RAN Test Engineer — NTN eNodeB and gNodeB

• Real impact in one of Europe's most ambitious space projects.

• Growth: we cover 50% of courses or master's degrees (up to 5% of your salary), in addition to Spanish and Catalan classes.

• Health and balance: we cover 50% of private medical insurance and a discount on Wellhub. You have flexible hours and hybrid work, because we focus on results, not hours.

• Flexible compensation through Cobee (meals, transport, childcare).

• A global team: more than 20 nationalities building something new, with people who are a pleasure to work with. Good atmosphere and real teamwork.

• A real welcome: a buddy assigned from day one.

• Life beyond work: we organize leisure and sports activities inside and outside of working hours, because good teams connect beyond the screen.

• Catering: if you don't have time to cook, we work with a catering company so you can have a fresh meal without thinking about it.

• Parking: parking at the office with 50% of the cost covered by Sateliot, and free bike parking if you prefer to come pedaling.

Sateliot is a satellite company based in Barcelona with one goal: to connect everything, everywhere. Founded in 2018, we have built the first satellite constellation that allows standard commercial devices to communicate directly from space. Our technology reaches where terrestrial networks never will and brings affordable and secure connectivity to industries, governments, and communities across the planet.

At Sateliot, we bring standard cellular connectivity from space and develop key pieces of our radio access technology in-house. This means that every functionality we write must prove that it works before reaching orbit. This role is the practical side of that work: managing the laboratory testbeds where we test our NB-IoT and 5G NR non-terrestrial base stations, and building the automation that allows us to repeat those tests with every change. You will work alongside the engineers developing the stack and the architect who defines what needs to be validated. If you want to end up writing radio access software and not just testing it, this role is a gateway: those who know the test system best are those who understand the stack first.

• Manage testbeds: prepare and execute test campaigns on our NTN eNodeB and gNodeB, using SDR equipment, channel emulation, and our own test terminal.

• Build test automation and take responsibility for it: convert manual campaigns into regression suites that run with every change, and maintain them fast enough so that the team actually uses them.

• Execute the test specifications defined by the RAN Test Architect and point out what they miss when you have the equipment in front of you.

• Analyze protocol traces and logs to determine where the failure is (stack, device, or link) and report it in a way that a developer can act without reproducing it from scratch.

• Keep the laboratory operational: configuration, equipment, and the record of what has been tested with which build.

• Support field test campaigns and in-orbit validation when a functionality reaches that phase.

• Grow into the stack: you will work alongside those who develop it, with a senior engineer who will review what you build and the necessary mentoring to move from testing radio access software to writing it.

• Reside in Barcelona: the laboratories and the team are here, and the position requires hands-on work with the equipment.

• Availability to travel occasionally for field test campaigns.
