Description

Hispasat, as part of the SpaceRISE consortium, is responsible for the technical implementation and for ensuring the success of the IRIS² project, leveraging its extensive experience in satellite communications. This collaboration is essential to provide secure, reliable and high-performance communication solutions to the European Union and its Member States.

To be part of this project, we are looking for a 5G Payload Engineer. The responsibilities of the position are as follows:

Responsibilities
- Architect and implement a 5G NTN network from satellite, including the flight and ground segment components, in a secured environment.
- Design and develop digital signal-processing algorithms for 5G wireless and satellite-communication systems.
- Define, model and simulate algorithmic prototypes in MATLAB or equivalent environments.
- Collaborate with payload, systems and software teams, including High-Level Synthesis workflows where applicable.
- Collaborate with cross-functional teams to define upcoming solutions for SAT network architecture.




- Preparation of reviews for payload design, manufacturing, acceptance and testing, working closely with the platform and systems teams.
- Develop end-to-end simulations, reference models and payload-processing chains for 5G NR and future NTN capabilities.
- Integrate and validate end to end network connectivity across Open RAN, gNodeB, 5G Core, IMS, transport, and LEO satellite test systems.
- Partner with RF, modem, payload, Core, RAN, software, and systems teams to define the overall system architecture, implementation, test and operations from ambiguous system behavior to clear resolver ownership.
- Validate and optimise performance across representative channel models, test vectors and operational scenarios.
- Validate VoNR and IMS call flows, including registration, SIP signaling, media path, QoS, emergency call behavior where applicable, and failure recovery
- Support trade-off analyses involving latency, thro
