Systems Engineer

### 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.

The Systems Engineer will be a part of the Censys ARC (Advanced Research Collective) and will build and operate the pipelines and platforms that power Censys's threat detection and intelligence capabilities. This role will own the engineering behind static and dynamic file analysis at scale, and the graph-based systems that connect indicators, infrastructure, and actors into actionable threat intelligence. You'll work closely with threat researchers and analysts, turning detection and correlation requirements into production-grade systems.

For a systems engineer who's spent years wiring together detection pipelines and threat intel platforms, this role is the rare chance to build that infrastructure at the actual source of the data rather than downstream of it. Censys's internet-wide scan visibility means the enrichment and graph systems you're building aren't consuming someone else's feed, they're powering primary intelligence on global infrastructure and actors. You'd own meaningful technical surface end-to-end: static/dynamic analysis pipelines, YARA tooling, sandboxing, and threat graph modeling connecting indicators to actors, rather than being one contributor on a sprawling platform team. The ARC structure — sitting between engineering and research — means your systems get shaped directly by what threat researchers actually need next, not by a backlog several layers removed from the analysts using it. And for someone who wants to work at the edge of the field rather than behind i
