Senior Product Marketing Manager, WebApp

Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to enabling organizations to proactively find, fix, and verify exploitable attack vectors. They are seeking a Senior Product Marketing Manager to lead the go-to-market strategy for their NodeZero WebApp Pentesting product line, collaborating with product and engineering teams to drive market dominance.

Responsibilities:

• 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
• 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
• 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
• 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

Requirements:

• 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
