## Description

As a Simulation Software Engineer on the Starlink GNC team, you will help develop and maintain our in-house vehicle dynamics simulator, as well as related infrastructure for dispersed Monte Carlo simulations, hardware-in-the-loop (HITL) simulations, and GNC-specific data visualization. You will program the core simulation infrastructure and collaborate on the building of models to accurately represent multi-body physics, environmental perturbations, and vehicle power/propulsion/control hardware. 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. 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., + Maintain in-house simulator as it pertains to Starlink and make continual improvements to help that system scale in performance and capability along with our constellation

 + Maintain and improve the SpaceX GNC Monte Carlo simulation infrastructure as it pertains to Starlink

 + Work with simulation software users to develop new features and models, and to improve user experience

 + Improve reliability and performance of simulation software via continuous integration, profiling, etc
