Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.
We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.
We are hiring a Staff Attack Engineer to join the team behind our Rapid Response product. You will research and productize real-world exploitation techniques so customers can quickly understand whether newly disclosed or actively exploited vulnerabilities affect their environments—and what an attacker could do next.
You will focus on high-consequence vulnerabilities that are actively exploited, newly disclosed, or likely to generate significant attention - from CISA Known Exploited Vulnerabilities (KEVs) and Zero-Days to N-Days and emerging attack techniques. You will turn vulnerability research and attacker tradecraft into safe, repeatable, automated attack capabilities for the issues that are in the news, creating urgent customer concern, or most likely to affect the broader security community. This is not a traditional consulting or manual-pentesting role. Your work will help
security teams rapidly validate exposure, prioritize remediation, and verify that defenses are working.
We are a fully remote company, and this job may require up to 10% of travel to be successful.
Our commitment to diversity and inclusion means we strive to attract, develop, and retain a workforce that reflects the varied communities we serve. We believe that diverse perspectives drive innovation and strengthen our ability to create cutting-edge cybersecurity solutions.
