Sr. Simulation Software Engineer (Application Software)
Posted Apr 30, 2026
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. SR. SIMULATION SOFTWARE ENGINEER (APPLICATION SOFTWARE)
As a Software Engineer on the Simulations team, you will design, develop, and test our in-house simulation software supporting all SpaceX flight systems. You will program the core simulation infrastructure and collaborate on the building of models of fluids, electronics, and multi-body physics systems. This is a high impact role where you will work across the engineering groups to build high fidelity simulations used to develop cutting-edge software and hardware. Our simulation software is critical to current and future mission successes including Falcon, Falcon Heavy, Dragon, Starlink, and Starship. SpaceX is looking for smart, motivated software engineers who enjoy taking on complex challenges, work well in dynamic environments and care about software best practices. Help us build world class software that is critical to SpaceX mission to Mars. RESPONSIBILITIES:
- Develop and maintain the high-fidelity real-time simulation software used for all vehicles
- Develop prototypes to prove out key design concepts and quantify technical constraints
- Maintain the highest standards of excellence, never settle for the status quo
- Improve reliability and performance of simulation software
