Sales Engineer (Mid-Senior Level) - Cybersecurity

Horizon3 is a fast-growing, remote cybersecurity company dedicated to helping organizations proactively identify, fix, and verify exploitable attack vectors before criminals exploit them. Their flagship product, NodeZero™, delivers autonomous pentests and security assessments scalable across internal, external, cloud, and hybrid environments. The platform is trusted by organizations of all sizes, from educational institutions to government agencies and Global 100 enterprises.

The company is built by a fusion of former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners. Their mission is to address common security challenges, including ineffective tools, alert fatigue, blind spots, and the high cost of hiring external consultants.

As a remote-first company, Horizon3 requires a minimum 25Mbps consumer-grade broadband connection.

About the Role

Horizon3 is redefining cybersecurity defense with their autonomous platform, NodeZero, which helps companies proactively mitigate vulnerabilities before attackers exploit them.
