INTERNSHIP - CFD/AI Engineer

At SIMULIA our mission is to provide best-in-class simulation technologies integrated into the 3DXPERIENCE platform in the most efficient way possible. In the Fluids group, we have a world-class group of researchers who develop fluids solver capabilities. SIMULIA software simulation products impact how Computational Fluid Dynamics (CFD) is used in many industrial settings worldwide.

We are looking for a CFD engineer with ML/AI skills who can work on an intelligent meshing project for our Navier-Stokes and Lattice-Boltzmann technology.

As a CFD/AI engineer, you will be part of a key team in building and executing numerical DoEs and supporting the development of AI/ML technologies and their integration into commercial CFD software. As part of this internship, you will gain experience automating and executing simulations and working with AI/ML tools and software in a production environment. We will provide you with the steps, tools, and leadership that will help advance your career at Dassault Systemes and help our customers reach their goals.

• Perform industrially-relevant CFD simulations
• Generate large datasets of high-quality CFD data
• Build, develop, and train ML algorithms for intelligent meshing
• Interact with multiple teams and across disciplines to report results and enhance model capabilities

• Enrolled in a PhD program in Mechanical or Aerospace engineering or a related field
• Experience performing CFD simulations
• Experience with Navier-Stokes algorithms including RANS turbulence models
• Experience with finite volume meshing
• Experience with ML algorithms including geometric deep learning, transformers, and neural operators
• Proficient in Python
• Familiarity with UNIX/Linux and shell scripting a plus
• Fluency in English, both written and verbal is essential
• Ability to work independently

This is a paid six-month internship/co-op to begin in spring 2026. The position is based at the Dassault Systemes Office at 175 Wyman Street, Waltham, MA.
