The ideal candidate will be comfortable working across the full data science lifecycle, from exploratory analysis and model development to building scalable data pipelines and deploying production-ready solutions.

Key Responsibilities

• Analyze large operational datasets to identify trends, anomalies, outliers, and risk indicators.
• Develop analytical solutions involving anomaly detection, clustering, segmentation, and risk-scoring methodologies.
• Build and evaluate supervised machine learning models using historical and labeled datasets.
• Perform feature engineering using both structured and unstructured data sources.
• Design and execute model evaluation frameworks, including precision, recall, false-positive, and false-negative analysis.
• Collaborate with domain experts to integrate analytical outputs into operational workflows and business processes.
• Build and maintain scalable data processing and feature engineering pipelines.
• Develop and deploy production-ready models and scoring solutions integrated with applications used by delivery teams.
• Conduct exploratory data analysis to uncover opportunities for workflow optimization and automation.
• Support the adoption of Large Language Models (LLMs) and other AI techniques alongside traditional statistical and machine learning approaches.
• Develop reusable analytical frameworks, assets, and components that can be leveraged across multiple government agency engagements.
