About The Job

Mistral AI is looking for Applied Scientists with deep expertise in engineering sciences to work at the frontier of AI-accelerated simulation. You will work with industrial customers and internal research teams to build and deploy AI Physics Models alongside our existing offerings of Large Language Models (LLMs).

You will contribute across the full stack: curating high-fidelity simulation datasets, training and evaluating models, and delivering production-grade AI solutions directly to engineering teams. Target domains include computational fluid dynamics, structural mechanics, semiconductor design, multi-physics modelling, and digital twins.

Working cross-functionally with research, product, and customer-facing teams, you will ensure our models meet real engineering standards — not just benchmark metrics.

What you will do

• Design and run large-scale simulation campaigns using domain-specific solvers (e.g. OpenFOAM, ANSYS, COMSOL, Abaqus)

• Run training of AI models on physics data, with rigorous evaluation of coverage, accuracy, and quality against industry validation standards

• Build tools and frameworks for automated dataset creation, simulation pipeline management, and model evaluation

• Develop agents and RAG that integrate LLMs with engineering simulation workflows

• Collaborate closely with the collaborate with the science/research team on training runs and diagnose failure modes arising from data gaps or architecture limitations

• Manage research projects and client communications with engineering teams

About you

• Fluent English with excellent communication skills - able to explain technical simulation concepts to both engineering and non-technical audiences

• PhD or Master's in AI or an engineering science: Mechanical Engineering, Electrical Engineering, Computational Fluid Dynamics, Structural Mechanics, Semiconductor Engineering, or a related field. A solid understanding of deep learning and engineering or physics is a must.

• Comfortable wi
