The Mission of the Software Engineer, Unmanned Aircraft

As Software Engineer on the HAPS program, you will develop and maintain the custom software that keeps ICEYE's stratospheric electric aircraft flying — spanning the full stack from embedded avionics and command & control systems to simulation environments and ground-based tooling. You will integrate COTS and custom avionics components into a working UAV platform, build and improve hardware-in-the-loop and software-in-the-loop simulation systems, and participate directly in flight test campaigns — turning real-world data into software improvements that push the aircraft's capabilities forward.
