Job description

The Senior Data Scientist at Chalhoub Group is responsible for designing, building, and continuously improving machine learning models that enable predictive, classification, optimization, and intelligent decision-making across multiple luxury retail business functions. The role focuses on ensuring model accuracy, robustness, fairness, and reliability through rigorous experimentation, feature engineering, hyperparameter tuning, evaluation, and continuous monitoring. The position involves implementing experiment tracking frameworks for reproducibility, defining and maintaining model performance metrics such as accuracy, F1 score, and AUC, detecting and mitigating model drift using statistical techniques including population stability index, and defining retraining strategies in collaboration with MLOps and platform teams. The Senior Data Scientist applies generative AI capabilities such as large language model fine-tuning, embeddings, and retrieval-augmented generation to support NLP and conversational use cases, while integrating models into production pipelines with Data Engineers, MLOps, and Product Managers. The role also requires documenting and versioning models and experiments for governance and auditability, linking model outputs to business success KPIs, and ensuring production readiness through MLOps practices using Azure ML and GCP Vertex AI within a large-scale omnichannel luxury retail ecosystem.
