You'll sit at the boundary between generative models and classical physics simulation, and decide where each one earns its keep.\nIt's a role at the edge of generative rollouts and physics engines, building environments and evaluation harnesses trainable at scale. It fits someone with real simulation-systems experience who's shipped tools other people used. If you want a pure-research or pure-graphics seat, this lives in the hybrid between them.\nWhat You'll Own\nDesign simulation environments that are visually rich, physically plausible, and trainable at scale - a hybrid of generative rollouts and physics-engine scenes.\n\nBuild the evaluation harness that shows whether the world model is good enough to train robots on (sim-to-real gap, physical consistency, long-horizon coherence).\n\nDevelop differentiable and GPU-accelerated simulation pipelines where they unlock new training signal.\n\nDrive the asset, scene, and task generation pipelines, including using Luma's own generative stack to bootstrap diversity.\n\nCollaborate with world-model researchers upstream and policy-learning researchers downstream.\n\nFirst 90 Days\nOne way the first 90 could unfold.\nDays 1-30 - Immerse & Diagnose: Learn the generative stack and where physics simulation and generative rollouts each fit.\n\nDays 30-60 - Ship & Validate: Build a first hybrid simulation environment and an evaluation harness for it.\n\nDays 60-90 - Scale & Systemize: Scale the asset, scene, and task pipelines and make the eval a reliable training signal.\n\nWhat You Bring\nA strong background in robotics simulation, computer graphics, physics-based modeling, or generative 3D, by degree or practical record.\n\nFluency in Python and C++, and deep familiarity with at least one production physics engine (Isaac Sim/Lab, MuJoCo, Bullet, PhysX, Drake).\n\nA track record building simulation systems other people actually used.\n\nNice to Have\nResearch on sim-to-real transfer, domain randomization, differentiable simulation, or neural-rendering-based simulation.\n\nA game engine, CGI, animation, or photogrammetry background.\n\nPublications at top venues (CoRL, RSS, ICRA, NeurIPS, SIGGRAPH).\n\nAbout Luma: Luma's mission is to build unified general intelligence that can generate, understand, and operate in the physical world. We believe multimodality is critical for intelligence - the next step beyond language models comes from vision. Luma is an equal opportunity employer.","description_format":"text","description_chars":2618,"description_truncated":false,"requirements":{"experience_years_min":null,"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":["Generative 3D","Generative Image","Generative Video"],"lifecycle":[{"event":"open","at":"2026-07-24T21:57:07Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 37","filings_12m":37,"filings_prev_12m":9,"green_card_filings_12m":0,"median_offered_wage_usd":183446,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":33}],"liveness":{"score":21,"band":"cold","label":"Long shot","p_open":1,"p_active":0.579,"p_room":0.36,"age_days":97,"expected_fill_days":58,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/luma-ai-simulation-researcherengineer","json_url":"https://alion.io/job/luma-ai-simulation-researcherengineer.json","meta":{"generated_at":"2026-10-30T20:29:23Z","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":10489,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":247},"rest":"https://alion.io/mcp/rest/get_company?id=247"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fluma-ai-simulation-researcherengineer"},{"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%2Fluma-ai-simulation-researcherengineer"},{"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%2Fluma-ai-simulation-researcherengineer"},{"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/luma-ai-simulation-researcherengineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fluma-ai-simulation-researcherengineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":35012}},{"tool":"search_jobs","arguments":{"company":"lumalabs.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":35012},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
