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.
Sateliot operates a 5G NTN satellite network that delivers standard-based NB-IoT connectivity through mobile network operators, extending their coverage to anywhere on the planet without special hardware. We are scaling from an initial constellation towards service at volume, and that scale changes what planning means for us.
Service and Mission Planning is the capability at the centre of it: determining when and how much service is delivered, by area and by country, against the capacity available — and planning the satellite and ground infrastructure that makes that service physically possible.




We are looking for a senior engineer to establish that capability and to become the person at Sateliot who understands it best. The engineer who builds this becomes a technical reference for mission planning systems and service planning optimisation.
Design and implement the planning system as a key technical lead, setting the direction and scope. Service demand and infrastructure availability must be reconciled continuously. Network operations, as the user of the planning capability and owner of service KPIs and quality of service; and service engineering, as technical authority on network behaviour and 3GPP NTN concepts of operation.
Seven or more years in senior software engineering, with a proven record of designing and deploying resilient production systems.
Deep proficiency in at least one backend language — Python, Go, Java, C++ or similar.
Significant experience with scheduling, planning, constraint-based optimisation or comparably complex systems.
