Horizon3.ai is a fast-growing, remote-first cybersecurity company building NodeZero®, an autonomous platform that executes real attack techniques in production environments to help organizations identify exploitable weaknesses, verify remediation, and continuously prove resilience. The company was founded by former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners focused on solving critical industry problems: ineffective tools, false positives, alert fatigue, blind spots, and cybersecurity skills shortages.
As Director of Product Marketing, you will lead the product marketing function at a critical growth inflection point. You'll report to the VP of Corporate & Product Marketing and manage a team of three product marketers, working cross-functionally with Product, Engineering, Attack Research, Sales, Solutions Engineering, Customer Success, Demand Generation, Corporate Communications, Alliances, and Revenue Operations.
Key responsibilities include:
**Product Marketing Strategy & Category Leadership**: Define and execute product marketing strategy across the NodeZero platform, aligning portfolio priorities with corporate narrative and growth objectives. Establish a clear architecture showing how Horizon3's capabilities—internal, external, cloud, identity, Kubernetes, web application, precision defense, threat detection and response, and compliance solutions—fit together as one proactive security platform. Lead the evolution of market positioning from autonomous pentesting toward a broader, evidence-based proactive security and CTEM operating model. Translate product and market strategy into clear buyer narratives for CISOs, security leaders, SecOps, ITOps, cloud-security, identity, application-security, infrastructure, compliance, and offensive-security teams. Identify highest-value market opportunities, buying centers, use cases, and customer segments. Serve as a senior product marketing voice in executive planning, board preparation, analyst engagements, and strategic customer conversations.
**Product Launch & Go-To-Market Operating System**: Create and scale a repeatable launch methodology aligning Product, Sales, Solutions Engineering, Customer Success, Demand Generation, Communications, and channel teams. Establish launch principles, stage gates, briefs, roles, timelines, readiness requirements, and measurement standards. Ensure every launch begins with validated customer problems, differentiated market positioning, clear audiences, proof points, field activation plans, and defined business outcomes. Oversee development of messaging, positioning, pricing and packaging inputs, buyer journeys, launch content, campaign requirements, enablement, analyst materials, and customer communications. Create consistent processes for moving product feedback, field intelligence, customer evidence, and competitive insights back into Product and executive decision-making. Measure launch performance and use results to improve future launches and go-to-market efficiency.
**Team Leadership & Talent Development**: Lead, coach, and develop a high-performing product marketing team with clear charters, ownership boundaries, priorities, and success measures. Set high bars for strategic thinking, technical fluency, customer empathy, writing quality, operating discipline, and commercial impact. Build an effective portfolio model allowing individual PMMs to own their areas while maintaining consistent company-wide messaging, process, and standards. Recruit, onboard, mentor, and retain exceptional product marketing talent. Establish regular team operating rhythms including planning, work-in-progress reviews, launch reviews, skill development, and performance conversations. Create opportunities for the team to build reusable assets, deepen customer and market expertise, and increase leverage through repeatable systems and AI-assisted workflows.
**Revenue Alignment, Enablement & Customer Adoption**: Partner with Sales and Revenue Operations to define how product marketing contributes to pipeline, conversion, deal velocity, win rates, expansion, retention, and customer value. Develop a consistent enablement system spanning messaging, discovery, qualification, solution narratives, demo guidance, objection handling, competitive responses, sales plays, and training.
