About the role

Key responsibilities & impact

Design, develop, and implement simulation software for testing and verifying TeraWave's flight software.
Collaboration with test team leads to develop a simulation environment that can be deployed on multiple platforms to support software-only test, HWIL test, real-time environment tests, and spacecraft AI&T.
Collaborate with hardware, systems, and autonomy engineers to understand software requirements, interfaces, and behavioral boundaries across subsystems.
Develop and integrate simulation environments and models to test FSW across a range of nominal and off-nominal operational scenarios.
Participate in software integration, verification, and validation testing including software-in-the-loop (SIL) and hardware-in-the-loop (HIL) environments.
Background support of on-orbit operations and troubleshooting of deployed spacecraft.
Mentor junior engineers and contribute to team technical development.
