This role is best suited for someone with a blend of Data Engineering (60 70%) and Data Science (30 40%) skills. The focus is on Oracle migration, data quality, SQL/Python development, statistical analysis, and cross-functional collaboration, rather than machine learning. The team is supporting TD's migration from SAS-based systems to Oracle for AML/financial crime monitoring, and is looking for contractors to support this transformation project. Core Oracle migration and implementation work runs until April 2027, with interim monitoring work expected to be busiest until approximately October 2026, with ongoing support afterward. The hiring manager is looking for a full-stack data scientist who combines Data Science, Data Engineering, Data Quality, Data Exploration, and Statistical Analysis capabilities. The exact job title is not important candidates can come from Data Scientist, Data Engineer, or Data Analyst backgrounds if they have the right experience. Fast learners with strong technical fundamentals and migration experience will be highly competitive.

Perform data quality validation, data cleansing, data stitching, and data integration
Build data engineering capabilities for combining multiple data sources
Support Oracle implementation (MVP 2) by validating data and preparing scenarios
Conduct transaction segmentation and initial threshold setting for AML monitoring scenarios
Monitor production performance, alert volumes, and suspicious transaction reports (STRs) after implementation
Analyze impacts when unusual alert patterns occur
