  Key Responsibilities
  • Translate business problems into well-defined machine learning and predictive modeling objectives.
  • 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 understanding of statistical analysis, probability, experimental design, and machine learning fundamentals.
  • Demonstrated experience building predictive models from raw data through final evaluation.
  • Deep practical expertise in regression and classification algorithms, including:
  • Linear and polynomial regression

  • 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.
