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. We are seeking a skilled engineer to develop and maintain software that integrates open-source CFD tools, meshing software, and CAD platforms, focusing on computational fluid dynamics (CFD), meshing, and simulation workflows. This role requires strong software development experience, including C++ and Python, along with expertise in numerical solvers and CAD tools. Our team is building out our in house multi physics simulation engine to support multiple manufacturing processes at SpaceX. Our in house simulation software enables our partner teams to accelerate their production rates and improve the quality of resultant parts to push the boundaries of manufacturing for Raptor, Starship, Starlink, and other programs at SpaceX. Our team consists of world class experts in solidification physics, casting, metallurgy, and simulation. We are looking for a strong software engineer to take the simulation and associated tools to the next level of maturity. Experience with casting or solidification is not required – just a desire to learn, collaborate, and enable the best future for manufacturing at SpaceX.
