ROLE DESCRIPTION SUMMARY

We are seeking a Senior UHF Payload Systems Engineer to lead the technical definition, de\-risking, and validation of UHF services hosted on MEO satellites within the IRIS² programme.

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.

The position requires a strong system engineering mindset, combining RF and satcom expertise with experience in satellite payload design and testing, ideally in UHF satcom systems.

PRIMARY RESPONSIBILITIES / KEY RESULT AREAS

• 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

Required Qualifications \& Experience

• Master’s degree or PhD in Telecommunications, RF Engineering, Aerospace Engineering, or related field


• Minimum 5\+ years of experience in satellite communications, with strong focus on UHF payloads or satcom services


• Proven experience with:

+ UHF satcom system development and/or deployment (highly desirable)
+ RF system design, link budget analysis, and antenna systems
+ Satellite payload integration and system engineering
+ Simulation tools (e.g. MATLAB, Python, RF tools)

Key Technical Skills

• Deep understanding of:

+ Satellite link budgets and propagation effects
+ Mobility, Doppler, and NGSO system behaviours

• Knowledge of UHF satcom systems and waveforms, e.g. STANAG 4681, MIL\-STD\-188

Key Personal Attributes

• Strong creative engineering mindset


• Excellent stakeholder management across multi\-partner environments


• Structured, analytical, and solution\-oriented approach

OTHER KEY REQUIREMENTS / COMMENTS

• The candidate must be eligible for a “SECRET” security clearance, in accordance with the national regulations as well as EU/ESA/NATO equivalents


• Willing to work 60% onsite from office


• Travel as required for project realization purposes
