Wireless Security Engineer

Job Description

This team leverages extensive expertise in hardware, software, network, and RF communications to identify and evaluate cyber vulnerabilities in critical military assets, threat systems, and critical infrastructure. The Division specializes in RF/wireless embedded devices such as radios, modems, routers and embedded controllers found in mission critical military systems and networks, and throughout commercial industry. They performs Red and Blue team activities focusing on vulnerability discovery and the development and demonstration of multi-domain techniques to gain unauthorized access to and/or exploit information networks, while protecting US Government assets from the same. These efforts identify weaknesses and help ensure that mitigations are effective. This specific job posting is for the Colorado Springs Field Office, which services the military and intelligence developmental and acquisition organizations along the Colorado Front Range, including the United States Space Force units (Space Systems Command, Space Warfighting Analysis Center, Strategic Space Defense Program, etc.), U.S. Space Command, Missile Defense Agency, Air Force TENCAP, and the United States Air Force Academy.

Job Purpose Wireless security engineers will develop integrated cyber and electronic warfare capabilities to conduct information operations against threat systems, and will support Test and Evaluation activities to help protect US systems from similar attacks.

Key Responsibilities -Develop and demonstrate over the air techniques to gain unauthorized access to and/or exploit wireless communication networks. Develop and demonstrate mitigation techniques to protect systems. -Develop SDR algorithms to (1) reverse engineer signals, (2) demodulate and decode RF signals and (3) to generate similar RF signals -Research capabilities, implementation methods and security features of device under test to help in determining functionality and potential weaknesses. Commonly evaluated devices include communications devices such as radios, modems, and routers. -Perform tests to determine susceptibility to jamming, spoofing signals and other countermeasure techniques -Primary author of technical reports/presentations for projects of moderate/high complexity. Compile report input from other researchers and prepare final report deliverable.
