LOCATION: VANCOUVER, BC
This role is part of a large, multi-year enterprise implementation focused on establishing a unified, high-confidence approach to identity resolution and advanced search across core data platforms. The program is introducing new clustering, survivorship, and search capabilities to replace fragmented legacy approaches, enabling accurate matching, reconciliation, and discovery of customer and organizational records at scale. These capabilities are foundational to data quality, operational efficiency, and downstream system reliability.
The Senior Data Scientist implements clustering logic, survivorship workflows, and advanced search services that must perform reliably under high volume and complex matching scenarios. The services built in this stream are consumed by multiple teams and systems, making correctness, performance, and maintainability critical. While initially assigned to this flagship implementation, the clustering algorithms, search services, and engineering patterns delivered by this role are intended to become reusable assets across future transformation initiatives, positioning the Senior Data Scientist as a key contributor to long-term identity and search capabilities within the consulting practice.
