Applied Scientist / Research Engineer, Mistral AI

• You are fluent in English, and have excellent communication skills. You are at ease explaining complex technical concepts to both technical and non-technical audiences
• You’re an expert with PyTorch or JAX
• You’re not afraid of contributing to a big codebase and can find yourself around independently with little guidance
• You write clean, readable, high-performance, fault-tolerant Python code
• You don’t need roadmaps: you just do. You don’t need a manager: you just ship
• Low-ego, collaborative and eager to learn
• You have a track record of success through personal projects, professional projects or in academia
• Proven work with time‑series modeling and transformers models applied to time-series: forecasting, anomaly/change‑point detection, irregular sampling, multivariate and hierarchical series

Desirable

• Mistral AI is seeking Applied Scientists and Research Engineers specializing in time‑series modeling to build SOTA forecasting, detection, and control systems across domains such as finance, energy, IoT, healthcare, and operations
• You will design foundation‑style temporal models and hybrids (LLM + TS), and deploy them in latency‑sensitive, reliability‑critical environments
• You’ll partner with clients to translate raw telemetry into actionable insights
• Run 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
• Pre‑train and fine‑tune time series foundational models for downstream applications in various industries
• Generate and curate data for pre-training and post-training, working on evaluations and making sure the model’s performance beats expectations
• Manage research projects and communications with client research teams
