Space Optics System Engineer

In this role you develop engineering systems for ESA optical stations, focusing on optical quantum communications. You’ll define technical specifications, lead design reviews, and support technology development within a space optics context. You collaborate with cross‑functional teams to address challenging quantum communication problems and enable secure space-based links. This is a mission-driven position that combines advanced optics with quantum security in a globally distributed environment.
