Masters degree preferred. * Experience developing, maintaining, and validating software models of complex systems. * Experience developing software collaboratively as part of a team and the associated software development techniques and best practices. * A strong technical understanding of JULIA or Python, and experience with other coding languages (MATLAB, C++, SQL) * A collaborative nature and strong ability to communicate across multiple stakeholder levels and work across organisational boundaries. * A technical understanding of RF communications engineering. * Experience working with LEO/MEO/GEO satellite communication systems and their CONOPS. * Knowledge of current 3GPP standards. ## Description We are looking for an enthusiastic and skilled IRIS2 Systems Modelling Engineer to join our team and play a critical role in the modelling and simulation of our Next Generation communication systems. In this position, you'll sit within the End-to-End Systems Engineering organization and work closely with the systems architecture team, software engineering, operations, and the commercial side of the business. You'll contribute directly to our ongoing projects and initiatives. This is a unique opportunity to make a significant impact within an organization that values growth, teamwork, and professional development. Who You Are: You're a whiz in all things systems engineering and systems modelling, who can identify connections and dependencies in highly complex systems. You combine your strong technical background with programming to develop, validate, and maintain system models/simulators of varying scope and fidelity to meet the needs of the engineering organisation and the wider business. You're a capable self-starter and love to learn. You're sparked by a fast pace, with new challenges, and the opportunity to learn/invent new techniques. You're a self-motived creative thinker who works collaboratively and is ready to produce results. You can produce rigorous, model-based analyses and can explain the results to both technical and non-technical audiences. You possess superb communications skills with the ability to work across organisational boundaries. What You'll Do: * Work collaboratively with the rest of the System Modelling and Tooling team to continue to develop our in-house system performance simulators. * Use the system performance simulators to perform modelling analyses to support the specification and design of Eutelsat Group's Next-Gen payloads, platforms, and ground network. * Perform modelling analyses of end-to-end system level performance and present the results to a wider (sometimes non-technical) audience. * Draw conclusions from modelling analysis results on how subsystem and system level performance could be improved and provide technical feedback to the Systems Architecture team.
