WHO ARE WE? Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide general 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 We’re looking for a Senior Protocol Stack & Network Automation Engineer to define, evolve, and operate the end-to-end protocol stack connecting space links/RF ground systems, ground stations, and terrestrial + cloud networks. This role is for someone with exceptionally strong networking fundamentals (from first principles), hands-on space/RF protocol stack experience, and a maker mindset—someone who loves building lab setups, validating assumptions,



and turning complex networking/protocol problems into repeatable, automated solutions YOUR MAIN FUNCTIONS Own the Space ↔ Ground ↔ IP protocol stack (core accountability) Define and document the protocol stack across space links, ground systems, ground station networks, and IP/cloud environments. Work hands-on with space protocol stacks and their operational implications, including CCSDS-based stacks (e.g., AOS, PUS) and DVB-S2 with ground-segment adaptation (e.g., GSE or equivalent patterns used in real systems). Design and implement approaches to map / bridge / encapsulate / translate between stacks and networking domains (space ↔ ground station ↔ IP), including constraints like MTU/fragmentation, latency/jitter, loss, ordering, and retransmission behavior. Partner with Ground/Space/Software teams to ensure protocol choices are implementable, testable, and operable. Build and operate reliable networks (vendor
