundation behind the foundation models - the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain - to help our partners drive the field forward.\nThe Perception Algorithm team transforms raw multimodal sensor data into high-quality robot training annotations. You will be deeply involved in the complete loop from data collection to model delivery - sensor calibration, SLAM localization, human pose estimation, perception model training, and embedded deployment. Your work directly determines the quality ceiling of our training data.\nCore Responsibilities\nHuman Pose Estimation\nDesign and optimize hand pose estimation pipelines supporting accurate joint angle extraction from teleoperation data collection\n\nBuild full-body pose estimation systems for motion capture and teleoperation action annotation ground truth generation\n\nResearch and apply vision-based pose estimation methods (markerless) to reduce data collection costs\n\nRetargeting pose estimation outputs with robot joint angle data to generate consistent training annotations\n\nRobot Perception & Calibration\nDesign and maintain intrinsic/extrinsic calibration pipelines for multi-camera arrays (factory calibration + online recalibration)\n\nBuild visual SLAM / V-SLAM systems supporting real-time localization and scene reconstruction on data collection platforms\n\nImplement hand-eye calibration between cameras and robot end-effectors\n\nDevelop temporal alignment solutions across multimodal sensors (cameras, IMU, data gloves, force sensors)\n\nPerception Model Training & Deployment\nTrain and iterate on perception models including object detection, instance segmentation, and 6DoF pose estimation\n\nOptimize model inference using TensorRT / CUDA for real-time performance on robot embedded platforms\n\nWrite custom CUDA kernels for low-level acceleration of perception tasks\n\nDesign evaluation metric frameworks for perception models; continuously track the relationship between model performance and data quality\n\nEnd-to-End Loop from Data Collection to Model Delivery\nContribute to the design of automated annotation pipelines that convert sensor data into structured training labels\n\nBuild Auto QA modules to filter low-quality data including anomalous frames, failed demonstrations, and sensor dropouts\n\nCollaborate with ML engineers and data infrastructure teams to ensure perception output formats meet downstream VLA model training requirements\n\nEstablish feedback mechanisms linking perception accuracy to model training outcomes, continuously improving annotation quality\n\nRequirements\nMust-Have\n5+ years of industry experience in robot perception or computer vision\n\nStrong 3D vision fundamentals: stereo and structured-light camera principles, 3D reconstruction\n\nProficiency with SLAM frameworks (ORB-SLAM, VINS-Mono, FastLIO, etc.) or V-SLAM system development experience\n\nHands-on engineering experience with human pose estimation: hand joints (MediaPipe, MANO) or full-body pose (OpenPose, SMPLify, etc.)\n\nProficient in deep learning training frameworks for perception model training, tuning, and evaluation\n\nTensorRT deployment experience with real-time inference optimization on embedded platforms (Jetson, Horizon, etc.)\n\nCUDA programming fundamentals; ability to write or debug custom kernels\n\nProficient in C++ and Python with ROS / ROS2 development experience\n\nProficient with AI coding agents\n\nNice to Have\nEngineering experience with 6DoF object pose estimation (FoundPose, FoundationPose, GDR-Net, etc.)\n\nFamiliarity with 3D Gaussian Splatting or NeRF for scene reconstruction or data augmentation\n\nExperience with robot manipulation or teleoperation systems\n\nEnd-to-end development experience with automated annotation pipelines or ground truth generation systems\n\nPublished research in perception, pose estimation, or robotics\n\nWhat We Offer\nDirect involvement in the most critical technical challenge in embodied intelligence: producing high-quality robot training data\n\nAn environment working alongside top-tier robotics engineers and ML researchers\n\nProprietary hardware platforms (humanoid robots, camera arrays, data gloves)\n\nA fast-paced, high-autonomy 0→1 work environment","description_format":"text","description_chars":4382,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","AI Training Data & Annotation"],"lifecycle":[{"event":"open","at":"2026-09-11T10:41:34Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 4","filings_12m":4,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":182500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.254,"p_room":0.28,"age_days":121,"expected_fill_days":36,"reasons":["conf:1","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/xdof-senior-perception-engineer","json_url":"https://alion.io/job/xdof-senior-perception-engineer.json","meta":{"generated_at":"2026-10-18T09:19:19Z","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":13889,"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":686707},"rest":"https://alion.io/mcp/rest/get_company?id=686707"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxdof-senior-perception-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%2Fxdof-senior-perception-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%2Fxdof-senior-perception-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/xdof-senior-perception-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxdof-senior-perception-engineer"}]}
