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 are looking for a strong Machine Learning Research Engineer to join our Autonomy team and develop the learning-based algorithms that power dynamic locomotion and whole-body control on our humanoid robots.\nYou will develop robust, reusable motion capabilities that enable the robot to move dynamically, maintain balance, interact with its environment, and combine locomotion with manipulation. This includes building the underlying learning-based motion primitives that can be composed into increasingly complex whole-body behaviors.\nYou will work closely with robotics, controls, simulation, and machine learning engineers to turn learned behaviors into reliable capabilities running as part of the robot's real-time control stack.\nWhat You'll Do\nDesign and train learning-based locomotion and whole-body control policies for dynamic robotic behaviors.\n\nDevelop motion primitives using different learning based generative models.\n\nApply reinforcement learning, imitation learning, and other learning-based approaches to motion generation and control.\n\nBuild scalable simulation, data generation, and training pipelines using platforms such as Isaac Lab and MuJoCo.\n\nDevelop methods for robustness, adaptation, and sim-to-real transfer, including domain randomization and learning from real-world robot data.\n\nDeploy, evaluate, debug, and fine-tune learned policies on physical humanoid robots.\n\nOptimize policy inference and training systems for the performance and latency requirements of real-time control.\n\nIntegrate learned policies into the broader robot control and autonomy stack.\n\nWhat We're Looking For\nBS, MS, or PhD in Robotics, Machine Learning, Computer Science, or a related technical field.\n\n3+ years of experience developing machine learning systems in industry or research.\n\nStrong understanding of deep learning and modern policy architectures, including training, inference, experimentation, and debugging.\n\nHands-on experience with RL and at least one additional area such as imitation learning, generative models, sequence models, or large-scale representation learning.\n\nStrong Python and PyTorch experience.\n\nExperience with physics-based simulation environments such as Isaac Lab, Isaac Sim, MuJoCo, or similar platforms.\n\nAbility to reason about learning algorithms in the context of dynamics, control, and physical systems.\n\nNice to have:\nExperience applying reinforcement learning or imitation learning to legged robots, humanoids, or other complex physical systems.\n\nExperience with whole-body control, locomotion, motion imitation, or loco-manipulation.\n\nExperience deploying learned policies on real robotic systems and debugging the sim-to-real gap.\n\nFamiliarity with motion capture, trajectory optimization, model-based control, or learning from demonstrations.\n\nExperience training policies at scale across large numbers of simulated environments.\n\nPublications at NeurIPS, ICML, ICLR, CoRL, RSS, CVPR, or equivalent contributions to impactful open-source robotics or machine learning projects.\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":4195,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"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":"2026-10-15T13:51:29Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":0,"expected_fill_days":56,"reasons":["conf:1","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/humanoid-senior-machine-learning-research-engineer","json_url":"https://alion.io/job/humanoid-senior-machine-learning-research-engineer.json","meta":{"generated_at":"2026-10-16T17:26:44Z","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":2101,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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-senior-machine-learning-research-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%2Fhumanoid-senior-machine-learning-research-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%2Fhumanoid-senior-machine-learning-research-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/humanoid-senior-machine-learning-research-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanoid-senior-machine-learning-research-engineer"}]}
