About the SnT...

SnT is a leading international research and innovation centre in secure, reliable and trustworthy ICT systems and services. We play an instrumental role in Luxembourg by fueling innovation through research partnerships with industry, boosting R&D investments leading to economic growth, and attracting highly qualified talent.

The Centre is rapidly expanding its research activities and is seeking highly motivated doctoral candidates who wish to pursue research in close cooperation with our partners. For further information you may check: and

We're looking for people driven by excellence, excited about innovation, and looking to make a difference. If this sounds like you, you've come to the right place!

Your Role...

The SnT is seeking a Postdoc (Research Associate) to support the research and development work within the SEDAN group. We seek a candidate with expertise and/or interest in the following relevant fields: machine learning, statistics, cybersecurity, networking, systems and micro-service architectures. While covering all these expertise fields is not mandatory, we expect the candidate to have strong interest in investigating all of them during the postdoc.

The candidate will the opportunity to work on a CORE project funded by the Luxembourg National Research Fund (FNR) to explore and validate theoretical research. The main objective of the project is to build a cybersecurity-oriented telemetry framework capturing and modeling causal dependencies in a microservice-based infrastructure to identify the complex inter-dependencies among events generated by applications, services, system and network communications.

Going beyond time-series model, the aim of the project is to progress on causal inference [1] modeling by combining probabilistic reasoning [2] and deep learning models [3]. The objective is thus to have a model capable to reason under uncertainty. Therefore, the postdoc will need to define a language for modeling purposes and with a first set of necessary algorithms for learning and inference from events. In a second stage, incremental learning will be considered to update model when drift is detected and merge multiple models. The main application is to discover dependencies in various logs in a micro-service environment (kubernetes) which will be used to track anomalies forward and backward in time. It is thus expected that the successful candidate will also deploy a small environment with existing tools (Prometheus, Loki, cAdvisor, Falco for example) and possibly develop new tools if needed.

In addition, the candidate will be also involved in project management, reporting and dissemination. The project is an academic project oriented but applied research. It is a unique opportunity to develop new concepts with a close collaboration. The project team is composed of the proncipal investigator (Dr. Jérôme FRANCOIS) and two research associates.

During postdoc, the candidate will have the opportunity to participate and propose other projects within the group. We are working on various topics related to applied ML and cyber-security, including applications and security of LLMs.
