The goal of the company is to ship humanoid robots with human level intelligence. Its robots are engineered to perform a variety of tasks in the home and commercial markets. Figure is headquartered in San Jose, CA.\nWe are looking for a State Estimation Engineer to own the architecture, algorithm development, and calibration workflows for a next-generation data collection system. This system powers two core capabilities: low-latency real-time teleoperation of our humanoid robots and ultra-high-precision offline trajectory reconstruction for data collection and policy training. You will build and deploy dual-tier estimation pipelines and user-onboarding calibration routines that fuse heterogeneous sensor modalities to track full-body human kinematics and floating-base motion across dynamic tasks.\nResponsibilities:\nDesign and implement dual-tier state estimation algorithms in modern C++: low-latency, real-time filters for streaming teleoperation and batch optimization/smoothing routines for high-accuracy offline dataset generation.\n\nOwn and develop subject-calibration procedures, designing rapid, intuitive routines to estimate individual body segment dimensions, joint offsets, and sensor-to-body extrinsics whenever a user equips the system.\n\nDevelop robust sensor fusion architectures combining spatial transforms, visual-inertial data, and inertial signals into full-body kinematic pose estimates.\n\nAddress spatiotemporal sensor calibration, dynamic environmental interference, and kinematic constraint enforcement on human skeletal models.\n\nDevelop techniques to extract useful information from compliant tactile sensing in the presence of large sensor deformation, stretching or folding.\n\nDiagnose and understand limitations of existing hardware or designs and inform future design requirements.\n\nEvaluate novel sensing modalities to inform future hardware designs.\n\nBuild diagnostic tooling, validation pipelines, and error analysis workflows to evaluate accuracy for both online and offline algorithms.\n\nRequirements:\n4+ years of experience building multi-sensor fusion and state estimation solutions for dynamic hardware systems.\n\nHands-on expertise with both real-time filtering techniques ((E)KFs, sliding-window estimators) and offline batch optimization tools (Factor Graphs, GTSAM, Ceres, Non-Linear Least Squares).\n\nProven capability to design fast, reliable calibration, zeroing, and alignment workflows for multi-sensor suites and kinematic models.\n\nDeep mathematical foundation in 3D spatial kinematics, Lie groups (SE(3), SO(3)), forward/inverse kinematics, and constrained optimization.\n\nProven ability to write high-performance, modular C++ for embedded or edge computing platforms alongside Python for data analysis and visualization.\n\nBonus Qualifications:\nExperience with low-latency streaming pipelines for teleoperation, haptics, or human-in-the-loop control systems.\n\nBackground in human biomechanics, skeletal tracking, or body-mounted telemetry systems.\n\nPrior experience applying Machine Learning (ML) techniques to motion priors, trajectory smoothing, or learned state estimation/calibration.\n\nThe US base salary range for this full-time position is $150,000 to $300,000 per year.\nThe pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.","description_format":"text","description_chars":3629,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Humanoid Robots","Multimodal AI"],"lifecycle":[{"event":"open","at":"2026-08-18T18:13:10Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 23","filings_12m":23,"filings_prev_12m":23,"green_card_filings_12m":0,"median_offered_wage_usd":227500,"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":7}],"liveness":{"score":88,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.875,"p_room":1,"age_days":62,"expected_fill_days":179,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-20T05:45:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/figure-ai-state-estimation-engineer-data-collection-systems","json_url":"https://alion.io/job/figure-ai-state-estimation-engineer-data-collection-systems.json","meta":{"generated_at":"2026-10-20T15:50:51Z","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":17985,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":25},"rest":"https://alion.io/mcp/rest/get_company?id=25"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffigure-ai-state-estimation-engineer-data-collection-systems"},{"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%2Ffigure-ai-state-estimation-engineer-data-collection-systems"},{"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%2Ffigure-ai-state-estimation-engineer-data-collection-systems"},{"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/figure-ai-state-estimation-engineer-data-collection-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffigure-ai-state-estimation-engineer-data-collection-systems"}]}
