Key Responsibilities

• Analyze business problems and stakeholder requirements to frame data science use cases, define objectives, success metrics, assumptions, and constraints.
• Acquire, profile, and integrate structured and unstructured data from enterprise sources; assess data quality, completeness, consistency, and suitability for the problem at hand.
• Perform exploratory data analysis (EDA), feature engineering, preprocessing, and visualization to uncover patterns, validate hypotheses, and prepare data for modeling.
• Determine the appropriate analytical or machine learning approach based on the business problem and data characteristics, including regression, classification, clustering, time-series, or rule-based methods when ML is not warranted.
• Develop, test, and compare candidate models using standard data science practices such as train/validation/test splits, cross-validation, performance measurement, error analysis, and hyperparameter tuning.
• Document methodology, assumptions, model performance, and limitations; communicate results, recommendations, and business implications clearly to technical and non-technical stakeholders.
• Deploy and operationalize models and data pipelines in collaboration with data/platform teams; ensure outputs are production-ready, scalable, monitored, and maintainable.
• Build and support downstream reports, dashboards, and visualizations that translate model outputs and analytics into actionable business insights.
• Monitor model health, data drift, and business impact after deployment; fine-tune models, features, or pipeline logic as needed to sustain performance.
• Follow established standards for coding, documentation, governance, reproducibility, version control, and responsible use of enterprise data and AI/ML methods.

Additional Job skills

• Preferred technical skills: Python, SQL, PySpark or Spark, machine learning libraries/frameworks, statistical analysis, data wrangling, and visualization tools such as Tableau or Power BI.
• Experience with Databricks or comparable cloud analytics platforms, model/pipeline operationalization, and production data workflows is preferred.
• Knowledge of deep learning and NLP/LLM concepts, techniques, and practical applications is preferred to support advanced text analytics, generative AI, and emerging AI/ML use cases.
• Familiarity with experiment design, model evaluation metrics, feature selection, and monitoring for drift or performance degradation is preferred.
• Working knowledge of data warehousing concepts, dashboard design, and communicating insights through visualization and storytelling is preferred.
• Experience with version control, reusable code development, and documentation of data science workflows is preferred.
• Bachelor’s or Master’s degree in Computer Science, Information Science, Statistics, Mathematics, or a related quantitative field.
• Typical experience: approximately 2–5 years of relevant experience in data science, advanced analytics, or machine learning solutions delivery.
