The University of Luxembourg, a modern and international research university, is offering a PhD position in Multi-Connectivity for Multi-Orbit Satellite Systems within its Interdisciplinary Centre for Security, Reliability and Trust (SnT). The successful candidate will join the SIGCOM research group, led by Prof. Symeon Chatzinotas, which specializes in telecommunication and networking systems, including non-terrestrial networks (NTNs) and quantum communication infrastructure. The research will focus on developing advanced reliability and connectivity techniques for multi-orbit satellite systems, such as GEO-MEO-LEO architectures, in close collaboration with the industrial partner SES. Key responsibilities include designing and evaluating multi-connectivity frameworks, optimizing and experimentally validating MC-based reliability solutions, and disseminating findings through scientific journals and conferences. Applicants should possess an M.Sc or M.Eng degree in Electrical and Electronics Engineering, Telecommunications Engineering, or Computer Science/Engineering, with strong backgrounds in digital signal processing and mathematics. Experience or interest in wireless, mobile, satellite communications, NTNs, 5G/6G technologies, communication system modelling, performance analysis, simulation, optimization, and machine learning is expected. Hands-on experience with software-defined radios (SDRs) and/or OpenAirInterface5G software stack, as well as programming skills in MATLAB, Python, or C/C++, are desirable. Fluency in English is required, and knowledge of French, German, or Luxembourgish is advantageous. The position offers a fixed-term contract of 36 months (extendable up to 48 months), a yearly gross salary of EUR 41,976, and access to high-quality equipment and a dynamic, multicultural environment. The University of Luxembourg is committed to gender parity, inclusion, and diversity. Applications should include a full CV, transcripts, cover letter, and should be submitted online via the university's HR system. Early applications are encouraged as they will be processed upon reception.

The University of Luxembourg, a modern and international research university, is offering a postdoctoral position in 5G/6G Non-Terrestrial Networks (NTN) and Satellite Communication Testing at its Interdisciplinary Centre for Security, Reliability and Trust (SnT). The centre is renowned for its research in secure, reliable, and trustworthy ICT systems and services, and collaborates closely with industry and European institutions. The successful candidate will engage in cutting-edge research on the latest and upcoming 3GPP radio access and core network standards, focusing on the implementation of features in MATLAB and OpenAirInterface for computer simulations, and theoretical research aimed at patenting and future standard releases. Key research areas include NTNs, Multicast and Broadcast Services, UAVs, UAS, Urban Air Mobility, and the development of experimental emulators, prototypes, and distributed testbeds. The role involves setting up real-world testing environments using emulators, software defined radios (SDRs), drones, and satellites to validate research outcomes. Responsibilities also include disseminating results through high-impact publications and conferences, contributing to research proposals for industrial, national, and European funding, and supporting the supervision of PhD students. Applicants must have a PhD in Telecommunication Engineering, Electrical Engineering, or Computer Science/Engineering with a focus on wireless communications, and demonstrate proficiency in relevant programming languages and open-source software frameworks. Experience with Linux, SDRs, Docker, virtual machines, and network simulation tools is highly valued. The position offers a fixed-term contract of 24 months with a competitive annual gross salary of EUR 83,099, access to high-quality equipment, and a vibrant, multicultural working environment. The University of Luxembourg promotes an inclusive culture and encourages applications from candidates of all backgrounds. Applications should be submitted online and include a CV, cover letter, publication list, degree details, thesis summaries, and referee contacts. Early applications are encouraged as review is ongoing.
