Fluid Simulation Engineer at DeepSim, Inc.

We are looking for a Fluid Simulation Engineer with deep expertise in numerical simulation of fluid flow. You’ll play a key role in advancing DeepSim’s core simulation engine by designing solvers, modeling complex flow regimes, and enabling high-performance inference for large-scale engineering use cases. Develop, implement, and optimize CFD/FEM-based fluid solvers for convection and heat transfer PDEs with multiphysics interactions. Investigate and enhance solver stability, accuracy, and performance across a variety of regimes and geometries. Build core simulation components and modeling pipelines that support AI-driven simulation frameworks. Collaborate with AI and systems engineers to create hybrid numerical/ML simulation architectures. Evaluate new numerical techniques, discretization strategies, and high-performance computing optimizations. Strong background in fluid simulations using CFD or FEM methods. Deep understanding of numerical solver mechanics and experience building CFD/FEM tools from scratch or modifying existing open-source frameworks. Proficiency in Python and C/C++ , with experience writing high-performance and maintainable scientific code. Familiarity with HPC e
