Role: Full Stack Java Developer

Description: The Investment Data Warehouse (IDW) was created to serve as the Single Source of Truth (SSoT) for Investment Book of Record (IBOR) data. As the SSoT for IBOR data, the IDW must ingest data from a variety of internal and external sources, validate the data to ensure high quality and store data in a format optimized for distribution to end consumers. Since the initial inception of the IDW, both the business and technology landscapes have gone through evolutionary changes. With these changes the current implementation of the IBOR is not expected to be able to continue to adequately support the changed consumer needs. To adequately support the needs of consumers, scale for the future, respond quickly to the rapid pace of change in both business and technology and be aligned with the latest data policies, future implementation of the IBOR SSoT will be aligned with the Enterprise Data Architecture strategy for SSoT platforms and conform to the latest Enterprise Data Management policies.
