Job Description

Your Career

We're looking for a Staff Security Researcher for Cortex Xpanse's Security Research Engineering team. You will be responsible for the creation, validation and deployment of vulnerability signatures and protocol payloads which will be used by our scanning infrastructure to understand what vulnerabilities are exposed across customer networks. You will also be responsible for creating new policies, which encode risky device configurations as code that is run over observations from our global scanning data. You will be a key member of a team that proactively sources vulnerabilities and misconfigurations from newly discovered CVEs and responds to Xpanse customer requests.

Our mission is to find risks online and protect the world's largest organizations from malicious software and hackers. Expanse's Internet intelligence platform collects petabytes of Internet data, leverages artificial intelligence to discover "unknown unknown" risks for customers, and delivers those insights via a SaaS web application. On this team, you will directly contribute to our mission by defining and delivering on Expanse's technical roadmap.

Your Impact

Contribute to Xpanse's critical vulnerability response by implementing the necessary vulnerability signatures and payloads to detect presence of critical CVEs while effectively communicating with the Xpanse team, across the Cortex business unit, and across Palo Alto Networks
Research trending threats and develop proof of concepts to detect presence of confirmed and inferred vulnerabilities
Research and develop fingerprints that can help Xpanse identify and structure more and more types of services running on the global Internet
Proactively add customer-requested policies and implement protocol payloads while minimizing false positives & false negatives
Research emerging vulnerability threats on the global Internet and contribute to Cortex Research blogs/publications

Familiarity with one or more programming languages (Java, Python, Go, Bash)
Ability to concisely communicate complex subject matter to technical and non-technical audiences

Additional Information
The Team

Cortex Xpanse helps protect some of the world's most important organizations by finding risks on the Internet that no one else can find. Our security research teams are at the core of our products and are responsible for building security detections for our products that allow customers to turn trillions of Internet data points into critical cybersecurity insights. We are constantly innovating — challenging the way we, and the industry, think about cybersecurity. Our engineers don't shy away from building products to solve problems no one has pursued before.

We define the industry instead of waiting for directions. We need individuals who feel comfortable in ambiguity, excited by the prospect of a challenge, and empowered by the unknown risks facing our everyday lives that are only enabled by a secure digital environment.

Our Commitment

We're trailblazers that dream big, take risks, and challenge cybersecurity's status quo. It's simple: we can't accomplish our mission without diverse teams innovating, together.
