Apply today and help us build a more inclusive, sustainable future in the world of satellite technology Role Overview Eutelsat is seeking an experienced End-to-End System Performance & Sizing Engineer to lead the definition, optimisation and assessment of system sizing and performance for next-generation satellite communication networks. This role spans all system domains, including user terminals, space segment, ground segment, network infrastructure, service platforms and operational systems. You will ensure that independently designed and delivered system elements collectively achieve the targeted end-to-end service objectives in terms of capacity, latency, availability and scalability. Working at the intersection of systems engineering, performance modelling and solution architecture, you will define key performance budgets and targets, drive cross-segment design trade-offs, and coordinate the development and application of performance models to demonstrate compliance with mission and service requirements.

Key Responsibilities
* Lead a multi-disciplinary work stream composed of system, segment and modelling engineers.
* Contribute to the definition, maintenance and evolution of system sizing assumptions and performance budgets.
* Contribute to the maintenance of the end-to-end system engineering database and ensure consistency of the overall system definition.
* Coordinate modelling and simulation activities and define requirements for performance-tool enhancements.
* Lead end-to-end performance assessments covering capacity, latency, availability and service scalability.
* Ensure performance tradeoffs, analyses, assumptions and conclusions are appropriately documented and traceable.
* Drive complex cross-domain trade studies involving user, space, ground and network segments
* Identify, quantify and communicate performance bottlenecks, technical risks and design constraints.
* Define performance requirements and sizing allocations for system segments and suppliers.
* Translate mission and service needs into measurable, traceable and verifiable system performance requirements.
* Interface with business, program and engineering stakeholders to present performance assessments and justify design choices.
* Interface with industrial partners and suppliers to influence design decisions and assess compliance with system requirements.
* Contribute to requirements verification, validation and statements of compliance.
* Ensure alignment and traceability between mission, system and segment-level requirements. Required Experience
* 5-10 years of experience in systems engineering, system architecture, system performance engineering, modelling and simulation, or end-to-end architecture of complex telecommunications systems.
* Master’s degree or PhD in Telecommunications, Electrical Engineering, Aerospace Engineering, Computer Science, Applied Mathematics, or a related discipline.
* Experience in satellite communications, non-terrestrial networks (N
