• Collect, clean, transform, and analyze structured and unstructured data from multiple sources. 

• Perform exploratory data analysis to identify trends, relationships, anomalies, biases, and data-quality issues. 

• Develop predictive models from scratch, including data preparation, feature engineering, training, validation, testing, and optimization. 

• Build and apply regression models for forecasting, estimation, risk scoring, pricing, demand prediction, and related use cases. 

• Build and apply classification models for segmentation, fraud detection, churn prediction, recommendation, anomaly detection, and other decision-support applications. 

• Select appropriate algorithms based on the problem type, data characteristics, business requirements, interpretability needs, and operational constraints. 

• Compare baseline, linear, tree-based, ensemble, and other appropriate modeling approaches. 

• Tune model hyperparameters and use appropriate cross-validation strategies to improve generalization. 

• Experience building and deploying AI solutions using Natural Language Processing (NLP), Computer Vision, and sequence modeling techniques for text, image, video, and time-series data. 

• Strong knowledge of deep learning architectures including RNNs, LSTMs, GRUs, CNNs, and Transformer-based models, with hands-on experience using TensorFlow or PyTorch. 

• Ability to evaluate, optimize, and explain AI model performance, including model accuracy, robustness, bias detection, feature interpretation, and production monitoring. 

• Evaluate model performance using relevant metrics such as RMSE, MAE, R, accuracy, precision, recall, F1 score, ROC-AUC, PR-AUC, log loss, calibration, and lift. 

• Analyze model errors and identify opportunities for improving data quality, features, sampling strategies, and model assumptions. 

• Assess model robustness, explainability, fairness, stability, and sensitivity to changing data patterns. 

• Clearly communicate the rationale behind model selection, including why a particular model was chosen over alternatives. 

• Explain technical results, assumptions, limitations, and trade-offs to product managers, business leaders, and other stakeholders. 

• Document analytical methods, data sources, assumptions, experiments, model decisions, and results. 

• Collaborate with data engineers, software engineers, product teams, domain experts, and business stakeholders to operationalize models. 

• Support model deployment, monitoring, retraining, and continuous improvement in production environments. 

• Stay current with developments in machine learning, statistical modeling, AI techniques, and responsible AI practices. 

Required Qualifications 

• Bachelor's or master's degree in Data Science, Statistics, Mathematics, Computer Science, Engineering, Economics, or a related quantitative discipline. 

• 3+ years of professional experience in data science, machine learning, predictive analytics, or a closely related field.

• Strong SQL skills and experience querying, joining, aggregating, and analyzing data from relational databases. 

• Experience working with missing data, outliers, imbalanced classes, categorical variables, high-cardinality features, and data leakage risks. 

• Ability to select and justify appropriate evaluation metrics based on business objectives and model use cases. 

• Experience explaining model behavior using techniques such as feature importance, partial dependence, SHAP, coefficients, permutation importance, or related methods.
