About The Position

Censys’ mission is to be the one place to understand everything on the internet. Frustrated by the lack of trustworthy Internet intelligence, we set out to create the industry’s most comprehensive, accurate, and up-to-date map of the Internet. Today, Censys delivers real-time Internet intelligence and actionable threat insights to global governments, over 50% of the Fortune 500, and leading threat intelligence providers worldwide. Censys is looking for a Product Detection Engineer to join our Detection and Response team within our Research organization. This is not a typical corporate detection engineer role. This role will work within the Censys dataset to fingerprint hardware, software, and services in the Censys Internet Intelligence Platform, as well as to develop detections for misconfigurations and vulnerabilities. In a number of cases, the detection engineer will work with members of our research team to identify adversary infrastructure, discover anomalies, interpret patterns and limitations of our rules engine, etc.

Responsibilities

Develop custom fingerprints against Censys scan data to enrich, contextualize, and uncover risks in services and infrastructure running on the Internet.

Coordinate with our Go-to-Market and Sales teams to facilitate researching and fingerprinting of emerging vulnerabilities, threats, and high-priority detections.
