Senior Product Marketing Manager, Internal & Cloud Pentesting

Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company on a mission to shift the advantage from attackers to defenders. Our flagship product, the NodeZero® platform, autonomously executes real attack techniques in production—safely, without agents or disruption—to help organizations find exploitable weaknesses, fix what matters most, verify remediation, and continuously prove their resilience. NodeZero helps organizations understand risk across their internal networks, external attack surface, cloud environments, identities, data, and web applications. Customers use the platform to replace assumptions with evidence: what an attacker can actually exploit, how an attack can move through the environment, what the business impact could be, and whether a fix truly worked. We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We are committed to solving common security problems including ineffective tools, false positives, alert fatigue, blind spots, checkbox security culture, cybersecurity skills shortages, and the time and expense of point-in-time manual assessments. Collectively, we are a team of learn-it-alls committed to respect, collaboration, ownership, and results. As a remote-first company, we require a minimum 25Mbps consumer-grade broadband connection.

We are looking for a Senior Product Marketing Manager to own the go-to-market engine for NodeZero’s Internal and Cloud Pentesting portfolio. This role will shape how Horizon3 explains, launches, sells, and expands capabilities that help customers safely validate attack paths across internal infrastructure, identities, cloud environments, and hybrid estates. You will report directly to the VP of Corporate & Product Marketing and partner closely with Product, Engineering, Attack Research, Sales, Solutions Engineering, Customer Success, and channel teams. You will operate at two altitudes: building the strategic narrative for security executives while earning the trust of the practitioners who evaluate and use the product. Portfolio Strategy, Positioning & GTM Ownership Own the end-to-end product marketing strategy, positioning, messaging, and launch plans for NodeZero Internal and Cloud Pentesting. Define the portfolio narrative across internal networks, Active Directory and identity, AWS and Azure environments, Kubernetes, hybrid-cloud attack paths, and related exposure-validation use cases. Translate the “hack, fix, verify, repeat” operating model into clear value propositions for CISOs, security leaders, SecOps, ITOps, cloud-security, identity, vulnerability-management, and offensive-security teams. Build persona-specific messaging and conversion paths for Enterprise, Mid-Market, and Commercial segments, including both technical champions and executive buyers. Develop annual and quarterly GTM plans that connect product priorities to pipeline creation, win-rate improvement, customer adoption, expansion, and measurable risk-reduction outcomes. Lead product launches and major capability releases from market insight and narrative development through enablement, campaign activation, and post-launch performance review. Technical Product Marketing & Proof-First Content Turn complex offensive-security capabilities into technically credible, differentiated, and commercially useful stories. Explain how NodeZero safely discovers exploitable weaknesses, chains attack paths, validates impact, and verifies remediation across internal, cloud, identity, and hybrid environments. Develop proof-first content including solution briefs, technical blogs, buyer’s guides, product pages, demo narratives, webinars, customer stories, analyst materials, and executive-facing POVs. Build a repeatable library of evidence around production safety, agentless deployment, recurring testing, attack-path visibility, prioritized remediation, and one-click verification. Collaborate
