You will be the primary link between complex flight algorithms and custom avionics hardware, developing high-performance C++ applications that ensure deterministic control and absolute system reliability. Working at the intersection of hardware and software, you will collaborate with electrical and GNC (Guidance, Navigation, and Control) engineers to design and implement complex physical-digital interactions with MATLAB/Simulink. WHAT YOUiLL DO Designs, develops, and tests C++ flight software and hardware, sensor, and actuator integrations. Analyzes and decomposes system requirements collaboratively with other engineering disciplines. Writes software requirements specifications, software test descriptions, design descriptions, and test reports Designs, implements, tests, and documents software according to KUAS specifications Mentors mid-level Software Engineers ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Crew Management System for Airlines: Plan duties for pilots & flight attendants worldwide](https://www.wearedevelopers.com/videos/1444-crew-management-system-for-airlines-plan-duties-for-pilots-flight-attendants-worldwide) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Robots are coming into the wild!
