That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND-01 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further.\nAbout The Role\nWe're hiring a Senior Simulation Engineer to join our VLA team based in London.\nIn this role, you will build and maintain simulation environments for dexterous manipulation tasks across industrial, service, and home domains. This is primarily a simulation and reinforcement learning-focused role, so we are looking for experience creating realistic physics-based environments and training RL policies, while experience in robotics isn't strictly required. However, if you don't have such experience, be prepared that you'd need to familiarize yourself with a new domain quickly.\nWhat You’ll Do\nDesign and implement gym environments for manipulation tasks spanning industrial, service, and home settings, defining appropriate observation spaces, action spaces, and reward functions.\n\nAnalyze and address reward hacking - identify cases where learned policies exploit reward misspecification and iterate on reward design to produce robust behaviors.\n\nAnalyze and reduce the sim-to-real gap by tuning physics parameters, improving asset fidelity, and validating simulation behavior against real-world data.\n\nWork with third-party vendors to procure, validate, and integrate high-quality 3D assets (objects, fixtures, environments) suitable for physics-based simulation.\n\nEnsure correct physics setup - contact dynamics, friction, mass properties, joint limits - so that trained policies transfer reliably to hardware.\n\nIdentify and reduce simulation bottlenecks to maximize training throughput and environment step rates.\n\nImprove our simulation-based evaluation and reinforcement learning infrastructure to support rapid iteration and scaling.\n\nWhat We're Looking For\n3+ years building simulation environments or game-engine-based interactive systems (industry or research) with shipped products, published results, or equivalent artifacts to show for it.\n\nDeep hands-on experience with at least one physics simulator (Isaac Sim/IsaacLab, MuJoCo, PyBullet, Drake) or equivalent game engine experience (Unreal, Unity) with a focus on physically accurate interactions.\n\nStrong practical experience running large-scale parallel simulation on GPU clusters and good familiarity with modern GPU-accelerated simulation infrastructure.\n\nStrong Python; you can profile bottlenecks, debug physics issues, and write maintainable research code.\n\nFamiliarity with modern software engineering practices.\n\nYou document experiments clearly and communicate trade-offs crisply.\n\nNice to have: \nRobotics or manipulation-specific experience (grasping, contact-rich tasks, deformable objects).\n\nExperience designing reward functions and training RL policies in simulated environments; solid understanding of common failure modes (reward hacking, distribution shift, sim-to-real gap).\n\nExperience with NVIDIA Isaac Sim & IsaacLab specifically.\n\nExperience with domain randomization, system identification, or other sim-to-real transfer techniques.\n\nPublications at top-tier robotics or RL conferences or equivalent open-source contributions.\n\nFamiliarity with robocasa, robosuite or similar open-source manipulation simulation frameworks.\n\nWhat We Offer\nCompetitive equity: stock options with meaningful upside as we scale.\n\n30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas-New Year shutdown).\n\nPrivate healthcare, including virtual and in-person care.\n\nPension scheme with 8% total contribution (5% employee, 3% employer) on full earnings.\n\nFree daily breakfast, catered lunch, and snacks in-office.\n\nWork at the frontier - collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics.\n\nReal ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one.","description_format":"text","description_chars":4279,"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":["Annual leave","Equity","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Logistics & Warehouse Robotics","Industrial Robotics","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-09-01T15:15:09Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.244,"p_room":0.28,"age_days":182,"expected_fill_days":58,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/humanoid-simulation-engineer-manipulation","json_url":"https://alion.io/job/humanoid-simulation-engineer-manipulation.json","meta":{"generated_at":"2026-10-18T13:10:55Z","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":19592,"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":35230},"rest":"https://alion.io/mcp/rest/get_company?id=35230"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhumanoid-simulation-engineer-manipulation"},{"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%2Fhumanoid-simulation-engineer-manipulation"},{"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%2Fhumanoid-simulation-engineer-manipulation"},{"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/humanoid-simulation-engineer-manipulation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanoid-simulation-engineer-manipulation"}]}
