Director, Engineering, Proactive Offense

Get to Know Us

Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, 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 IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and 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.

As a remote first company, we require minimum 25Mbps consumer grade broadband connection.

What You'll Do

As Director of Software Engineering – Offensive Security, you’ll lead the strategy, design, and development of NodeZero’s offensive capabilities, driving innovation in autonomous attack content, exploit development, and platform scalability. You’ll manage multiple engineering teams, balancing deep technical expertise with product and organizational leadership.

This role sits above our offensive engineering leaders and pods (Attack Engineering) and will play a key role in scaling the offensive product organization as we continue to expand NodeZero’s reach and sophistication.
