Desired Skills and Experience:

• Recent experience with the Sponsor’s suite of applications for repository and search services, enabling users to efficiently search and find critical information.
• Familiarity with the Sponsor’s profile and alerting services, including a "prospective search" tool that identifies and alerts users to relevant data streams.
• Experience working with the Sponsor’s discovery and recommendation services, helping users uncover data they might not have known about through content-based filtering.
• Expertise in the Sponsor’s Pre-NLP processing pipeline, which removes boilerplate text, portion marks, and non-narrative content to improve data quality.
