Job description

The Government of Ontario is embarking on a large Data &AI transformation initiative. Core to the transformation is the enablement ofthe Ontario Data Platform (ODP), which is being developed as the enterprisetechnology ecosystem for everything Data & AI. ODP is a modern ecosystem ofdata solution consisting of data ingestion technologies, storage, processingand visualization as well as solutions related to data governance, quality,marketplace, etc. ODP will initially serve all internal government clusters,ministries and program areas, but also external agencies in the future. We arelooking for a data scientist to support various initiatives related to theplatform as well as the execution of use cases to support the needs of variousbusinesses within the government.
