Security Manager

Horizon3.ai 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 seeking a highly motivated and experienced Security Operations Center (SOC) Manager to lead our internal SOC. We aren’t building a traditional, "stare-at-screens" SOC. As the SOC Manager, you are the architect of our defensive and offensive resilience. This is a high-impact, hybrid leadership role designed for a "builder" who thrives in the fast-paced environment of a scaling startup. You will lead a sophisticated team that doesn't just monitor alerts but actively engineers a self-healing security ecosystem.

You will bridge the gap between technical execution and strategic risk reduction. Your focus is to integrate AI/ML-enabled detection, hyperautomation, dynamic defensive controls, and continuous offensive testing into a unified operation that scales seamlessly with our business.
