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. As Senior RAN Test Architect you own how our radio access components get validated — what must be tested, to which criteria, and what counts as evidence — across the NB-IoT and 5G NR non-terrestrial domains, and you are deliberately independent from the engineers implementing them. This is a senior role for someone who writes test specifications, not only test reports.
Own the test specification for our RAN components: what gets tested, against which acceptance criteria, and what constitutes proof that a feature behaves as designed. Build the test pyramid and keep it honest: L1 and RF performance and conformance, protocol stack, load, capacity and stability,



interoperability and field. SDR benches, channel emulation, our own test terminal, and automated regression running in CI. Own the validation of supplier deliveries and the evidence behind what we commit outside the department, working with our field testing teams on the campaigns that close the loop.
Complete ownership of test and validation for cellular radio access, with test specifications you wrote yourself and saw through review with developers, operators or certification partners. The ability to derive a test specification from a 3GPP specification, and to set acceptance criteria that catch real defects rather than produce green dashboards. Ownership of the test system itself: harness and automation design, what belongs in CI and what belongs on the bench, and a regression suite that stays affordable as the stack grows.
Deep lab practice — protocol analysis, SDR benches, channel emulation, load and st
