Sateliot is a satellite company based in Barcelona with a single goal: to connect everything, anywhere. Since 2018, we have built the first satellite constellation that allows standard commercial devices to communicate directly from space. Our technology covers the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet.

We are looking for a Roaming and Billing Integration Specialist to lead and coordinate the technical integration of mobile network operators (MNOs) into our satellite IoT connectivity service.

The role sits at the intersection of mobile network integration, roaming, service operations, and billing. You will be the technical point of contact throughout the onboarding process for each MNO: from initial technical alignment and connectivity configuration to roaming validation, service launch, billing testing, and subsequent operational support.

The ideal person combines good knowledge of mobile telecommunications networks and roaming with technical project management and stakeholder coordination skills. This is not a purely technical Core Network engineering position. We are looking for someone capable of driving integrations from start to finish, coordinating multiple technical teams and partners, detecting dependencies, and ensuring each integration progresses until it is ready for commercial launch.

• Lead the complete technical integration of MNOs, from initial assessment until they are ready to operate commercially.

• Act as the primary technical interlocutor with MNOs and coordinate internal teams, IPX providers, and other external partners.

• Drive the resolution of technical incidents to unblock any obstacles throughout the integration.

• Coordinate IREG and TADIG exchanges, roaming tests, and end-to-end service validation.

• Lead the technical coordination and end-to-end billing validation with MNOs. This includes coordinating billing test scenarios (usage generation, TAP/DCH exchange, and reconciliation), working with MNOs, clearing houses, and internal teams to detect and resolve discrepancies, and ensuring that billing is validated before commercial activation and production handover.

• Ensure that all network, roaming, and billing requirements are closed before the commercial launch with each MNO, and coordinate the handover of new integrations to standard service operations.

• Monitor integration and service KPIs and drive improvements when necessary.

• Continuously standardize and improve the MNO onboarding and integration process to make it more efficient and scalable.

We are looking for someone who combines technical telecommunications knowledge with a sense of responsibility and the ability to execute.

The selected person must feel comfortable talking about network configurations with engineers, billing flows with roaming teams, and integration milestones with project stakeholders.

They must be able to take on an integration with an MNO, understand what needs to be done at a technical level, identify the teams and partners involved, set up a clear plan, track dependencies, and drive the integration until the service, including billing, is fully validated and ready to operate commercially.
