About the Job

Requirements

  • Be a final-year engineering-school student specializing in artificial intelligence, software development, or cybersecurity, and seeking a six-month internship to complete the course of study.
  • Have strong proficiency in deep learning and graph theory.
  • Have strong proficiency in Python, artificial-intelligence and graph libraries including PyTorch, PyTorch Geometric, and Scikit-learn, and code/version-management tools such as Git.
  • Be able to synthesize scientific papers and have scientific English proficiency at C1–C2 level.
  • Have cybersecurity knowledge, including network protocols such as TCP/IP and DNS and attack mechanisms such as DDoS, port scanning, and lateral movement.
  • Have knowledge of Graph Representation Learning, Graph Neural Networks, and generative AI.

Responsibilities

  • Study variants of Graph Neural Networks applied to cybersecurity, including GCN, GAT, GraphSAGE, dynamic GNNs for temporal graphs, graph autoencoders for unsupervised learning, and self-supervised learning approaches such as GraphIDS.
  • Identify the strengths and limitations of current approaches, including scalability on massive graphs and handling heterogeneous and dynamic graphs.
  • Propose an intrusion-detection module by modeling and preparing data, implementing architectures, and testing different learning strategies.
  • Apply models to public network-intrusion datasets covering enterprise networks, IoT networks, and telecommunications infrastructure networks.
  • Develop the software components needed to demonstrate the use case, evaluate it, and benchmark it.
  • Write the internship report.
