Senior Product Marketing Manager, WebApp

Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix, and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, 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.

About the Role

We are seeking a Senior Product Marketing Manager to lead the go-to-market engine for our newest, most explosive line of business: NodeZero WebApp Pentesting. You will be the entrepreneurial marketing lead for a massive expansion into the application security (AppSec) and Application Security Posture Management (ASPM) space. The market is currently being reshaped by AI hype, creating a distinct window of opportunity for a fierce competitor to seize total market ownership. You will report directly to the VP of Corporate & Product Marketing, partnering tightly with a world-class Product and Engineering team to turn deep technical capabilities into market dominance.

Go-To-Market Strategy & Launch Ownership

• Own the end-to-end GTM strategy, messaging, and positioning for the NodeZero WebApp Pentesting product line from its launch to market dominance.

• Architect an aggressive, pipeline-driven product launch framework that moves product marketing to a core revenue driver, not a corporate support function.

• Define target personas across Enterprise, Mid-Market, and Commercial segments, building a product narrative that maps directly to clear conversion paths.

Competitive Positioning & Content Weaponization

• Drive the competitive narrative, explicitly dismantling legacy DAST incumbents and exposing fragile, unscalable "agentic AI" wrappers.

• Educate the market on why generic AI solutions suffer from exploding token costs, erratic inconsistency, and severe production risks, while positioning NodeZero’s combination of a deterministic foundation and surgical AI as the only enterprise-grade choice.

• Develop proof-first product content, technical teardowns, and competitive battlecards that arm the sales force to win contested deals.

Product & Engineering Collaboration

• Partner tightly with Product Leadership and Engineering teams, embedding yourself with the builders to transform highly complex offensive security capabilities into high-impact, market-facing narratives.

• Translate deep technical breakthroughs, e.g. the autonomous, production-safe exploitation of complex business-logic flaws like BOLA and IDOR, into clear, hype-free value propositions.

• Serve as the vital feedback loop between market realities, buyer pushback, and the product roadmap.

Sales Enablement & Foundation Building

• Own the technical enablement motion for the direct sales force, SDRs, and channel partners including major VARs, resellers, and distribution partners.

• Win the hearts and minds of cynical, hype-hating developers, AppSec leads, and red teamers who demand zero false positives, while effortlessly elevating the message to the CISO/VP level to tell a broader platform and cyber-resilience story.
  Build the foundational processes, sales tools, and customer story pipelines required to scale this product line.
  

• 5+ years (PMM) or 8+ years (Senior PMM) of B2B product marketing experience, with meaningful time spent launching and scaling complex technical products in a high-growth SaaS or cybersecurity company.

• Non-Negotiable Drive: High-agency, self-starting execution. You thrive in greenfield environments where processes don't exist yet, and you love the challenge of defining what "great" looks like from scratch.

• Deep Technical Chops: A background as a former security practitioner, pen tester, technical marketer, or technical PMM who has shipped AppSec, ASPM, or AI-driven security products. You must understand application architecture and the adversarial mindset far deeper than just cybersecurity acronyms.

• Dual-Altitude Communication: The rare ability to build deep trust with highly skeptical technical practitioners who demand absolute production safety, while seamlessly translating those technical truths into business resilience metrics for CISOs.

• Demonstrated capability to manage high-stakes product launches, cross-functional lifecycles, and performance frameworks with a clear ROI lens.

• Proficiency with Salesforce and product analytics tools for tracking launch metrics and pipeline attribution.

• Hands-on experience with web application security testing tools (DAST, SAST, IAST) or ASPM platforms.

• Deep understanding of the current LLM/Agentic AI security landscape and its practical architectural limitations.

• Experience working in an account-based marketing (ABM) motion with highly targeted enterprise buyer personas.

• We are a fully remote company. This role requires up to 20% travel for key product launches, major industry events, customer interviews, and internal offsites.

• Job-related travel expenses are reviewed and must be approved by your manager.
