Senior Customer Success Associate

Horizon3 is a fast-growing, remote cybersecurity company dedicated to enabling organizations to proactively find, fix, and verify exploitable attack vectors before criminals exploit them. Our flagship product, the Node Zero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. Node Zero 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/Sec Ops teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers and operators, and formerly frustrated cybersecurity practitioners. We are committed to solving common security problems including ineffective security tools, falsepositives, alert fatigue, blind spots, “checkbox” security culture, cybersecurity skills shortages, 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.

The Digital Customer Success Manager/Associate plays a critical role in helping customers realize value from Node Zero through a proactive, scalable, and digital-first customer success motion.

This role combines customer partnership, cybersecurity fluency, strong written communication, data-informed prioritization, and repeatable engagement programs. Depending on experience, this position may be hired at the Customer Success Associate or Customer Success Manager level.

Both levels are expected to communicate clearly, learn technical concepts quickly, manage customer work with discipline, and help customers take meaningful action. The Customer Success Manager level operates with greater independence, owns more complex programs and customer situations, and contributes to improving the Digital Customer Success operating model.
