An Unwavering Force for National Security

Sr. Data Engineer

Intelligence/Intel Community

Reston, VA
ID: 503-383

Core4ce has an opportunity with a mission critical IC Sponsor for a Sr. Data Engineer Position. This Sponsor organization plays a significant role in the highly optimized mission-ready data conditioning and delivery systems in support of mission analytics. A Full Scope Polygraph is required for this position, no exceptions. 

The ideal candidate supports critical mission objectives in near real-time - designing, engineering, and maintaining systems that accept raw streaming data feeds from a wide variety of sources. Because raw content itself is of nominal use to the mission, candidates are entrusted by the mission to build processes that extract, transform, and load data into downstream applications. These downstream applications are vital to the mission. But their value is compromised without continuous data updates. Candidates keep the data flowing to mission users, 24x7. Interested candidates will also develop dashboards and automated alerting mechanisms to monitor data feeds. Mission success depends on flagging data flow failures and restoring data to mission users and systems, with maximum urgency and minimal delay. 




Candidate will design and develop complex new software products or make significant enhancements to existing software. The ideal candidate is a hands-on developer with significant experience in building modular, reusable services and features.  Candidate must have expertise in a modern service-oriented architecture and must be familiar with working on an Agile team environment with little to no supervision.  Successful candidates embody a passion for continuous improvement and innovation.
