You'll be part of a close-knit, collaborative team that thrives in a fast-paced, innovative environment, where your work directly advances the design, development, and deployment of satellite constellations that governments and enterprises around the world will depend on for secure, resilient, and sovereign connectivity.\nYour Mission on the Team:\nAs our RF & NTN Propagation Engineer, you will own the physical layer RF architecture, signal propagation analysis, and link performance for the Meridian 5G Non-Terrestrial Network (NTN) solution. This role calls for a highly analytical engineering professional who can bridge theoretical RF concepts with practical implementation and testing in a cutting-edge LEO environment.\nIn this critical domain, you will oversee the deployment of RF analysis tasks and ground segment hardware validation. This includes:\nDriving RF system design, analysis and simulation work including link budgets, and antenna systems architecture for the Meridian ground segment. \nExecuting beam design and coverage modelling include live testbed analysis of all NTN channel aspects. \nDeveloping, analyzing, and validating complex NTN channel models involving severe delay, Doppler shifts, and fading. \nCollaborating with RAN, RF, and systems architects to ensure end-to-end coherence of the Meridian solution. \nContributing to the design and operation of lab environments used to validate architecture and configuration choices. \nLeading the lab/testbed build, automating test execution, and conducting KPI measurements across complete end-to-end architecture.\nBasic Qualifications:\nBachelor's degree in electrical engineering, computer science, telecommunications, or a related field. \nExperience with RF system design, link budgets, and NTN channel models involving delay, Doppler, and fading. \nExperience executing beam design and coverage modelling. \nExperience in the design and/or operations of satellite networks, satellite ground segments, and ground segment components/systems. \nExperience in system engineering and architecture specifications across a complex system of systems architectures implemented by multiple multidisciplinary teams. \nStrong interpersonal, verbal, and written communication skills, with the ability to collaborate across RF, RAN, core, security, and business stakeholders.\nPreferred Qualifications:\nMaster's degree in electrical engineering, computer science, telecommunications, or a related field. \nFamiliarity with 5G NTN or SATCOM ground segment architecture. \nFamiliarity with emulator-based testbeds (e.g., Keysight/Spirent) and CI/CD for test automation. \nProficiency in scripting and automation (Python, Bash, or similar). \nPrevious participation in standardization fora (3GPP, O-RAN, ETSI NFV) or open-source telco projects. \nExperience working in ESA, defense, or similarly regulated environments.\nMeridian Space UK Limited is committed to creating a diverse environment and is proud to be an equal opportunity employer.
