Our team comes from Tesla, Cruise, OpenAI, Google, Pixar, and many other great companies. In the past we've shipped to hundreds of millions of users and know what it takes to build amazing products and experiences.\nOur team is deliberately lean to promote rapid decision making and do away with bureaucracy and hierarchy. Everyone is an IC and is empowered with massive scope, radical ownership, and direct responsibility. We work across the stack with a culture built for rapid iteration and fast execution.\nWhat we look for in all candidates\nAll roles at The Bot Company demand extreme sharpness and the ability to move fast in high-intensity environments. Throughout the process, we expect candidates to demonstrate:\nExceptional mental acuity: you think quickly, learn instantly, and reason across unfamiliar domains.\n\nEngineering curiosity: you naturally dig into how systems work, even outside your specialty.\n\nHigh performance mindset: you move fast, handle ambiguity, and excel when the environment is demanding.\n\nMachine Learning: Multimodal Foundation Models\nWe are building unified foundation models that natively reason across text, image, video, and kinematics to drive intelligent robotic policies.\nYou will work on large multi-modal networks and own the entire stack from data to training and deploying models.\nWhat You'll Do\nBuild Native Multimodal Policies: Develop architectures where vision, language, and more modalities share a unified representation.\n\nImprove Cross-Modal Reasoning: Research and implement methods to ensure the model doesn't just \"associate\" modalities but actually reasons through them (e.g., grounding visual physics in kinematic constraints).\n\nOwn the Training Loop End-to-End: Design, run, debug, and iterate on large-scale training experiments; diagnosing failure modes, improving data mixtures, and tightening evaluation to drive measurable gains.\n\nShip and Iterate on Real Systems: Integrate models into real robotic stacks, build on robot code to deploy your models, and optimize performance for edge inference.\n\nRequirements\nVery strong coding skills in Python, C++, or Rust.\n\nProduction MLLM Experience: Track record of training and deploying large-scale multimodal models.\n\nPretraining & RL Mastery: Deep intuition for LLM-style pretraining, post-training, and Reinforcement Learning at scale.\n\nInfrastructure Fluency: Comfortable managing and optimizing large-scale experiments on massive GPU clusters.\n\nWhy Join\nYou’ll work with a small, elite team on challenges that require speed, intelligence, and deep engineering instinct. If you enjoy understanding systems at all levels, move fast, and think even faster, you’ll thrive here.","description_format":"text","description_chars":2827,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Domestic & Household Robotics"],"lifecycle":[{"event":"open","at":"2026-10-13T16:25:30Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.123,"p_room":0.28,"age_days":241,"expected_fill_days":23,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/the-bot-company-machine-learning-multimodal-foundation-models","json_url":"https://alion.io/job/the-bot-company-machine-learning-multimodal-foundation-models.json","meta":{"generated_at":"2026-10-25T23:19:17Z","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":32854,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":1976010},"rest":"https://alion.io/mcp/rest/get_company?id=1976010"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthe-bot-company-machine-learning-multimodal-foundation-models"},{"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%2Fthe-bot-company-machine-learning-multimodal-foundation-models"},{"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%2Fthe-bot-company-machine-learning-multimodal-foundation-models"},{"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/the-bot-company-machine-learning-multimodal-foundation-models\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthe-bot-company-machine-learning-multimodal-foundation-models"}]}
