5+ years of software development experience using Java, C, C++, or other programming or scripting languages, including experience designing and developing host based and network based scanning tools.
Experience with Security Content Automation Protocol (SCAP) based tools and specifications.
Experience installing, configuring, testing, deploying, operating, and maintaining enterprise network based scanning and reporting tools such as Trellix/ESS, ACAS, RedSeal, Evaluate STIG, SteelCloud ConfigOS, and STIG Manager.
Extensive experience hardening modern Unix operating systems, such as Oracle Solaris 10/11 and RHEL, as well as Microsoft Windows environments using Security Technical Implementation Guides (STIGs).
