Sateliot is a Barcelona-based satellite company with one goal: connect everything, everywhere. Founded in 2018, we've built the first satellite constellation that lets standard commercial devices communicate directly from space. Our technology bridges the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet. Learn more: https://sateliot.space/ About the team & this role Sateliot develops its radio access software in-house, for both technologies our constellation serves: NB-IoT and 5G NR, in their non-terrestrial variants. That means satellite links, long delays, Doppler and discontinuous coverage, on real hardware and against real devices — non-terrestrial networks are one of the most active areas in telecoms right now, and here you work on the stack itself rather than on top of someone else's. As Senior RAN Software Engineer you will own radio stack development across both technologies, working closely with our stack architecture lead.



It is a hands-on role for an engineer who wants to build a radio stack, not integrate one. What you'll do Own the design, development and evolution of our in-house radio stacks, with a first focus on NB-IoT: L1, L2 and L3, through to a component we can operate on our target hardware. Put in place the engineering that industrialisation needs: specification-driven development, hardware-independent design, a roadmap tied to the real state of the code, and CI/CD. Work across both radio technologies with the rest of the stack team, bringing hands to whichever one has the hardest problem at the time — the 5G scheduler and beam management among them. Prove the stack on real hardware and real devices — embedded platforms, commercial modules, and the compute and power envelope a satellite payload allows. Turn requirements into features: 3GPP releases, the capabilities our network roadmap commits to, and what the constellation can actually sup
