Inclusion statement

## Description

Your missions :
As a Software Engineer, you will design, develop and continuously improve software to deliver high-quality applications, services and technologies that provide value to end users.

You will contribute to improving our solutions based on usage and user feedback, while working on advanced technologies at the intersection of software development, simulation and High Performance Computing.

Rapid execution of complex simulations is a key component of the SIMULIA MODSIM approach and an essential requirement for competitive simulation solutions.

To accelerate the deployment of multi-GPU simulation solutions, we are looking for a Software Engineer to join a team focused on High Performance Computing (HPC), with a particular emphasis on GPU development for fluid simulation technologies.

In this role, you will contribute to the development and optimization of software running on GPU-based computing architectures. You will work with C++ and CUDA and collaborate with specialists from different scientific and technical backgrounds to address complex simulation challenges.

You will have the opportunity to work on CFD algorithms and approaches, including one or more of the following:

 * Lattice Boltzmann methods;
 * Continuum approaches to Navier-Stokes, including finite volume or finite element methods;
 * Lagrangian formulations, such as SPH or DEM;
 * Ray tracing methods;
 * Linear equation solvers.
