Company Background 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. Location: This position is remote within the United States or Canada. At Censys , we’re on a mission to provide best in class internet visibility and intelligence to the global security community. Our platform helps security teams uncover hidden threats, gain actionable insights, and build proactive defense strategies.

We’re constantly pushing the boundaries of what’s possible to help our customers see and secure the internet more clearly than ever before. Role Summary: Censys is seeking a Staff Application Security Engineer to join our Infrastructure and Operations Platform (SRE) team. In this role, you’ll own the application security strategy for how Censys builds and ships software — designing the secure paths, guardrails, and automation that let our engineers develop and deploy quickly, confidently, and securely.

As a security company, we hold ourselves to the standard we help our customers achieve; this role is central to making that real. We expect all of our employees to consider customer happiness as our primary goal and to come to work every day eager to learn and educate, helping to make us a better organization every day.

For all other US locations, the expected salary range for this position is $172,000 USD – $216,000 USD, plus bonus eligibility and equity.
