Horizon3.ai 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 autonomous security platform, NodeZero™, uses AI and automation to continuously validate security posture across internal, external, cloud, and hybrid environments, helping enterprises reduce risk and strengthen defenses at scale.
We’re a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We’re committed to solving common security problems: ineffective tools, false positives and alert fatigue, blind spots, “checkbox” security culture, cybersecurity skills shortages, and the high cost and long lead time of traditional consulting.
We are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results.
We are seeking a Senior Manager, Public Relations & Communications (P5) to build and lead a high-impact PR and communications engine that elevates Horizon3.ai’s brand, strengthens our market narrative, and accelerates demand.
In this role, you will own end-to-end press relations, corporate communications, and executive visibility for Horizon3.ai. You will develop and execute integrated communications strategies that position our executives and subject-matter experts as category-defining voices in offensive security, AI-driven automation, and modern cybersecurity operations.
You will work closely with Marketing, Executive Leadership, Product, Customer, and People teams to drive cohesive storytelling across press, analysts, social, speaking opportunities, and events. This is a highly visible, strategic role with direct impact on brand awareness, mindshare, and pipeline.

Manage inbound media inquiries and coordinate briefing prep, talking points, Q&A, and follow-ups for executives and SMEs.
Build and maintain a media list, coverage tracker, and measurement framework to report on velocity, sentiment, share of voice, and message pull-through.
Partner with the CEO, CMO, CPO, CTO, and other leaders to shape executive thought leadership platforms, including bylines, op-eds, speaking topics, and social content.

Partner closely with Field Marketing and Events teams to maximize media and executive visibility at strategic conferences and summits.

Serve as a strategic advisor to leadership in sensitive situations, helping assess risk, craft messages, and coordinate internal and external responses.

Use data and feedback from Sales, Leadership, and Marketing to optimize storytelling, messaging, and targeting.
Continuously refine processes, playbooks, and templates to increase speed, quality, and repeatability.
