Great Hillis seeking a Data Management Specialist in the National Capital Region. The candidate will provide direct support to the Defense Security Cooperation Agency (DSCA) Chief Data Officer and Artificial Intelligence Officer (CDAO) to track and manage use case requirements for Security Cooperation (SC) data and identify opportunities to improve workflow, individual productivity, and time-to-market for data and analytic products. The candidate will support the implementation of DSCA data policy and processes to ensure policies are resulting in demonstrated business value. They should also recognize that there are two evolving overlapping data architectures: The emerging Case Execution Modernization Initiative (CEMI) federated data architecture that includes local reporting capabilities and transactional interfaces, and the enterprise reporting architecture currently in Advana that consumes data from legacy and modernized case development, execution, financial, supply chain, procurement, and acquisition systems. Additionally, the candidate will support the DSCA CDAO on issues related to data management and cross-functional business data integration.

Roles and Responsibilities include, but are not limited to:

The COE ensures data quality is measured, authoritative data is identified, and data models, labels, and standards are aligned for frictionless data sharing and algorithm development.

Develop supporting templates and tools to streamline the upload and maintenance of metadata capture and storage.

Support reporting of metadata using the Advana tools including the status of SCA data source pipelines and their data quality (scorecard for coverage, completeness, and timeliness), and use of SCA data sets by Advana dashboard applications.


  • Support training of Data Stewards regarding metadata responsibilities and use of catalog tools. Maintain the DSCA metadata metamodel and requirements and use it to measure the progress towards implementation in Advana in terms of scope and features.
