About this position
The Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) in Barcelona is offering a fully funded 4-year PhD position within the national 6G-TENET project, focusing on autonomous and trustworthy 6G networks. The successful candidate will join the SaS and OpenSim research units, which are internationally recognized for their work on 5G and beyond experimental platforms, including the widely used 5G-LENA simulator. Research topics include AI/ML for autonomous network control, trustworthy telco cloud architectures, decentralized cognitive agents, digital twins, large-scale simulations, and future RAN concepts.
The SaS group at CTTC designs architectures and algorithms for next-generation networks, targeting demanding use cases such as automotive, extended reality, IoT, and eHealth. Their work emphasizes the integration of AI/ML for network automation, end-to-end resource management, and the development of experimental research frameworks. The OpenSim unit specializes in open-source network simulation, particularly with ns-3, and develops models and algorithms for virtualized open radio access networks and spectrum management.
The PhD position offers a full-time contract with salary and benefits, PhD enrollment fees covered, paid vacation, flexible working hours, and up to 3 days of telework per week. The research environment is international and inclusive, with access to state-of-the-art labs and simulators. Applicants should have a background in Telecom, Electrical Engineering, Computer Science, Applied Physics, or related fields, and demonstrate motivation, enthusiasm, and the ability to conduct high-quality research. Technical skills in networking, cloud computing, AI/ML, programming (Python, C++), and network simulation are highly valued. The application deadline is March 9, 2026, and the expected start date is before or on June 1, 2026.
To apply, candidates must submit a CV, transcripts, diplomas, and a cover letter via the CTTC online portal. The CTTC is committed to diversity and inclusion, encouraging applications from underrepresented groups. The institution is located in Castelldefels, Barcelona, offering a stimulating work environment close to the Mediterranean coast.
