What you would do

Our Dassault Systemes SIMULIA brand provides best-in-class simulation technologies integrated into the 3DEXPERIENCE platform in the most effective way possible. The Fluids group in SIMULIA consists of a world-class group of experts who develop the next generation of fluids solver capabilities. As part of SIMULIA software simulation products, these innovations impact how Computational Fluid Dynamics (CFD) is used in many industrial settings worldwide.

We are looking for a CFD engineer with AI experience who can test and validate our AI-infused fluids technology. This is a paid six month internship/co-op. The position is based at the Dassault Systemes Office at 175 Wyman Street, Waltham, MA.

We are developing the next generation of Computational Fluid Dynamics technologies spanning advanced numerical methods, machine learning surrogate models, and agentic AI capabilities. Our vision is to transform engineering simulation by combining physics-based modeling, data-driven methods, and AI workflows into an integrated engineering platform.

We are seeking a highly motivated intern with interests spanning CFD, artificial intelligence, and product development.

This role offers a unique opportunity to work at the intersection of engineering simulation, AI, and product development. The intern will collaborate closely with software developers, AI engineers, and product managers to evaluate new capabilities, provide technical feedback, and help shape the future direction of AI-enabled engineering software. The position combines rigorous engineering validation with product-focused testing, ensuring that emerging technologies meet the standards required for industrial CFD applications.

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.
