Role Summary:

Security researchers have a strong technical background and excel at creative problem solving. You rely on your expertise to guide your approach to investigations, including generating your own research ideas. This role will help provide the engineering teams with the information needed to provide better coverage, derive deeper insights from our data, and help surface these improvements directly to our customers.

One week you might perform detailed analysis of hosts vulnerable to a particular CVE, and the next week you may be asked to investigate which endpoints we need to scan to improve classification of networking devices.

• Partner with Research and Product to deliver new security prototypes to customers as well as to guide where we should develop new products.
• Inspect, mine, transform, and analyze large datasets to identify patterns and trends to further support engineering efforts such as predictive modeling of scan targets, software and hardware identification, vulnerability detection, threat actor identification, and more.
• Work closely with multiple engineering teams to help inform technical decision making in regards to providing better coverage, context, and insights.
• Assist in data classification and dataset interrogation using techniques such as entity and identity resolution, cluster, data gap analysis, and others.
• As needed, serve as a public face for Censys by sharing knowledge and expertise around how Internet-wide security trends impact our customers across the public and private sectors, as well as the broader global security community
• Open to using AI to amplify their skills and strengthen their work - demonstrating curiosity, a willingness to learn, and sound judgment in applying AI responsibly to improve efficiency and impact
