5G RAN Integration Engineer

WHO ARE WE?

Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that will make up the massive Internet of Things (IoT) universe under the 5G protocol.

In order to do so, Sateliot is launching a constellation of last generation nanosatellites, located at low altitude that act as mobile towers. Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive.

YOUR MISSION

In your role as an 5G RAN Integration Engineer, you will be immersed in a collaborative and adaptive environment, where your efforts will have a substantial impact across all elements of the Sateliot solution - from terminals to constellation and service management software, encompassing critical components such as satellite payload, 5G NR Stack and 5G core network softwares, and ground segment components. Your contributions will be crucial throughout various phases of the Sateliot solution evolution, from conceptualization and lab testing to in-orbit testing and the operational phase of the service.
