This blog provides a brief description of four technical positions that are open here at Tenable: Vulnerability Research Engineer This position is ideal for those who like to research and test software vulnerabilities. The results of your research will present themselves as Nessus and PVS plugins, which are small scripts that are able to detect vulnerabilities. In this role, you will accurately test for vulnerabilities by manually configuring vulnerable targets in a virtual environment, analyzing the system or application to reliably understand how the vulnerability is exploited and then developing a method to test for the vulnerability with credentialed or uncredentialed access. We are looking for people with strong programming skills (knowledge of a scripting language, regular expressions, functions and source code analysis), familiarity with system configurations in operating systems, applications or network devices and in-depth knowledge of TCP/IP protocols, Linux/Unix internals and Windows internals.
