You'll build the digital twin environments, sim assets, and CI/CD pipelines that our autonomy team relies on daily. You will help achieve the vision in which every robot behavior we develop is prototyped, tested, and validated in simulation before it runs on hardware.\nAs a simulation engineer at Persona, you will have an incredible opportunity to shape the simulation infrastructure that underpins our entire autonomy stack. You will report to the Behavior Coordination Lead and work closely with machine learning, locomotion, manipulation, perception, and devops teams.\nYour Role:\nBuild, maintain, and extend simulation environments in NVIDIA Isaac Sim and Omniverse for humanoid robot development.\n\nDevelop and manage OpenUSD sim assets: robot models, tools, workpieces, customer facility environments (shipyards, steel fabrication plants, industrial sites).\n\nCreate and maintain physics-accurate digital twins of customer facilities (shipyards and industrial manufacturing) for behavior validation and deployment planning.\n\nIntegrate all autonomy subsystems (locomotion, manipulation, perception, hands, navigation, welding) to run against Isaac Sim.\n\nDesign and implement behavior-level CI/CD pipelines that automatically validate robot behaviors in simulation.\n\nPrototype and mock-test robot behaviors (welding, navigation, manipulation) in simulation before hardware integration.\n\nDevelop synthetic data generation pipelines for training perception, manipulation, and navigation models.\n\nWe're Looking For:\nBS, MS, or PhD in Robotics, Computer Science, Mechanical Engineering, or a related field.\n\n3+ years of professional experience in robotics simulation, digital twin development, or physics-based simulation environments.\n\nStrong hands-on experience with NVIDIA Isaac Sim and/or NVIDIA Omniverse.\n\nWorking knowledge of OpenUSD (Universal Scene Description): authoring, composition, referencing, flattening, and debugging USD stage hierarchies.\n\nProficiency in Python; comfortable writing simulation tooling, test harnesses, and automation scripts.\n\nExperience with at least one physics engine: PhysX, MuJoCo, Bullet, or Drake.\n\nSolid understanding of robot kinematics, dynamics, and articulated body simulation.\n\nExperience developing or maintaining CI/CD pipelines for simulation or robotics software.\n\nFamiliarity with containerization (Docker) and DevOps practices for simulation infrastructure.\n\nAbility to create and manage 3D simulation assets (meshes, materials, collision geometry, articulation definitions).\n\nPreferred or Bonus Qualifications:\nExperience with NVIDIA Isaac Lab for reinforcement learning environment setup and training.\n\nFamiliarity with NVIDIA Cosmos for synthetic data generation and scene variability.\n\nExperience with ROS/ROS 2 and Gazebo simulation.\n\nExperience with Unreal Engine or other real-time rendering engines for robotics visualization.\n\nBackground in manipulation simulation: contact modeling, grasp planning, dexterous multi-fingered hand interaction, and force/torque estimation.\n\nExperience with motion capture data pipelines and motion retargeting to robot models.\n\nExposure to behavior trees, task planning, or autonomy stack architecture.\n\nKnowledge of Omniverse extensions development and Kit SDK.","description_format":"text","description_chars":3376,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Industrial Robotics","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-08-30T14:04:30Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":172500,"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":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.314,"p_room":0.28,"age_days":191,"expected_fill_days":28,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/persona-ai-robotics-simulation-engineer","json_url":"https://alion.io/job/persona-ai-robotics-simulation-engineer.json","meta":{"generated_at":"2026-10-17T05:44:57Z","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":7762,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":63117},"rest":"https://alion.io/mcp/rest/get_company?id=63117"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpersona-ai-robotics-simulation-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%2Fpersona-ai-robotics-simulation-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%2Fpersona-ai-robotics-simulation-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/persona-ai-robotics-simulation-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpersona-ai-robotics-simulation-engineer"}]}
