Data Scientist

Data Scientist

Work Location: Qatar

Core Responsibilities:

• Design, build, and optimize predictive models and machine learning algorithms using structured and semi-structured data.
• Perform data preprocessing, feature engineering, and model selection independently.
• Build and maintain automated model pipelines including training, validation, scoring, and monitoring.
• Implement model drift detection, retraining logic, and performance diagnostics.
• Conduct code-based model explainability (e.g. SHAP, LIME), support documentation for governance review.

Expertise Required

• Advanced proficiency in Python (Pandas, NumPy, Scikit-learn, XGBoost, LightGBM)
• Strong command of SQL and handling large datasets (via warehouse or lake)
• Experience deploying models using MLflow, Airflow, Docker, or similar tools
• Familiarity with model performance metrics (ROC AUC, F1, lift/gain, etc.)
• Hands-on in training and evaluating models for binary classification, multi-class, regression, or time series
• Exposure to deep learning (PyTorch or TensorFlow) for advanced use cases
• Working knowledge of embeddings, vector stores, or text-based models
