Job Overview

:

As a Senior Software Engineer focused on Simulations, you will lead the development of high-fidelity physics-based simulations for end-to-end missile flight and guidance validation. These simulations serve as a digital proving ground for our flight software, autonomy stack, and control systems—enabling us to iterate rapidly and validate in silico what would otherwise require expensive, slow, or impossible real-world testing.

You’ll own simulation architecture, real-time physics integration, and testbed development. If you’re comfortable writing performant simulation code in Rust and Python, and you’re looking to do impactful work on a system that must work the first time, this is your chance.
