(Senior) Engineer, UHF Payload Systems, IRIS2

Within the IRIS² MEO Space Segment team, the incumbent will contribute to the definition of the end-to-end MEO UHF service architecture by developing space segment technical specifications as well as satcom system analyses for the end-to-end service. The incumbent will collaborate to define the derisking activities with the selected supplier and monitor the derisking roadmap execution., * Contribute to the definition of the end-to-end MEO UHF service architecture

• Translate UHF mission and service requirements into system and payload-level specifications accounting for satellite constellation constraints

• Contribute to design trade-offs (coverage, power, SWaP, performance) and payload architecture

• Perform system-level performance analyses for UHF services

• Define interfaces with spacecraft platform, main payload, user ground segment and mission control segment

• Interface with payload providers, terminal vendors, and subsystem suppliers for statement of work negotiation, technical specifications and test plans

• Define and support integration, verification, and validation (IVV) activities for UHF services (unit-level testing, payload AIT, IOT)

• Contribute to development of simulation tools and digital twins for payload performance and IVV
