## Description

* We are seeking a highly skilled Data Scientist with proven expertise in Graph Neural Networks (GNNs) and Graph Machine Learning to lead the design, development, and implementation of graph-based AI models as part of a strategic Proof of Concept (POC).
 * The GNN architecture is the core of this engagement and, therefore, candidates must demonstrate prior hands-on experience building, training, evaluating, and deploying graph-based machine learning solutions.
 * General Data Science, Machine Learning, or Deep Learning experience alone will not be considered sufficient., * Design, build, and optimize Graph Neural Network (GNN) models for complex business problems.
 * Develop graph-based solutions for:
 + Link Prediction
 + Node Classification
 + Recommendation Systems
 + Network Analysis
 + Knowledge Graph Analytics
 + Fraud Detection
 + Entity Resolution
 * Build scalable graph data pipelines and feature engineering workflows.
 * Work with large-scale graph datasets and graph databases.
 * Conduct model evaluation, experimentation, and performance optimization.
 * Collaborate with domain experts, architects, and engineering teams to deliver production-ready solutions.
 * Present technical findings and solution recommendations to stakeholders.
