About The Job Mistral AI is looking for Applied Scientists with deep domain and industrial expertise in physics and 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. You will contribute across the full stack: leveraging your deep domain expertise to understand complex problems that will be tackled with frontier AI, 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
Collaborate closely 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
Have a PhD in physics or engineering and 5 years+ of industry experience in a relevant domain. You work in a key engineering industry: Automotive, Aerospace or Semiconductors and have an interest in machine learning
Self‑directed – you don't need detailed roadmaps to make progress
Low‑ego, collaborative, and eager to learn at the intersection of simulation and ML
Demonstrated success through industrial projects, academic work, or personal projects
It would be great if you
Have a deep passion for machine learning
Have industrial or academic experience with simulation solvers (e.g. OpenFOAM, ANSYS, COMSOL, Abaqus, or equivalent)
Have applied ML methods to simulation or surrogate modelling
Have experience automating large‑scale simulation campaigns on HPC clusters
Have contributed to a large open‑source or industry codebase
Have publications in engineering or ML venues (NeurIPS, ICLR, etc.)
Love improving existing code by fixing typing issues, adding tests and improving CI pipelines
Benefits Locations Munich, Paris, London, Amsterdam, Lausanne, Linz. Hybrid work model.
