RF Engineer III

Description Naval Information Warfare Center (NIWC) Atlantic is one of the major organizations responsible for the research, development, testing, and evaluation (RDT&E) of new and emerging technologies to enhance and increase the capabilities of Naval SIGINT programs (SSEE/CCOP). This support includes but is not limited to; research and identification of innovative technology, requirements analysis, testing and demonstration, technical writing, representation at S&T/R&D conferences, training, procurement, configuration management, production, transition support, drafting and repair. This support, ultimately, is designed to ensure the deployed Navy sensors are capable of achieving success against emerging technology from our Nation's adversaries.
