## Description

We are seeking a Satellite Communications Systems MBSE Engineer to play a key role in the design, integration, and delivery of a Medium Earth Orbit (MEO) satellite constellation and its associated ground system. The program delivers broadband services notably using cutting-edge technologies such as advanced on-board digital processing or 3GPP 5G Non-Terrestrial Networks (NTN) protocols, requiring close coordination across space, ground, and terrestrial network domains., * Develop models using model-based systems engineering (MBSE) methods to contribute to the system-level architecture, design and concept of operations for a MEO satellite communications system, focussing on the space segment in relations with the ground and user segments

 * Develop models following MBSE methods to contribute to the design, specification and integration of the main payload and ancillary hosted payloads
 * Contribute to the definition and review of system requirements across satellites, gateways, network functions, and terminals
 * Collaborate with RF, payload, spacecraft, ground infrastructure, and software teams to ensure cohesive system performance
 * Support ground system design, including gateways, mission control, and interfaces to terrestrial networks
 * Support the definition of system verification and validation (V&V) strategies, including simulations, test campaigns
 * Interface with customers, partners, and external stakeholders on system design and operational topics
 * In the execution of these tasks, you will be supported by experts from the Project team.
