Postdoctoral researcher in reproducible experimentation on network performance in datacenters – Fixed-term contract 18 months

A leading general engineering school of IMT-Institut Mines-Télécom, France's foremost group of engineering schools, IMT Atlantique aims to support transitions, train responsible engineers, and leverage scientific and technical excellence for teaching, research, and innovation.

As part of the ANR NET4AI project, which aims to make the infrastructures used to train and operate generative AI models more efficient (observability, collective communications, energy efficiency), we are recruiting a postdoctoral researcher (female or male) within our Automation, Production, and Computer Science Department (DAPI), STACK team.

Under the scientific supervision of Remous-Aris KOUTSIAMANIS and in collaboration with the researchers, engineers, and partners of the Net4AI consortium and the SLICES-FR project, you will define and implement a reproducible experimental methodology for evaluating Net4AI mechanisms. You will design and develop automation software components (particularly via EnOSlib) for deploying distributed GenAI workloads. Finally, you will conduct experimental campaigns and actively contribute to scientific publications and open-source software for the project.

Consult the detailed job description

✔️ You have a perfect command of the Python language and collaborative development tools such as Git, continuous integration, and automated testing. You also possess solid knowledge of GNU/Linux systems, system administration, and datacenter networks, including routing and performance measurements.

✔️ You have significant experience in designing reproducible experiments and are capable of quickly acquiring skills in specific technologies like RDMA/RoCE.

✔️ You demonstrate great autonomy in conducting your work while showing exemplary scientific rigor and sharp critical thinking, particularly regarding the limitations of experimentation.

🇬🇧 You have excellent scientific English writing skills and communicate with ease, both written and orally, to report on your progress within a multi-partner consortium.

🎓 The ideal candidate will hold a Doctorate in Computer Science (or a related discipline) obtained less than 3 years before the hiring date.
