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.\nAbout The Job\nMistral AI is seeking Applied Scientists and Research Engineers focused on time series. You will design, train, and deploy state-of-the-art time-series foundation models, and apply them to the most demanding forecasting problems in industry, from power grids and plants to trading desks.\nTimestral, our family of time-series foundation models, ranked first on amongst all benchmarks at release (tech report). The role has two sides: building the next generations of Timestral with our Science team, and taking them into production with our industrial and financial clients, adapted to their data. Working cross-functionally with both external and internal science, engineering, and product teams you will deliver high-impact AI solutions. We are made of researchers, engineers, product builders, ex-founders who love tackling the most complex real world problems in the industry.\nWhat you will do\nRun pre-training, post-training and deploy state of the art time-series foundation models on clusters with thousands of GPUs.\n\nGenerate and curate large-scale time-series datasets, real and synthetic, and build evaluators and benchmarks for forecasting and other time-series tasks.\n\nPush the frontier of Timestral: architectures, training recipes, scaling, and new capabilities such as anomaly detection, classification and embeddings.\n\nFine-tune and adapt Timestral on client data, in the cloud or on-premise, and benchmark it against the client's existing models.\n\nDevelop the necessary tools and frameworks to facilitate data generation, model training, evaluation and deployment.\n\nCollaborate with cross-functional teams to tackle complex use cases, including agents that combine Timestral with Mistral LLMs.\n\nManage research projects and communications with client research teams.\n\nAbout you\nFluent in English with excellent communication skills, at ease explaining complex technical concepts to both technical and non-technical audiences.\n\nExpert with PyTorch or JAX.\n\nSolid knowledge of modern deep learning and large language models: architectures, pre-training, post-training and evaluation.\n\nExperience pre-training or fine-tuning time-series foundation models or large transformer models at scale.\n\nStrong background in time-series modelling: probabilistic forecasting, multivariate series and covariates, and classical baselines (statistical models, gradient boosting).\n\nNot afraid of contributing to a big codebase; finds their way around independently with little guidance.\n\nWrites clean, readable, high-performance, fault-tolerant Python code.\n\nDoesn't need roadmaps: moves independently and is comfortable with uncertainty.\n\nLow-ego, collaborative and eager to learn.\n\nTrack record of success through personal projects, professional projects or academia.\n\nNice to have\nEx-founder or builder\n\nPhD / Master in a relevant field (Machine Learning, Statistics, Applied Mathematics, Physics). Exceptional candidates from other backgrounds welcome.\n\nResearch on time-series foundation models: pre-training, scaling, synthetic data or evaluation.\n\nHands-on experience training or fine-tuning LLMs, building agents and tool use, or models that combine text and time series.\n\nIndustry experience in energy, industrial operations, telecom or finance, or experience deploying models for industrial clients.\n\nExperience working on large code bases or large machine learning models at scale.\n\nContributions to a large open-source or industry codebase.\n\nPublications in top academic journals or conferences.\n\nEnjoys improving existing code: typing, tests, CI pipelines.\n\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.
