Geospatial Data Engineer

Date: Sep 21, 2022

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 7635 

Overview:

The Geospatial Science and Human Security Division (GSHSD) is seeking a geospatial data engineer within the Location Intelligence group. This position is within the Division’s Human Dynamics section and part of the National Security Science Directorate. The Location Intelligence Group performs ground-breaking research into place-based knowledge extraction, narrative analysis, and geosocial data discovery. Leveraging primarily “non-traditional” geospatial data sources such as volunteered geographic information (VGI), internet of things (IoT) data, and telemetered sensor sources, and harmonizing with commercial and open data sources, the Location Intelligence group delivers novel approaches and technologies for describing places, points of interest, events, activities, and populations, as well as the patterns of interaction among the three. The group’s dynamic content portfolio addresses the timely need to broaden research in spatial data curation, multi-scale land-use modeling, generating higher-level features from ground photo imagery, disinformation detection, network spatialization, narrative analysis, and transformation to describe the landscape and patterns of activity within it, using novel and non-traditional data and theoretical techniques.

 

This position involves developing and deploying scalable geospatial applications supporting the group’s R&D portfolio. The position’s focus includes architecting geospatial services, working with the CI/CD deployment teams, performing stress testing of deployed services and applications, cloud-to-premise interfacing, and distributed computing to deploy real-time geospatial intelligence applications. The individual will collaborate with other scientists in developing transformative technologies that address these challenges through teaming and collaborative efforts. The work will involve harvesting and processing several hundred disparate data sources from all around the world. These sources contain text, sensors, ground-level imagery, social media, trajectory, and travel data, among others. Enabling this data for purposeful use requires designing and architecting RESTful services and distributed failover backend services. To confidently run them, individuals are required to have a good background in the following initiatives: Architect and design Spring boot and Java Application, open-source exploitation; geospatial OGC services architecture and development, Java and object-oriented concepts, application server failover and load balancing, and geospatial formats such as GeoJson and GeoPackage; and a working knowledge of GIS methodologies.

 

Our commitment to diversity:  

As we strive to become the world’s premier research institution in the sciences and technologies that underpin critical national security missions, we are committed to creating an inclusive environment that highly values a diverse workforce.  We recognize that breadth of perspectives, insights, and experiences is necessary to drive innovation and discovery mission-critical to national security sciences.  Our commitment extends beyond our workforce to the next generation of researchers with STEM education outreach that seeks to engage a diverse range of students.
