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.

About The Team & This Role
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. This is a hands‐on role with a discovery‐first approach: the boundaries of the system take shape through the work itself, so you will prototype, validate against real operational constraints, and rebuild what does not hold. You will write code, work directly with the operations specialists who hold the domain knowledge, and lead the development effort that grows around the results. The engineer who builds this becomes a technical reference for mission planning systems and service planning optimisation.
What you'll do
- Determine what the system needs to be. Work with domain experts to draw out real operational constraints, and translate them into concrete, validated technical models.
- Build and lead the development. Design and implement the planning system as a key technical lead, s
