This role calls for a professional who can understand, define, and innovate macro-level architecture concepts, and translate them into highly detailed, practical specifications. You will be highly hands-on, possessing the ability to define, model, and deploy complex setups used to validate and develop the NTN architecture. In this multidisciplinary role, you will oversee deployment tasks across critical engineering domains. This includes: * Lead the definition and development of Meridian Non-Terrestrial Radio Access Network (RAN) architecture. * Own the requirements engineering, system specifications, traceability, concept of operations, and roadmap definition for Meridian ground segment RAN throughout its architecture and space segment interfaces. * Drive RF system design, analysis and simulation work including link budgets, and antenna systems architecture for the Meridian ground segment. * Execute beam design and coverage modelling including live testbed analysis of all NTN channel aspects. * Lead the lab/testbed build, automating test execution, and conducting KPI measurements across complete end-to-end architecture. * Collaborate with network core, OSS, and space segment architects to ensure end-to-end coherence of the Meridian RAN solution. ## Related Videos - [Unleash the power of 5G in your code: transform your apps](https://www.wearedevelopers.com/videos/1567-unleash-the-power-of-5g-in-your-code-transform-your-apps) - [Location Verification without GPS?](https://www.wearedevelopers.com/videos/1184-location-verification-without-gps) - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The CAMARA Project: How Telcos Collaborating Improves Developer Experience](https://www.wearedevelopers.com/magazine/671-the-camara-project-how-telcos-collaborating-improves-developer-experience) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk)
