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

Your mission is to lead the end-to-end delivery of full-stack projects, from API architecture and database design to the frontend interface. You will champion best practices in code quality, testing, and cloud integration.

While you will perform rigorous code reviews and mentor other engineers when needed, your primary focus will be hands-on development, solving complex technical challenges and ensuring the reliability of our web platform stack.
