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 have experience in one of the following: VLMs, diffusion for image/video, audio processing (ASR/TTS), image processing, robotics
• 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

Desirable

• Mistral AI is seeking Applied Scientists and Research Engineers focused on multimodal learning (text, image, audio, video) to drive innovative research and collaborate with clients on complex projects
• You will design, train, and deploy SOTA multimodal models (e.g. , Omni-models, VLMs, Audio, Image generation, Robotics and much more) and apply them to diverse use cases: enterprise search, agents grounded in images and documents, video understanding, and speech interfaces
• You’ll work cross‑functionally with internal and external science, engineering, and product teams to deliver high‑impact AI solutions
• 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
• Generate and curate multimodal datasets (web‑scale image‑text, document‑image, audio‑text, video‑text), and build robust evaluators/benchmarks for perception, grounding, OCR, and captioning
• Develop the necessary tools and frameworks to facilitate data generation, model training, evaluation and deployment
• Collaborate with cross-functional teams to tackle complex use cases using agents and RAG pipelines
• Manage research projects and communications with client research teams
