We partner with enterprises tackling the hardest problems across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector, co-creating customized AI systems that they can run on their terms.\nWe are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited.\nThe Role\nMistral AI is seeking Applied Scientists and Research Engineers to drive innovative research and collaborate with clients on complex research projects.\nYou will develop SOTA models across different modalities such as text, image, and speech. By developing novel methods and research ideas you will apply these models across a diverse set of use cases and domains. Working cross-functionally with both external and internal science, engineering, and product teams you will deliver high-impact AI solutions that turn the needle.\nWhat you will do\nRun pre-training, post-training and deploy state of the art models on clusters with thousands of GPUs. You don’t panic when you see OOM errors or when NCCL feels like not wanting to talk.\nGenerate and curate data for pre-training and post-training, working on evaluations and making sure the model’s performance beats expectations.\nDevelop the necessary tools and frameworks to facilitate data generation, model training, evaluation and deployment.\nCollaborate with cross-functional teams to tackle complex use cases using agents and RAG pipelines.\nManage research projects and communications with client research teams.\nWhat We're Looking For\nYou have excellent communication skills. You are at ease explaining complex technical concepts to both technical and non-technical audiences.\nYou’re an expert with PyTorch or JAX.\nYou’re not afraid of contributing to a big codebase and can find yourself around independently with little guidance.\nYou write clean, readable, high-performance, fault-tolerant Python code.\nYou don’t need roadmaps: you just do. You don’t need a manager: you just ship.\nLow-ego, collaborative and eager to learn.\nYou have a track record of success through personal projects, professional projects or in academia.\nNice to have\nHold a PhD / master in a relevant field (e.g., Mathematics, Physics, Machine Learning, Computer Science & Engineering), but if you’re an exceptional candidate from a different background, you should apply.\nCan bring a variety of research experience (agents, multi-modality, robotics, diffusion, time-series).\nHave contributed to a large codebase used by many (open source or in the industry).\nHave a track record of publications in top academic journals or conferences.\nLove improving existing code by fixing typing issues, adding tests and improving CI pipelines.\nWhat We Offer\nWe offer a comprehensive benefits package designed to support your well-being, growth, and work-life balance. Benefits vary by country and may include healthcare coverage, parental leave, retirement plans, relocation support, wellness programs, meal and transportation allowances, and other location-specific perks.\nFor the most up-to-date details on benefits available in your location, please refer to our Benefits page.\nPrivacy Policy\nYour privacy matters to us. You can learn more about how we handle your personal data in our Applicant Privacy Policy.","description_format":"text","description_chars":3612,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Parental leave","Retirement plans","Wellness"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["LLM & Generative AI","Code Intelligence","Foundation Models","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-09-25T18:39:18Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 50","filings_12m":50,"filings_prev_12m":15,"green_card_filings_12m":0,"median_offered_wage_usd":282500,"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":44}],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.595,"p_room":0.44,"age_days":74,"expected_fill_days":64,"reasons":["conf:2","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/mistral-ai-applied-scientist","json_url":"https://alion.io/job/mistral-ai-applied-scientist.json","meta":{"generated_at":"2026-10-18T11:50:29Z","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":17626,"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":22},"rest":"https://alion.io/mcp/rest/get_company?id=22"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmistral-ai-applied-scientist"},{"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%2Fmistral-ai-applied-scientist"},{"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%2Fmistral-ai-applied-scientist"},{"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/mistral-ai-applied-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmistral-ai-applied-scientist"}]}
