Key Responsibilities:

• Develop machine learning, statistical, and graph-based models to analyze complex datasets
   

• Translate qualitative analytic requirements into quantitative models and software prototypes
   

• Produce data visualizations and dashboards to highlight key insights and trends
   

• Work with subject matter experts (SMEs) to extract meaningful features from structured and unstructured data (e.g., logs, metadata, databases)
   

• Prototype and evaluate multiple algorithmic approaches, selecting the best based on empirical performance
   

• Tune model hyperparameters and input features to optimize performance
   

• Validate models using standard evaluation techniques (e.g., cross-validation, ROC curves, confusion matrices)
   

• Develop experiments or simulated data when real-world data is unavailable
   

• Guide and oversee analytic teams throughout the development lifecycle
   

• Transition analytic prototypes to scalable, production-ready software
   

• Collaborate with software engineers and cloud developers to integrate analytics into broader systems
   

• Stay informed on emerging machine learning and AI techniques, and guide their practical application
   

• Lead development of automated systems to support mission-driven objectives
