Barbaricum is seeking a Senior Data Scientist to support the Department of Defense’s Chief Data and Artificial Intelligence Officer (CDAO) in accelerating the DoD’s adoption of data, analytics, and AI. The Search Portfolio serves the fundamental need to accelerate decision advantage through information accessibility, information retrieval and insight extraction. The Portfolio will sustain the GAMECHANGER, Contract Search, and JBook Search applications on the Advana platform as the platform upgrades and evolves. This role will be essential for the program and mission as it delivers specialized AI and machine learning capabilities crucial for handling, analyzing, and optimizing large and complex datasets, which are integral to defense and intelligence functions.

 

Responsibilities:

Designs, configures, develops, tests, and supports informatics and data science solutions for a wide array of technical use cases. Collaborate with cross-functional teams, including data scientists and software engineers to integrate AI solutions developed by other elements of CDAO or the DoD community into Search Portfolio products when appropriate. Optimize AI models for performance, scalability, and efficiency, leveraging cloud-based resources and distributed computing frameworks, specifically Apache Spark/Databricks. Ability to adapt code base to also run using GPU enabled Kubernetes clusters. Stay updated on and contribute to the latest advancements in AI research, applying new findings to improve Search Portfolio products. Manage the lifecycle of AI/ML components used in Search Portfolio products from research and development to deployment and optimization. Applies analytical methodologies to diagnose data-related challenges, implement solutions, and evaluate performance; Documents and presents requirements, design alternatives, and findings to team members and clients. Ability to develop strategic, baselined, data modeling processes; ability to accurately determine cause-and-effect relationships; and experience with integrated development environments, data integration, data visualization, data mining, and analysis tools.
