• Apply regression techniques including Ridge, Lasso, and polynomial regression, and leverage interpretability tools such as SHAP values
• Work with large-scale data sets and frameworks including Hadoop, Spark, PyTorch, TensorFlow, or similar technologies
• Collaborate with engineering teams to integrate analytical models into production systems through APIs and data pipelines
• Create clear, compelling data visualizations using Python or R libraries such as Matplotlib, Seaborn, ggplot2, and Plotly
• Partner with stakeholders across business units to identify opportunities for data-driven decision-making
• Maintain a strong understanding of data architecture, warehousing, and governance using tools such as Pig, MapReduce, Spark, and Hive
• Mentor junior data scientists and contribute to best practices in model development and deployment

Education:

• Masters degree in a related field or the equivalent through a combination of education and related work experience

Work Experience:

• Minimum of 5 years of professional experience in data science or a related field
• Proven expertise in applying advanced analytical techniques, including:
  • Ensemble algorithms (e.g., bagging, boosting, GBM, random forest)
  • Winner-take-all methods (e.g., SVM, KNN)
  • Regression techniques (e.g., Ridge, Lasso, Polynomial, SHAP)

• Strong proficiency in Python or R, with a focus on applied theory and model interpretability
