Overview ? Step into the future of satellite communications with a pioneering organisation at the forefront of space-based 5G technology. With a growing UK footprint and a strong track record in delivering cutting-edge space systems, were enabling the next generation of global connectivity through non-terrestrial networks (NTN). This is a unique opportunity to play a key role in shaping system-level solutions that bridge satellite and terrestrial 5G, contributing to projects that push the limits of what's possible in space and on Earth. The Role As a 5G Systems Engineer, youll be responsible for the end-to-end system definition and performance analysis of advanced satellite payloads and their supporting ground infrastructure. Your focus will include mobile broadband, machine-to-machine applications, and on-board processing solutions aligned with 5G standards. Youll also help shape international standardisation efforts through 3GPP and other key forums. Key Responsibilities Define system-level requirements and architecture for 5G NTN payloads Conduct design trade-offs, performance analysis, and CONOPS development Specify and assess onboard processor requirements and technologies Contribute to risk mitigation and technology maturation strategies Engage with 3GPP and other standards bodies (ORAN, Small Cell Forum) Support proposal development and technical solution presentations Collaborate with internal teams, customers, and partners on system solutions What Youll Bring Degree in Electrical Engineering, Physics, or related field (Masters/PhD preferred) 5 years experience in communications system engineering In-depth knowledge of 5G NR, NB-IoT, and 5G core network architectures Familiarity with payload design, phased arrays, and on-board processing Experience with standards engagement (3GPP, ORAN) highly desirable Strong analytical and communication skills Background working with government or space agencies (e.g. ESA) is a plus Why Apply? Shape future 5G satellite architectures with real-world impact Collaborate with top-tier engineers and industry leaders Be part of a dynamic, growing team contributing to meaningful space missions Enjoy opportunities for innovation, learning, and global collaboration If you're ready to help build the next generation of satellite-powered 5G systems, apply today and be part of the journey. ?
