Mistral AI is looking for an Applied Scientist to join its Solutions department in Palo Alto with remote flexibility. This full-time opportunity suits an autonomous AI professional with expertise in PyTorch, Python, and RAG who wants to build state-of-the-art models for enterprise clients.

Role Overview

Mistral AI is hiring Applied Scientists and Research Engineers to lead innovative research and partner with clients on advanced technical projects. Professionals in this position build cutting-edge models across speech, image, and text modalities. By creating novel research concepts, team members apply these models to various domains and use cases. The role requires close cross-functional collaboration with internal and external product, engineering, and science groups to deliver high-impact artificial intelligence systems.

Key Responsibilities

Execute pre-training, post-training, and deployment of state-of-the-art models on large clusters containing thousands of GPUs while troubleshooting technical errors.
Curate and generate datasets for training phases, conduct rigorous evaluations, and ensure model performance exceeds expectations.
Build internal tools and frameworks that streamline data generation, model training, evaluation, and deployment processes.
Partner with cross-functional groups to solve intricate use cases utilizing agents and RAG pipelines.
Lead research initiatives and manage ongoing communications with client research teams.

Requirements

Possess exceptional communication skills with the ability to explain complex technical ideas to technical and non-technical stakeholders.
Demonstrate expert-level proficiency in PyTorch or JAX.
Capable of navigating large codebases independently with minimal supervision and guidance.
