Software Engineer, Simulation

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. SOFTWARE ENGINEER, SIMULATION As a software engineer on the NDE & Materials Software team, you will develop, improve, and advance our in-house multi-physics simulation engine—currently supporting high-pressure die casting and investment casting processes—to the next level. This role will expand the engine's capabilities to additional manufacturing domains, including additive manufacturing, welding, structural stress and strain analysis, grain prediction, and more. You will help apply these simulations to increase part yield, reduce inspection burden, and optimize parts across Raptor, Starship, Starlink, and other programs at SpaceX. Strong software engineering skills and experience applying Machine Learning (ML) and AI to simulation solutions are key to success. The team consists of world-class experts in solidification physics, casting, metallurgy, and simulation. Experience with casting or solidification is not required—just a desire to learn, collaborate, and enable the best future for manufacturing at SpaceX. RESPONSIBILITIES: Own software architecture and quality of simulation software used across SpaceX. Develop and optimize next-generation software that integrates CFD tools, meshing software, and CAD platforms for multi-physics simulations; contribute to transitioning results viewing to web-based 3D tooling. Build advanced interfaces for viewing and interpreting simulation results. Troubleshoot and debug issues related to software integration, meshing quality, and simulation accuracy. Leverage machine learning and AI solutions—such as surrogate modeling and physics-informed neural networks—to accelerate simulations, enhance efficiency, drive novel improvements, increase part yield, r
