AI Scientist - Agentic Engineering

MistralAmsterdamOn-siteFull-time19 Aug 2026

Mistral is seeking an AI Scientist with deep machine learning expertise and hands-on CAD experience to join the AI4Engineering Science team in Amsterdam. The role focuses on building pre- and post-training data, verifiers, and agent architectures to teach frontier LLMs to generate, analyze, and modify CAD designs. Requires strong LLM development background and demonstrated CAD workflow automation experience.

What you'll do

Design pretraining, SFT, and RL data for CAD tasks: text-to-CAD and image-to-CAD generation from technical drawings, geometric analysis and QA of CAD parts, and design modification
Define verifiers and evaluation criteria that capture what "correct" and "high-quality" actually mean for CAD tasks
Scale the data pipelines that produce agentic CAD training traces
Design and improve agent architectures and harnesses: how models plan, call CAD tools via API or computer use, recover from errors, and chain steps together across long-horizon design workflows
Build and maintain CAD evaluation benchmarks and diagnostic tooling, from parametric CAD and drawing-to-3D benchmarks to industrial evaluations, identifying where models fail and tracing those failures back to gaps in data, reward design, or agent scaffolding
Collaborate with CAD domain experts and the CAE and EDA streams (and the science and solutions teams more broadly) to identify which CAD workflows are highest-value to target next
Contribute to Mistral's broader pre- and post-training research, sharing findings and methodology across the science organization
