• Strong expertise in classical/statistical ML, forecasting, optimization, and deep learning.
• Experience with NLP, Computer Vision, graph-based features, or knowledge graphs is a plus.
• Strong Python, SQL, and experience with scikit-learn, PyTorch/TensorFlow, MLflow, or Weights & Biases.
• Strong knowledge of hypothesis testing, confidence intervals, and causal inference.
• Familiarity with fairness/bias evaluation and explainability tools such as SHAP and LIME.
• Strong communication skills with the ability to explain technical concepts and model trade-offs to business stakeholders.
• Ability to defend modeling decisions and collaborate closely with engineering and architecture teams.

Responsibilities

• Own model development, experimentation, evaluation, and production readiness.
• Develop forecasting, optimization, recommendation, decision-science, and ML models.
• Perform feature engineering, EDA, and statistical analysis to identify meaningful patterns.
• Design rigorous model evaluation, validation, and testing frameworks.
• Validate model performance, fairness, and bias before go-live.
• Manage experiment tracking, datasets, and model reproducibility using tools such as MLflow/W&B.
• Present model results, trade-offs, and uncertainty to business stakeholders.
• Collaborate with ML Engineers and Architects to productionize models.
• Lead complex decision-intelligence engagements when required.
• Mentor junior Data Scientists and ML Engineers.
