contact model parameterisation, actuator model calibration\n\nReal-time state estimation: floating-base EKF/UKF implementation and tuning for pelvis pose, velocity, and foot contact state at RT loop rates; feeds downstream controllers and loco-manipulation policy inputs\n\nSim-to-real pipeline: parameter estimation loops, hardware-data-driven calibration, validation against motion capture or external reference systems - the continuous feedback loop between hardware campaigns and updated sim models\n\nFailure mode ownership: debugging model-accuracy-driven failures - control instability from inaccurate dynamics, estimation drift or bias causing divergence, incorrect contact/force estimation leading to instability in dynamic interactions\n\nCross-team interface: supplying updated Pinocchio model parameters to the WBC and State Estimation Engineers in Core Robot Software; aligning on excitation trajectory designs with the Locomotion and RL/Control Engineers\n\nWhat we can look forward to\nMSc or PhD in Robotics, Mechanical Engineering, Electrical Engineering, or a related field with a strong foundation in dynamics, estimation, and control\n\n4+ years of experience developing state estimation or system identification solutions for real-time robotic systems - on real hardware, not simulation-only\n\nSystem identification on physical robotic systems: excitation trajectory design, least-squares or maximum-likelihood regressor fitting, actuator and transmission parameter identification\n\nState estimation implementation: EKF or UKF for floating-base pose, velocity, and contact state on a legged or mobile robot platform\n\nRigid body dynamics depth: contact modelling, actuator behaviour, and how model inaccuracies propagate to control instability - not just theoretical familiarity\n\nExperience supporting control systems (MPC, WBC) or learned policies (RL) through hardware deployment - understanding how model quality gates policy transfer\n\nC++ for production RT systems; Python for analysis, tooling, and calibration pipelines\n\nNice to Have\nHumanoid or legged robot hands-on experience - 4NE1 is a full-size humanoid; bipedal dynamics and contact complexity are directly relevant\n\nDifferentiable simulators for gradient-based system identification (Brax, DiffTaichi, or comparable)\n\nSim-to-real transfer methodology: domain randomisation, adaptive calibration, residual physics modelling\n\nPinocchio for rigid-body model computation and parameter sensitivity analysis\n\nMuJoCo model authoring: MJCF contact parameters, actuator models, tendon dynamics\n\nFactor graph-based estimation (GTSAM, iSAM2) for tightly-coupled IMU + kinematics fusion\n\nPublications or open-source contributions in legged robot dynamics, system identification, or sim-to-real transfer","description_format":"text","description_chars":3333,"description_truncated":false,"requirements":{"experience_years_min":4,"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","Collaborative Robots (Cobots)","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-10-13T02:53:41Z"}],"visa":[],"liveness":{"score":23,"band":"cold","label":"Long shot","p_open":1,"p_active":0.652,"p_room":0.36,"age_days":141,"expected_fill_days":85,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/neura-robotics-dynamics-system-identification-estimation-engineer-pla-human","json_url":"https://alion.io/job/neura-robotics-dynamics-system-identification-estimation-engineer-pla-human.json","meta":{"generated_at":"2026-10-21T17:45:35Z","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":25092,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":48149},"rest":"https://alion.io/mcp/rest/get_company?id=48149"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fneura-robotics-dynamics-system-identification-estimation-engineer-pla-human"},{"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%2Fneura-robotics-dynamics-system-identification-estimation-engineer-pla-human"},{"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%2Fneura-robotics-dynamics-system-identification-estimation-engineer-pla-human"},{"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/neura-robotics-dynamics-system-identification-estimation-engineer-pla-human\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fneura-robotics-dynamics-system-identification-estimation-engineer-pla-human"}]}
