High quality ground support systems are crucial for quick and efficient test and launch cadence. As a Ground Avionics Engineer at an early-stage start-up, you will develop state of the art software tools and pair them with robust hardware to facilitate ground test and launch activities. You will work with flight avionics to incorporate flight components into ground testing in order to build component test heritage. You will architect ground test and launch systems with commonality so that test stand lessons learned can be applied directly to launch activities. You will continuously iterate to improve speed, safety, and efficiency. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
