Level of qualifications required : Graduate degree or equivalent
Fonction : Temporary scientific engineer
The Inria Center at the University of Rennes is one of Inria’s eight research centers and is home to more than thirty research teams. The center is a major and internationally recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem, bringing together highly innovative SMEs, large industrial groups, competitiveness clusters, research and higher education institutions, laboratories of excellence, and a technological research institute.
The Bpifrance i-Démo program, funded under the France 2030 investment plan, supports ambitious collaborative research, development, and innovation (R&D&I) projects with strong technological and economic impact. It aims to accelerate the development of breakthrough technologies and their transfer to the market by fostering collaboration between industrial companies and research organizations.
The ROBIN project is funded under this program and brings together a consortium of two academic partners (INSA Rennes and the University of Rennes) and three industrial partners (TDF, Ateme, and ENENSYS). Together, they are developing innovative solutions for 5G broadcast technologies, with a particular focus on the delivery of broadcast services to 5G terminals.
The evolution of digital broadcasting and mobile networks has led to the emergence of 5G Broadcast technology, enabling the delivery of high-quality multimedia services, including TV and video content, directly to 5G-enabled terminals. This technology relies on a combination of advanced terminal architectures, communication protocols, and standardization frameworks defined by organizations such as 3GPP.
However, several scientific challenges remain to be addressed, including the optimization of physical and protocol layers, the design of efficient and robust 5G Broadcast base station architectures, and the development of adaptive transmission strategies capable of addressing heterogeneous and dynamic propagation conditions across indoor and outdoor environments.
Artificial Intelligence (AI) and Machine Learning (ML) techniques offer promising approaches for improving system performance through data-driven optimization, intelligent resource management, and adaptive configuration. Nevertheless, challenges related to robustness, generalization, reliability, and computational complexity must be considered to ensure the deployment of AI-based solutions in real-world 5G Broadcast systems.
The Research Engineer will be responsible for the design, deployment, and validation of a 5G Broadcast experimental testbed based on USRP platforms, OpenAirInterface (OAI), and associated radio communication equipment. The mission will involve setting up an end-to-end experimental infrastructure, including hardware integration, 5G protocol stack configuration, signal generation and analysis, and performance evaluation.
The engineer will contribute to the deployment of indoor and outdoor test environments for evaluating 5G Broadcast services under realistic propagation conditions. Activities will include the configuration and operation of radio equipment, antenna systems, measurement tools, and network components, as well as the management of frequency resources, spectrum access, and required experimental licenses.
The position will involve:
Net monthly salary ranging from approximately €2,500 to €3,100, depending on experience.

Defence Security :
This position is likely to be situated in a restricted area (ZRR), as defined in Decree No. 2011-1425 relating to the protection of national scientific and technical potential (PPST).Authorisation to enter an area is granted by the director of the unit, following a favourable Ministerial decision, as defined in the decree of 3 July 2012 relating to the PPST. An unfavourable Ministerial decision in respect of a position situated in a ZRR would result in the cancellation of the appointment.
Recruitment Policy :
As part of its diversity policy, all Inria positions are accessible to people with disabilities.
More than a checklist of technical skills, what will make this assignment a success is a particular mindset and a certain way of engaging with research and engineering work.
The ideal candidate is someone who genuinely enjoys operating at the boundary between systems and ideas — someone who finds satisfaction not only in making things work, but in understanding why they work and what they reveal about the underlying problem. This role sits at the crossroads of distributed systems, AI, and networking: an intellectual appetite for all three, even without deep expertise in each, will go a long way.
We are looking for someone with:
A taste for experimentation and hands-on work. You enjoy building things, running experiments, and letting measurements guide your thinking. You are not deterred by a system that does not behave as expected — you are curious about why.
Comfort with open-ended problems. The scope of this project will evolve. The right candidate embraces this flexibility rather than seeking rigid task definitions, and is able to self-direct their work within a broader research agenda.
A collaborative and communicative nature. The project involves a multi-partner national programme (PEPR NF-MUST). You will interact with researchers from different institutions and backgrounds, and you are able to share your progress, your doubts and your findings clearly and constructively.
Cross-disciplinary curiosity. Whether your background is closer to systems, algorithms, or networking, what matters is a genuine interest in the neighbouring fields and a willingness to build bridges between them.
A research-oriented mindset. You are comfortable reading technical literature, situating your work in a broader scientific context, and contributing to written outputs that go beyond code documentation.
A thesis or significant project in the areas of network function virtualisation, edge computing, machine learning systems, or distributed optimisation would be a genuine asset. What matters most is the drive to produce rigorous, reproducible, and impactful work within a stimulating and supportive research environment.
