ClearanceJobs Tech Stack

Career network matching security-cleared professionals with defense employers

Defense and Space Manufacturing Centennial, CO 51–200 employees Founded 2002 Public Company

ClearanceJobs runs a job marketplace connecting cleared national-security professionals with defense-industry recruiters. Its job-post stack is unusual for a career site: reverse-engineering tools (Ghidra, IDA Pro, Radare2, JTAG) alongside Fortran, MATLAB and STK. Paired with projects in offensive attack content and automated attack execution, this suggests the listings reflect cleared client-side engineering work. Hiring is minimal and senior, engineering only.
