Benefits offered by this job

Flexible schedules

Hybrid work options

Job summary

Eutelsat invites applications for an IRIS2 Satellite Telecommunications Payload Engineer in France. You will manage end-to-end regenerative payloads for LEO satellites, translating mission requirements into payload specifications and budgets, while coordinating with ground networks and suppliers.

You will oversee architecture trade studies, onboard processing functions, and inter-satellite/link interfaces, ensuring performance aligns with constellation objectives and mission success.

Responsibilities

• Oversee the complete lifecycle of regenerative telecommunications payloads for LEO constellation satellites, from initial concept and architecture definition through production, launch, commissioning, and in-orbit operation.
• Translate service, mission, network, and system requirements into payload‑level technical requirements, performance budgets, interface‑control documentation, verification requirements, and unit specifications.
• Define payload functional architectures and allocate functions across RF hardware, digital processors, FPGA and ASIC devices, embedded software, onboard network‑processing functions, inter-satellite links, and ground infrastructure.
• Lead architecture trade studies covering regenerative, transparent, and hybrid payload implementations, including the allocation of processing functions between the satellite and ground network.
• Define and assess onboard processing functions such as digitisation, channelisation, demodulation and decoding, packet or traffic switching, routing, regeneration, re‑encoding, remodulation, beamforming, and dynamic bandwidth allocation.
• Ensure that payload architecture and performance support constellation‑level objectives for coverage, capacity, throughput, latency, service availability, resilience, security, scalability, and graceful degradation.
• Perform and maintain RF, digital, processing, and network performance budgets, including EIRP, G/T, gain, noise figure, linearity, interference, processing capacity, throughput, latency, memory, compute resources, timing, power, and thermal allocations.
• Analyse LEO‑specific communications effects, including Doppler and Doppler‑rate variation, timing and frequency synchronisation, satellite and beam handovers, feeder‑link switching, gateway diversity, moving coverage patterns, and time‑varying interference.
• Contribute to the definition and performance assessment of user links, feeder links, and inter‑satellite links, in close collaboration with ground‑network, terminal, antenna, modem, and system‑engineering teams.
• Assess onboard routing and inter‑satellite connectivity strategies, including traffic steering, path diversity, resilience, congestion management, and coordination with the ground‑based network‑control architecture.
• Analyse and optimise active and phased‑array antenna architectures, digital beamforming, beam steering, beam hopping, coverage allocation, calibration, and dynamic resource‑management functions.
• Lead technical reviews and design evaluations with satellite manufacturers, payload suppliers, and equipment manufacturers, ensuring compliance with RF, digital, software, network, reliability, and system‑
