As part of Meta Security, our Insider Trust team is focused on identifying and responding to insider threats to data. The teams mission is to identify malicious use of otherwise legitimate access to data from people inside the company and respond to it before damage is done. We investigate across a broad spectrum of abuse including abuse of user data, intellectual property, and leaks of sensitive information. We collaborate with software engineering teams to build advanced detection capabilities and understand how abuse happens so that we can stay ahead of those who are interested in misusing their access. The Insider Trust team is looking for a highly motivated Security Engineer to build and improve internal tools and systems to detect malicious activities related to insider threats. Candidates are expected to analyze and monitor internal tools, hunt for insider threats against company data and infrastructure, and have the ability to carry out complex internal investigations from collection to reporting. As part of the role, this person will work side by side with our engineering teams to build advanced detection solutions to help keep systems and information safe, and partner closely with our Human Resources and Legal teams to carry out complex investigations.
